Revised: The Complete Guide To Sick Plants,pH and Pest Troubles - PlanetGanja.com
I'd start very first by checking your soil ph....
when you are watering, do you just add water to the plant or do you flush the plant? It looks like a pH thing to me, if it was nute's you would see the tips of the fan leaf curl'd down and brown/dried..... there are couple of testers out there that will let you test the pH of your soil and see what nute's you have there as well. If you havent flushed your plants, i would do that right away...
you have a calcium & nitrogen def
complete a soil runoff PH test.......
with PH corrected water (6.5-6.8PH ) pour enough water in the pots so the water runs out the bottom of the pot ...collect & test the PH of this runoff water....
If the PH reading is out of optimum range 6.5-6.8 PH, you need to flush your plant.
Flush with PH corrected water, till in optimum PH range, 3 times the volume of the pots is the rule of thumb but may require much more flushing if the rootball is thick & sour
EG: 1 gal pot = 3 gal. flush
add 1/2 strength nutes to the last gallon of the flush.
^^^^ Right on.
N= you can see the paleness of the leaves.
Ca= you can see the wide band of necrosis along the leaf margins.
Flushing will help you. Be certain that your nutes contain secondary compounds, not just NPK.
i flush them, but i dont want to flush that much because im afraid to overwater. the pots stay very heavy. i use ferts with all compounds and NPK 6-5-6.
someone can correct me if i am wrong, but flushing every couple weeks is a good thing and you should do it right away, you will see a difference (personal experience on that one) and then add a nute solution (just like stinky mentioned) that has secondary nutes, you can see the secondary nutes on the box of fert that you use.
At this point, it's a little more important what the plants want than it is what you want!Quote:

my soil have little drainage and holds more water and my fear is because of that. right now i use tap water with ph 6.8, and soil ph is 7.0, i think this is fine. i put them in 12 hour dark period with one fan blowing on them.
cannabis likes/needs airy medium, if your having drainage issues you could be in the risk of root rot as well, keep that in mind, you might have to either drill some holes in the medium or if you have a cap on the bottom of the pot that holds water to take it off and let the water drain, even if it is a very very slow drain.
thank´s for you´re tip whatsthatsmell. i have 4 to 6 holes at bottom of the pots and i take the cap at the bottom of the pots. when you say drill some holes in the medium, you mean the medium of the pot or in the bottom medium?
you can drill some holes in the pots towards the bottom, but depending on how slow your drainage is, you might want to drill some more higher up as well, dont go to deep to hit the roots, you just want to drill holes in the plastic. Then go get some chinese take-out, grab some chop sticks. use one chop stick to poke some holes into your medium, being careful not to kill your roots, this will help get some air into the root system and also help with the drainage. You dont want your medium to hard like the ground around your house, when you do the flush, seeing some air bubbles coming up is a good sign.....
Hope that helps
ok now i understand, i have to drill some holes in the medium(soil). my medium is not hard is soft but hold the water very well and have normal drainage. but seems to me that holds more than drain out. tomorow i see how the babies are, and i wait till the soil dry to make another flush with more holes at bottom and make some holes in the medium. later i tell if work. thankz whatsthatsmell.
i flush them 2 days ago and they get worse, what i have too do more, flush again? or not water at all? please help.
Did you give a dilute solution of nutrients with the last flush?
You can foliar feed in the meantime.
no i just flush them with tap water, here some pictures.
i can foliar feed with nuts half strenght? or less?
today i discover some larvae from withefly and spray them with insecticide. could this be the problem?
p.s. the pots are very heavy with the flush thing. some of the bud leaves start to have the same problem curl down and burn tips yellow leaves and some dark brown. only the top leaves point upwards the rest of the fan leaves curled down
can anybody help me here?
Drill some more holes in your pots right now, they aren't draining. To start with go about 1cm up from the bottom of the pot and drill a 1cm hole. Do this 6-8 times around the bottom of the pot. (Next time you grow, mix about 30% vermiculite in with your soil.)
Are you adjusting the pH of your water before you put it into the pot?
PC :smokin:
i dont need to adjust the ph of the water, the ph of my tap water is 6.8, i read in some book the correct ph of water should be 6.5 to 7.0, is this right?
im go to make some more holes in pots, is just this ones that give me problems the others plants are just fine. i think that maybe they have some kind of lock up nuts, what did you think? they not lost any smell, and if was overwater they smell kinda rot, so this is out. this is because my friend told me that i overwater this ones, but i think that is not the problem.
P.S. any tips welcome.
here today photos from them. the last one is the less damaged but the other two got me more problems and disease plants atract more insects. what should i do? they smell good but the leaf problem make me fear. i dont want to lost them at this point of flowering. i have this problem once with two plants, and one live and give me great compact buds(she recovery very well) but the other die in front of my eyes(in the 4 week flowering).
please HELP!
what is the pH of your run-off water? It looks like there is some pH issues and also some micro nute issues as well. Your leaf turns up is an indication of Mg def, and your older leaf being burn is an indication of N, and Zn, so when you test your run-off water for pH, make sure your last one placed in the medium has the mircro nutes as well...
if your in week 4 of flower are you adding any bloom boosters or anything??
no i dont give any bloom boosters in week 4 of flower, but this ones dont have 4 week of flower, maybe almost 3 week. right now i give water with nuts NPK 6.5.6. and micro nutes as well. right now i stop with ferts to see how they react.
p.s. i fert them only once per week with nutes half strenght.
the runn-off water have the pH 7.0. is this high?
my fert have macros NPK 6.5.6., micros is Boron(B), Copper (Cu), Iron (Fe), Manganese (Mn), Molybdenum(mo), Zinc(Zn), Magnesium(Mg) and Guano. i use this nutes in the past 2 years and get wonderfull results. i just dont know what happen with these 3 plants the rest of my plants are very good healthy.
your not in the ideal range of pH for your soil, try and get that down to 6.5 - 6.8. your also in the 3rd week of flower so your plants NEED nutes, i think your nutes are not enough, but you can test for that, there are some test kits out there to find out what your nutes are in your medium. One other thing, i was looking at your pics, do you have more than one plant in per pot or are they "topped". I'm wondering if you are short on the pot and you might also be root bound. This will result in your plants not getting the water and nutes they need.
yes i have one pot with two plants, but the pot is large enough to support them roots. i think i discover whats going on, they dont get enough air in soil, so i take some soil in top pot and i make some holes in medium pot with chop stick, and today i foliar feed them with nutes half strenght and tomorow i water them with more nutes. maybe almost full strenght, is that OK?
i already flush them but they dont change much, instead they get worse. so maybe the problem is lack of nutes, like you say so. i update this thread.
if you have been watering with half nutes while in flower, then yes, you need to get them some nutes, get some room for those roots to grow. The biggest problem your gonna have with 2 plants per pot is that they will not get the amount of water/nutes they need, and i think your bud will not be as good as it could if they were in pots by themselves. always keep in mind that you want 1:1 ratio for your plants when you put them in pots. so if your plant will end of being 5 foot tall, you need a 5 gallon pot, now if you have two plants per pot (not recommended) that will be 5 foot tall you will need at least a 10 gallon pot but again if your doing that your plants will not get the nutes they need as they get older.
i have all my babies one per pot, except for that one i put two. now i realize i make a mistake but i dont want to transplant them, because they are in week 3 of flower and i dont want to stress them right now, but i check the soil and they have plenty of space to grow roots. i dont make this mistake again for sure. rule of thumb 1 plant per pot, i know. thank for all your help whatsthatsmell.
no problems, good luck on your grow :jointsmile:
here udate. two of them are recovery but the other one is get worst every day, i dont no what i have to do more. i think with the flush i made a big mistake or not. i been do foliar feeding and dont water them 4 days now but the soil is still humid. what should i do more? in the first pic, the one from right is get worse every day, the one from left is recover, they are in the same pot. the second pic she get better, and the last pic she have the same problem as you can see. i need HELP.
Whats your medium? It looks as if you're using straight compost w no pearlite or vermiculite? I would say thats your problem! Even with those holes in the bottom of your pots, it doesnt mean it's gettin proper drainage. I'd bet the bottom of your pots are clogged w mud and old rootmass.
I'd agree, if soil is still moist after 4 days, you're not draining well ... think you're on to something there ... the damp soil would also account for the yellowing of the leaves ... :jointsmile:Quote:

so who can explain this? they are in same pot, but one is recover the other is like you see getting worse. the soil is almost totally dry, i dont water them for the last 6 days. as you can see in my first post they are a lot better before the flush, than after the flush. big mistake. i stop with foliar fedding and water, and one is get better but the other is get worst, what can i do? here the last photo take today. almost all the fan leaves drop and i cut dead material from the one in right. i need advice.
You need to check the ph of your soil runoff.
Okay, this is advice, ...noob to noob!:D
1.)What I would is tip those pots on their sides and VERY GENTLY slide the soil/rootball out of the pot.
2.)VERY CAREFULLY as not to disturb roots too much,remove as much "loose" soil as possible. (Paying a GREAT deal of attention to safety of roots, also in fairly dark area)
3.)Mix a 50/50 pearlite new compost.
4.)Refill pot with about 6'' (or more if neccesary) of new mix.
5.)CAREFULLY reset plant back into pot in new soil, making sure roots are optimally arranged.
6.)Fill sides of bare rootball, bringing the base of your plant up to the rim of pot.
7.)Add 1-2 drops of superthrive to straight water and run full gallon through.
8.)Following day, take a pH runoff test, should be between 6.1-6.9 if I recall correctly.
9.)Start back on reletive nutes. (Obviously small dose)
10.)Hope to hell I wasnt too high when I wrote this advice!
SHOULD get you headed in the right direction:thumbsup:
I am also kinda hopin' to get some feedback myself on this advice from some of our more experienced cultivators!
With a flowering plant, or one that you are about to put into flower, I wouldn't try to remove any of the soil on the root ball.
pH should be 6.5-6.8
Small dose nutes for the first watering, then back up to normal.
Other than that, you're all set.
Chat?
how can i do to chat with you stinky?
so i doing the things that have to be done, stinky? the pots today loose much weight and they are almost complete dry, i think water them tomorrow with plain water or add 1/4 or 1/2strenght nutes? what you think stinky? is this problem affect my weed potency? the babies kinda slow growth in last week because of this.
i am a newbie but i know a few things.Quote:

3-so in this case is a little more important try everything else and for last resort a soil flush.
4-a soil flush causes the plant a great deal of shock and should only be attempted as a last resort if your plant is dying and can not be cured by any other means.
now you understand why i dont want to flush it before try other things.
Actually a soil flush is not just for a dying plant.
I flush my mothers every time I take cuttings from them. They live in small pots and I fertilize them aggressively, so a flush is necessary every once in a while, and doing it at regular intervals prevents problems with salt buildup. It's good for them!
I promise it is safer to flush your plants than to let them sit in poor soil.
The problem I see is that your soil does not drain well. That makes flushing harder, but you still need to do it, test the runoff pH, adjust your flush water to bring it within 6.5-6.8 if it is out, and then do a final flush with some fertilizer solution.
i already make a flush 1 week ago, and i dont see any improvement in my plants, only see they get worse. but if they survive to that flush(it is sad to say but very few plants do survive such an emergency soil flush.the soil flush is, in its essence over-watering your plants to the point of removing most of the minerals and ingredients in the soil.) they now start to recover from the damage of soil flush?
other thing tomorow when i water this plants, should i add nuts to the water at 1/2 strenght or less? or give just plain water?
