If some one can help please !!! So i have them under flourescent tubes about 2-3 inches away, water when they get dried out(every couple days) and just yesterday gave them some 20-20-20 plant food with their water, they looked like this before i gave them food though,bottom leaves are dying off and it appears to be spreading up the plants.Any suggestions would be much appreciated, thanx !!
When did they start looking like this? Did you give them fert to try and fix the problem? Cause that looks more like some type of burning from within rather than a nute defficiency. That was your first time feeding it? Even if it was that's still too young for food, I'm not an expert though.
20-20-20 is very strong for such young plants.
Water them to the point where the water runs out the bottom with plain tap water.
Test the pH of the runoff.
Check that it is between 6.5 and 6.9.
They are a LITTLE small to be feeding yet, and the first feeding should be with a much weaker fertilizer that is a real grow fert, such as a 6-2-2 mixed to half the recommended strength.
They started looking like this about 5 days ago, no i didn't start giving them food to fix the problem, i just thought they were ready for feeding.And yes that was the first feeding.I don't beleive that they are close enough to the light to get burned but maybe,well no i guess not because one of the babies that is doing this,wasn't as close to the light.
Well that explains why they looks so crispy, it's been deterriorating for a while now. It's not the light I can tell you that. If it were, those leaves would problably be brown by now. Plus you would have more damage on the top of the plant assuming you have most of the light overhead. I suggest you take stinkyattic's advice.
Don't know what your soil is but I imagine it has ferts already in it? Those things are nuteburned for sure.....which may be due to abnormal ph in the soil or....ferts already IN the soil.....plus you just added MORE ferts.
Are the plants still with you? If so....as the Stinky says....flush like hell.
They are in miracle grow potting soil,so yes i will flush them out, any idea on how much water to run through them ?? And i think i have another problem......i just tested the ph level of the tap water i was giving them from the start and the ph is about 7.4 and that is bad right ?? i am thinking of going and getting bought water from the store for them and check that ph level. Or is there a way to lower or raise the ph level in the tap water prior to giving it to the plants ? And when can i tell if they are males or females ?? Thank alot guys !!
Mg prefertilized soil is a big NO NO in growing. It is a proven fact that that soil kills small cannabis plants. Just to mch nutes in it for small plants like that you want to get organic, transplant, and give it plain water for a week. Then feed regularly.
I like bud expresses idea...a transplant would sove all your problems if you use quality soil (fox farms oceans forest I has been recommended to me) but if you can't transplant then I would flush those plants heavily with ph correct water (6.2-6.8) 3 -5 x the size of the pot (1 gallon pot....3-5 gallons of water) By the end of your flushing the ph should be the same going in as going out.
Id like to recommend 1/4 strength nute mix at the end but not that 20-20-20 stuff at all so don't unless you have something along the line Stinky recommended.
Is your lighting on 12/12? If not no...you can't tell at this stage if they are male or female. Without that info or how old they are etc.....plus photos of the nodes who knows he or she.
You can use baking soda to raise ph in a pinch and distilled white vinegar to lower it.
DONT use ph adjusters for aquariums....fyi.
Good Luck.
What is "disstilled vinegar" ??? When i went to go buy it i couldn't find one that said that, they said " Pure white vinegar" Any help? And my lights are on 24/7,don't know if the light is sufficient???i will post pics.They are 2 daylight bulbs and 2 full spectrum sunshine bulbs, both 4 feet long.I bought 18L of water from the store and tested the ph and it was about 6.8 so i gave the ones that are already transplanted lots of water, and i need to get some good soil to transplant the others.
Ok....we'll worry about sexing them later then. Pure white vinegar or lemon juice will work ok for you in an emergency but buy some good ph up/down from the hydro store when you can.
Flush them out really well, check the ph of your soil runoff and let them dry. Your lights are fine for now.
Good luck.
20-20-20 is the same as 10-10-10, isnt it? so hows it stronger?
but def. a ph problem. try flushing it a few times
No it isn't the same as 10 10 10.....its DOUBLE the strength of 10 10 10. Basic math.
Pokherking, that's a good PH for unbalanced water, what brand of water was it?
Bottled water is not good for plants.
Use tap water or RO water with calmag added to it.
You need the Ca/Mg. And bottled water (mineral water) has too much Na.
It was one of those water jug filling stations at the grocery store, it was at pricemart and the water brand was "western family" purified water.
calmag ? ro water ? please define, new at this my friend.my tap water has ph level of 7.4 and that is too high and i can't find anywhere or anything to get my ph lower, weedhound suggested vinegar but only in an emergency situation and not permanantly.There isn't a hydro store near by.
Poker,
Your friend had better start reading and researching quick if he wants his plants to make it. Good intentions are NOT going to make those plants grow and be healthy....only time, knowledge and energy. :cool:
Tap water....the stuff coming out of your faucet. Use the lemon juice to drop the ph....and check ph carefully. Order some ph up/down off the internet if you have to but you need to do some serious research and get your basics down.
No matter WHERE you get your water you need to check AND adjust ph if necessary...I don't care WHAT kind it is....your faucet, the store, the OCEAN. .ALWAYS check ph of your water and solutions before adding ANYTHING to your plants. ;)
Good luck. I'll be right back with a good link for sick plants for you to look at too.
this is a very good link.

Pharma Can is right.....I should have given you a starting off point. Sorry. :(
Hey, you were on a roll with the scolding, Dawg, and it needed to be said. :thumbsup:Quote:

u know what guys.......i spend hours upon hours researching this ,i didn't just come in here and try to get handouts, just some advice, i do have a job as well and can't spend 24 hours a day researching, and i thought my babies needed quick help, sorry for being a bother, thanx for the help and the link
Dude - Lighten up, no one is calling you a bother. :thumbsup:Quote:

Read the link in my siggy. That soil mix with the humus in it BUFFERS pH at 6.8-6.9 and you should be able to use even your crummy tap water! Without having to adjust, even! :D
That stuff at the grocery store is RO water. You must add CalMag Plus to it to replace valuable minerals found in tap water. Get it at the hydro shop.
So i couldn't transplant 2 of them cause they already were just about a weeks ago but the others i just transplanted into better soil, not the mix you have suggested cause this is all i could get unfortunately but it has no nutes in this soil and now they are still not doing good, worse even, i'm worried they are all gonna die ! The 2 that are in the miracle grow soil, i tried to flush out but it doesn't seem as if there is alot if any water coming out the bottom into my tray, there is holes in the bottom of the pot ??? i won't and haven't given them anymore store bought r/o water, but still have the trouble about having no hydro store nearby and my tap water's ph being to high. I do have some lemon juice to reduce the ph in my tap water but have been reluctant to use it. As well they seem soggy because of lack of drainage ??? First 2 pics are the babies that were transplanted into miracle grow with plant food.
