There is a thread on hear somewere and the dude had grw blueberry numerous times and he put down ppm for nutes soil and hydro and im sure he never went over 400 ppm in soil grows thats how sensative blueberry can be but its well worth the effort and is meant to be up there with the best. be safe the postman
ar! just had a thought! its.. That there over N fed because the strain is so sensitive but also over P like stinky said, would that cause those effects?
Guys I cannot answer anything about PK ratios etc....especially in soil. I'm still set on a humidity issue. my opinion only. :)
yea i was feeding them 600 ppm and they were still over fed! mad.Quote:

tom, koolbloom is 2-45-28..their first dose of k/b was given monday night I believe it was, I want to stray away from the schultz a bit if the plants are happy with the koolbloom just because it makes me weary of over feeding them...
Stinky, ratio may be high, but I've done 2 previous grows with schultz and although the grows never fully completed, my flowers were nice and healthy..
I agree that leaves have a slight ph/problem look to them and may could be attributed to homemade fungicide with baking soda/water..? high ph level of the spray is supposed to be effective at making it unsuitable for mold to survive..maybe it did that to the leaves? there are spots on the leaves that very truly looks like mold to me...and I've read that sometimes mold infestation looks like nute burn because of the way it affects the tips of the leaves...the way some of the leaves are yellowing and falling off almost makes me wonder about lack of nitrogen..
dave, today makes 4 weeks into flower.Quote:

but you have so many things going on I am hesistant to point at any single factor and say, that's your problem.
Guys since the discussion has gone to soil I'm going to back out of the equation.....there are far more experienced minds here for soil than mine. I will follow this Mark and wait to see what the actual issue seems to be. Whenever I think of soil I cringe so better I observe. :D ;)
with calcium problem, I've looked at pics in problem threads for calcium, have spots yes, but I don't see much as far as yellowing and falling off...that's probably moreso than the spots...the stems get really weak where they connect to the main branch and once are completely yellow you can merely touch them and they fall off..Quote:

When in doubt,
-Flush your soil like a mofo
-pH your soil to 6.8
-use a complete fert, perferably cannabis-specific
-if your plant is more than 12" tall for every gallon of soil, or shorter if it aggressively trained, put it in a bigger pot with a quality compost and lots and lots of perlite.
This procedure will solve most problems that are not related to temps or humidity or overwatering or bugs.
Mark I got my dehumidifier and had no idea how tiny they were.....I was thinking maybe 18 inches but it's alot smaller than that. I've already ordered a second.....
Actually I'm pretty happy w/my diagnosis. I think you are seeing normal yellowing of fan leaves during flower and because they are dying they are the ones most likely to get leaf spot.......which is what I think that is. Mark may have a point about the baking soda but I don't think that is something that will harm the healthy leaves....witness those nice buds. The weakest leaves are taking the brunt. I thought that was normal for a plant. ;)
Mark did you say that puppy brought your humidity down 10%?
yeah, I can say about 10%...I hope you're right, weedhound..it'd pop my top if my buds started getting affected..still working on getting a big dehumdifierQuote:

Am I wrong in thinking that you will not make the same mistake twice? That is what I am betting on. But ultimely of course, you have to make the decision what is best and I will certainly support you no matter how you go about dealing with it. These people have much more experience than I do in growing in soil.....no question there. I do think, though that you will have issues until you can solve your humidity problem. My feeling is that you are trying to cure an infection without penicillin or something......you can only do so much. That's why I think you need to get drastic with things. Cut those damaged leaves. Put fungal spray on a rag and wipe down your walls with it. The more proactive you get the more you will hedge your bets. ;) (Disclaimer: again....you must follow your own instincts...)
My camera totally sucks w/close-ups so unless you want a shot of a big fuzzy blur I'll have to wait until I get my cool new one. :D
I must say though.....I've been an uproar myself since discovering my own humidity probs. It's funny how fixing one problem opens up the door to another. :wtf:
i still agree with stinky! :)Quote:

Yeh man ! know what you're on about there.Mark have you checked the buds for any sign of mold as if its in your room it will be around the buds ?the bottom of the stem of the buds usualy will show signs of mould as it spreads really really fast .Its a bad problem to have in flower especially at the half way stage.So as weedhound says take drastic actoin and get those affected leaves off and wash down the walls.can you get a hold of a sulpher burner and some sulpher tabs or someother method to rid you of it.
You gotta act now if you beleave its mold cause beleave me it spreads real quick and will affect the buds quickley also it yellows the leaves around the buds just like what happens natuarly in late flower. best of luck and hope you get to the bottom of it.hears a pick of a buds that had mold in the last half of 12/12 i never noticed till harvest time be safe the postman.
mark, i may be way off here, but, did you treat for mold when the lights were on? it looks to me like there was water on the leaves while the hps was burning, creating hot spots that burnt where ever there was water; i could be way wrong, but it looks identical to the problem that i had with my first shot with neem.
it looks like a deff or lockout, but then again, it doesn't.....
Hey Scarlet....I thought your gecko was a male. ;)
Postman.....what a cool pic. :thumbsup: You sound like you've been there and done that with mold.
Tom I like a man (or woman) who stands by their belief. I will do the same. ;) I get afraid of too many cooks spoiling the soup but realize these minds are excellent soil growers so will step out if Mark takes another route cause I sure don't know anything about soil ph etc and I don't want to screw things up for Mark which may happen if I throw something into a recipe that I am clueless at.
btw....love your shed. :thumbsup: That thing totally rocks.!!!!!!
Postman I can't enlarge that photo. Is that just me? :(
one male, four females; one happy orgy; i mean family :DQuote:

Thanks for the pics but I notice you did not mention mold issues in your thread. (or not on the page i looked at anyway.) How did you find out what the issue was?
ps nice-assed buds btw
m missed this earlier. you asked what is flushing. Well Loc Nar, had the end/finish flushing covered, but if you have an environment or toxidity problem...with a waterfarm you just need to empty your rez, and add ph5.8 water. (((soil 6.5.)))
anyway, turn pumps on for an hour or 2. then add fresh batch of nutrients.
However, you are done...so just remember this info for next time. Peace
You know going through that thread and looking at the pics weedhound i can now spot the signs of the mold probs but at the time i didnt think there was a problem i thought it was just a bit of heat stress and later the natural yellowing of leaves in flower but when it came to harvest i had mold inside some of the buds not bad but it was there all the same:mad: and looking now at the prob i put down to heat stress it may well have been signs of mold.Im taking the same stance of you on this one and stepping out as you said i dont want to be responsible for wrong diagnosislol.as you said to many cooks can spoil the broth but i will be following this with great intrest as plant problems is one of the areas of intrest for me. so mark follow your head mate you will feal as to what the real problem is hear.best of luck and be safe ,. the postman.
I like it postman!!! You go!!!:)
:D lol! maybe is a bit of both? :)
Could be could be Tom.....my reason for running is because the moment the issue steps away from mold into something else I'm useless. And being useless always reminds me how old I am... :D ;)
Never underestimate the value of a healthy immune system in a plant.
A stressed plant is more prone to disease.
Potassium is important for a healthy immune system.
If it is locked out, you are going to have problems.
Also, Silica is beneficial to strengthen your plant's defenses.
Very true Stinky. I also found what postman said about the mold attacking only one strain interesting so differences......even in the same growroom.
Yeah, even with bugs, sometimes I see one plant get chowed and others untouched.
Lately the thrips have been after my White Rhino crosses. Yet the SourBubbles right beside them are healthy!
Chowed, lol. Haven't heard that botanical term before. Learn something new every day. :)
:wtf: Funny you say that about potassium lockout stinky cause this pic of marks below .I have had this before with a potassium deficiency could this be a nutrient deficiency rather than over fert ?pic 2 also looks like a deficiency prob rather than a overfert the leave seems drained rather than burned. lol sorry i can leave it alone:D
Well I AM positive about one diagnosis....Mark would be thrilled if the problem could be fixed....;)
yeh i totaly agree.
here's another of a fan leaf I pulled off a bit ago..koolbloom is really starting to make these things get with it...only my topped plant is having yellowing issues really..it's the second thumb you posted dave is leaf from it...first pic is of the one
Pic 2 of Postman and pic 1 in last set of MArk's both show what I believe to be Calcium def, where the leaf gets necrotic near the origin of the fans, rather than at their tips.
Lockout or deficiency; either way, the plant is not getting what it needs.
But there are also signs of tox, so I'm going with lockout.
This thread is going to be going long after the plants are just a puffffff of smoke...
So have you flushed yet?
Flush man flush! :D
another things for sure you got some nice bud coming there mark:jointsmile: :D
thanks dave, as for flushing, no big serious amount, they each get 64 ounces of water, about 4-6 ounces runs off...not as much as I'd like to run through there, but it'll have to do. I cannot move them out of the room and I cannot run much excessive water through due to humidity problems. Next couple times they'll get fresh clean water.
