Ha, you're telling me! Look how fired up all of us got, and they aren't even our plants! It sounds like you're gonna be back on track soon. This is all a good thing really, because now you have experienced it, taken pictures, and whatever the remedy ends up being, you will know it when you see it again. It's like getting lost somewhere. Get lost in the same area twice, and the third time, you'll know your way around.
Hope it all works out!
Stay Safe!

thekingofNY said:So how bout everyone post what they think this ISNT, and a short reason why....heat stress; 80 degrees is perfect for cannabis sativa or indica, especially in veg. I have gone up too 90 the whole time the plant grew, although it was almost 100% sativa (i grew indoors)
I have also gone up to 90 degrees with very indica dominant plants with no problems, granted the humidity was non existent in both these places. (At lights off the temps would drop down to 78-80 for veg and about 5 degrees colder for flowering.
Sure this is fine if true, but a 600 watt hps in a closet at a foot or foot and a half is alot hotter (radiant heat) directly underneath than the thermometer at the side wall is showing. You are aware of the hot spot under a light? Radiant heat accumulates in the plant surfaces and stresses and burns. It's the light energy that is too much, not ambient heat of the space, although I do not trust that therm one bit to be giving an accurate picture.
Inverse, did you put the 400 watt in? Try it and see if it helps. If it doesn't, we can rule that out for sure.

yep i put the 400 in yesterday. its been in the mid 70's in my closet thus far. My plants all have perked up from the over watering except for the odyssey, which has been droopy this whole time haha =/. The plants look about the same as they were, except for my northern lights. The tips, as pictured in the last page, make like a 90 degree turn downwards. Now, brown looking spots are showing on some leaves, which remind me of the spots they showed a couple weeks ago which i believe you said was the beginning of a calcium def. if it gets worse ill take some pics, but would you recommend calmag if it is indeed a calcium def? lol anyways, i wont be able to tell if what im doing is working until the new leaves grow a bit more. do you still think those spots on the ak-47 is a virus?
edit::
heres a pic of what the brown spot looked like on it a few weeks ago. it looks alot like that now, except the leaf isnt yellowing

Looks like a mutation or something from a ph flucuation.

Hi,
Sounds like everyone gave this a good vetting.
One question I have is whether one's pH measurement device is calibrated and also accurate. Even though I believe mine is right as rain, I plan to take mine to the store and compare to the store's meters. It would be an unfortunate waste of time and money to unwittingly manage the pH environment with bad data from a meter that is not perfectly on target.
I think it is possible to have over-nuted an already rich soil-type medium creating a pH problem which leads to a lockout of trace elements, which manifests in the irregular growth and spots. Otherwise, plants seems to grow despite the problems. All those red discoloration in the stems and petioles, in the original pics on pg 1, are worth recalling, too. I might have experienced something similar. It's taken over a month to ease out of it, and still not cleared up.
Good luck and keep us posted.

I wonder what the effect (lock-out wise) of feeding with one part of a 3 part nute system in a 100% FFOF container. As a result of listening to hired help at the local hydro store, I was sold the G without the M & B.
So, I was feeding with 1 part of the 3-part AN GMB. This was the beginning of my problems. It happened before I started educating myself and attempting to learn the science. <grin>
What can an over abundance of nitrogen do in terms of locking out other elements?
Cheers!

ok guys. well my plants all have good new growth. ive started feeding them with grow big and will switch to big bloom soon. however, my nls which are 5 weeks old have been showing yellowing from bottom up. i fed them for the first time 2 days ago. im sure its nitrogen def, but what do u think these weird spots are? theyre completely dry, dead leaf tissue

Hello,
I wonder if the spots are from pH swings (?)
I'm interested in your diagnosis too.
Good luck...

Looks like possible phosphorus issue...... what nutrients you using now?
Purple stems and petioles ... bronzing spots with purple hues and in between the leaf veins..... looks just like a P issue, that is DEFIANTLY NOT a K issue.
WHat is your ph levels?
Ph gone out of wack recently? If your ph is fine and has been stable you need for P, switch to bloom. If it has been out of wack fix the ph first and then see if it goes away;... ph may be locking out Phosphorus depending on the ph.

I wish I could offer definitive advice.
It does appear, however, like a couple of those plants (not the light green one) are on their way to recovery. Seems like the older growth is area exhibiting the scars of things-that-went-awry in the past.
The light green one looks like it might, generally, be a heavier feeder.

I already said what his problem is; he is NOT feeding enough; his ph is fine.... talked to him last night and found out he was only feeding every other watering which he is only watering 4 times a month and feeding 2 times a month. His soil is depleted of nutrients from being in there more than 30 days. As I said previous post to this one...... nitrogen deficiency and phosphorous D.
