Some one, with experience please. diagnose this shit! what the hell. Usually I can figure it out. they keep on getting worse... Im not over fertilizing. the lights are not too close(foot away, i have other,bigger plants). they have co2 and the temps are in the low 80's... I fertilize every other watering, and give it superthrive when i dont fertilize.

first plant

2nd plant

Looks like light burn for some reason, hard to tell!

the only thing i can think of is over fertilization... Whats ur light setup??? ON THE FIRST PICTURE I SEE LITTLE SPECS ON THE FAN LEAF ON THE BOTTOM... LOOKS LIKE A POSSIBLE SPIDER MITE INVASION...

check the underside of the leafs for them...

i suggest laying off the superthrive tho...

it might just need some high quality H20

yeah thats what we did yesterday, straight water. I have a shitty 400 watt setup right now. my 600 setup broke a few weeks back.

i call nitrogen deficency. i see alot of the leaves are yellowing inside the veins, but the veins are still green correct?

"I fertilize every other watering, and give it superthrive when i dont fertilize."

Are you sure your not overferting, how often do you water them? The burnt tips look like overferting

definitely not underferting I rule that one out because of the burnt and curled ends of the leaves.

whats the temp in your grow room and also the temp at the top of your plants. The curling edges and everything else I see kind of looks like heat stress...temps in the mid to high 70's are ideal but you can grow fine if the temps are in the low 80's

Maybe its a mild combo of the two causing very noticable damage on your plants?

It does look as if you might have spider mites as well

it could be overferts. but my plants started to show the same symptoms of the yellowing in between the veins. i thought it was nuteburn/salt buildup, but it was nitrogen deficency. this just looks like a pretty severe case. but im no expert im just throwing out random ideas lol. he also stated his temps are in the low 80s w/ co2. so i dunno just my guess

Yeah but I think he is talking ambient room temps....the canopy could be alot hotter.

a severe nitrogen deficiency should show up on the lower leaves first then work its way up and the lower leaves would be alot more yellow with how sever his damage is....and his plants are just fried all over

I am no expert either but I have read dozens of articles on nute burn and deficencies and have some first hand experience

Also the leaves curling under like that are usually a huge sign of over ferting (too much N)

but seriously twisted thin burnt leave tips usually mean the light is too close.

12 inches miiight be too close especially if you dont have a f an blowing air on the canopy
