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

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

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

:peace:

well the superthrive is able to be given with every single watering and with your normal ferts. but again im no expert. the burning is affecting mostly new growth first. then moving on from there. I do have a fan also, a box fan, you just didnt see i guess. my temps in the room when i last checked was 81, so maybe it is heat stress since my air cooled light broke. but i do have Co2 which allows plants to take higher temps. i didnt check at the top of the canopy yet. I dont understand how its over ferting when im doing the EXACT same routine with my Ak-48 plant, that has no symptoms of burning, no nothing. straight green, tall healthy. beautiful. budding. but again each plant has different genetics, and all that crap. by the way im a chick :) thanks guys. oh i also inspected all my plants for spider mites, but i didnt see any.

Some strains get nute burned Waaaay easier than others.

Yup with the co2 81 is good

well its been quite a while now since the flush and the plants are still having the same problem... the tips turn brown and start twisting off.. Im getting so pissed b/c they look terrible .. i really dont understand it, all my other ones are looking great, nice and green and healthy. to me it looks like either nutrient burn or heat stress. but i dont know..

looks like over fert and too hot, to me. maybe put a fan near your lite and dont give as much food, and flush and see what happens from there, the plant looks ill, you must be doing somthing wrong without realizing. hope it get rite.the burnt tip thing means over fert. this happened to me when i fed soil plants hydro food for a few weeks, is they any build up on the back of the leafs.
