any help with this one? i know heat can cause cupping but ive been growing in a greenhouse with the same temps for 5 years. the Ph was 7.5 of the soil but i corrected it more then a week ago. (new water source and forgot to test the ph. oops). and i have started a nutrient buffet to try to help out to.
Tiger bloom
grow big
cal 20
micro nute spray by foxfarms
microbe brew fox farms
microhoriza
compost tea
flora nectar
humic acid
super thrive.
Oh yeah. this is only happening for the most part on the bottom half of the plants.
am i just being impatient or is there something else i should be doing??? thanks!DSCF2378.jpg

I just used some fox farm boomerang on some less that healthy girls in veg, and it worked real well, snapped them out of their funk in a week. I'm afraid at this point in flowering your crop is going to suffer some damage. I think the combo of heat stress and ph may be causing some nutrient lock out. Hope you get it corrected fast so you can still have a bountiful harvest day.

Yeah i am afraid i wont get a bumper this year... luckily my girls are only roughly a week or two into flowering depending on the strain and only the bottom half of my girls are showing symptoms. thanks for the advice. i saw that stuff on the shelf when i bought my buffet... dont know why i didnt buy it but ill give it a try. thanks!

Norstar pretty much got it on the dot imo, however im interested to see these dying pistils your talking about that sounds very strange. I would personally recommend revive from what I think is advanced nutrients.

cali thc. You cant see the hairs that have already turned on me? i can take more pics. one of my assumptions with that is my foliar feeding. it might have burned them up. my last spray i thought the clouds were going to be out the rest of the afternoon... were i live i really made a bad choice making that assumption.

What are you foliar feeding with? I remember last crop i got mites and I made my own mite solution. Sprayed the plants,with the lights on(because I am dumb) and the next morning It looked like I doused them in acid, however I believe it was the shit I put in the mix because I have foliar feed with lights on before.

Cal 20, super thrive, and the micro nute spray from fox farms( cant recall the name now.) . i nixed the superthrive now and am just using it in my drip line with the rest of my nutirents listed above.
Since yall gave some helpful tips... dr bronners peppermint castile soap works great for mites! dilute 3 tbs per gallon but start at 1 or two tbs per gallon to make sure your girls dont burn. Its cheep as hell compared to what you can find at the grow store (i get it at a health food store) and it works a year ago i had enough damage that in a week or two i woulda been seeing webs and used that stuff every other day for a week then once a week after. they were gone!

I just hang up a hotshot no pest strip and leave it in the tent, no flying or crawling insects, ever. I only foliar feed with bmo foliar harmony now and that sounds like alot of shit to be foliar feeding with but I wouldn't know. Ive had dodgy experiences with ST as well.

I heard there is a big infestation of russett mites going around Norcal. The symptoms are curling starting from the bottom of the plant. You guys might want to check into that.

I read they can even lay eggs and survive winters on seeds. Sounds like some devastating shit.

You will need a microscope or jewelers loupe to identify them if that is the issue.
