Yes sorry I forget you guys get Russet mite I’m in Australia I haven’t seen russet mite over here .. good call Dirtbag .OD .Could be heat, but that's also exactly how russet mite damage presents. I'd scope under the leaves with a magnifier or loupe looking for extremely small, 1/2mm long reddish brownish insects.
I had a plant in the living room window do this recently, looked exactly like that. I scoped it yesterday and sure enough it had russets. Into the burn pile it went.
Why not go 18/6? Save money on electricity, extend lamp life, further reduce heat...I checked that one whole plant from the leaf Dirtbag circled for russets and it’s clean, I’ll pull them all out one at time in the morning for watering and do a very inspection. Those dots on the leaf are particles from the ceiling, I was working on the light and mounting a fan in the room and the A/C blew dirt dust particles all over.
I raised my light a good bit and also plugged my timer back in and set it 20/4 cycle so maybe somesleepy time and less heat will turn them around... I’ll see how they are responding over the next few days.

Just curious, why do more than 18 hours of light in the first place?All good valid points for 18/6 cycle.
I ran a 20/4 cycle from seedling up until 5/28 with no signs of stress so that’s my reasoning for returning them back too the 20/4 cycle.
Looking back in my log I noted very slight leaf curl after the 24 light cycle switch but I contributed the curling too me over feeding. I slightly increased my feed ppm when I went from 20/4 too 24.
I noted my runoff PH was very low on the last feeding (4.9X~5.2XPH) and since that time the leaf curling has went from just new growth too some curling the top established leaves where before it was just the new growth only curling and after a short time straightening out as new growth happened and curled. My MG potting soil has time released ferts I believe... I am feeding every water and the first feed was at was 200ppm... plants responded so I increase 325ppm..looked good inc too 425 looking good then light cycle inc. 24H along with increased feed in at 525ppm. They are thirsty this morning so today they will get a little flush with plain ph adjusted spring water with no additional fertilizer and I’ll wait an see how each one responds.
Thanks guy’s for taking the time helping me out and sharing your knowledge. I’m a noob farmerand all guidance is much appreciated.
Fair enough, a few last points though. Even assuming it has helped those growers speed up their harvest time and increase growth, did they provide any evidence that it was enough of a benefit to counteract the 33% decrease in lamp life, the 33% increase in lighting/electric cost, and the likely even more substantial increase in cost for a/c (or loss of crop due to heat stress)? Not trying to knock your grow, your plants look good enough that I wouldn't even be that worried. My a/c went out a few weeks ago (finally getting fixed on monday) and lets just say I have some seriously grande tacos that make your plants look normal. The small amount of curl in your leaves on otherwise healthy looking plants tells me that going to 6 hours of darkness will probably solve your problem (not to mention giving you all the other benefits I mentioned), especially considering that from the sound of it things got worse when you switched to 24/0.Researched that same very question here in-depth and with countless hours of reading 18/6 vs 20/4 vs 24/0 I came too the conclusion that growers who grow 18/6 swear by it and so did the ones who 20/4 and 24/0, The 20/4 and 24/0 growers claim too have had more growth than they did with 18/6 plus a shorter total overall seed too harvest with the 24/0. I originally went 20/4 in the belief the plants need sleep. I recently went 24/0 just too see how they would respond for the next couple of weeks before I switched too the 12/12 cycle.

please help bro, my plants look literally so similar to yours, exact same coloring and shit its crazy, first pic ive found that is exactly like mine...did you end up having russets? ive spent a few days tryna get the light and heat down and its not changed the slight cupping/tacoing on my plant, but otherwise looks great. I ordered a scope but wont be here till tm...please console me friendSeveral guy’s had that same conversation/ debate on cost vs harvest and a couple of growers who seemed too be very seasoned / experienced stood firmly by their harvest/cycle periods and quoted some cost figures and that brought too light the drastically differences in cost we pay for a kw in different parts of the country and the world. Could it be their strain’s geneticswas the key and not the light cycle.. idk but it was some interesting reading and food for thought.
I’ll drop them down too 18/6 starting tomorrow till 12/12 cycle. More rest and less heat certainly want hurt them as you said.
Thanks for the help.
