Sorry I deleted and read the post now. How many fans do you have? how close is your light? what size pots? does humidity dip at all?

Personally I think it's a combo of too much wind and the tips of the plants burning and the weird discoloration lead me to think too much light as well. I would lower the fan speed/wind and the intensity of the light/raise it.

How often are you watering? Well definetly too much light then. maybe humidity if its not the fan? And just a guide for the fan your plants should barely be moving . @Moshmen you think the size of his pot has anything to do with it? im just trying to think of every possibility

Three times a week is alot - overwatering is really watering to often. Do you water to run off? You should wait till those pots are light to lift . There’s a great article that Aquaman wrote here somewhere.
Are the post on a cold floor ? They look to be directly on the tent bottom it’s beneficial to be able to get air under those pots via lifting them up a couple inches should be good.
Back to the food how much are you feeding ? Do you use a ec or ppm meter or go by the bottle recommended amount?

I have grown OG Kush Auto 3 times now and all three times they showed similar signs at around the fifth week. I think they have a hard time with the change in nute requirements. I just hit them with cal-mag alone and backed off the feed a bit for a week and it sorted itself out.

IMO autos are lite feeders and do better on a well balanced diet , not switching the combo up to much just my experience with autos- I run pure blend pro grow thru the whole cycle just back off a tad at the end

Every strain is different - with the autos I use a grow based nute all the way thru harvest when I see preflowers I may add a little epsom salt ( 1 gram per gallon ) especially with the purple strains

with photo plants I lean on the grow nutes as well but transition to bloom nutes at the end of stretch I wish I was more technical for you but I’m kinda a grow by the seat of pants guy I try and read the plant a give it what it needs as I run 6 /8 strains at once right now - pain I. The ass ! Lots work - I’m currently transitioning to rockwool in a room with clones for consistency. Much easier style grow for sure
