They are at 85 with my leds on and 75 in dark period but I won’t lie my RH has been Low like 27 I just got a bigger humidifier I wonder if RH could also cause this
Shouldn't be an RH issue, in the winter I use ventilation to cool my flower room (~5k of light) and my temps range from 70-88 depending on the outdoor temperature, so they fluctuate similarly to natural summer days. Due to the air flow, though, the RH is consistently 18-30% with lights on.

Its locked out from feeding too much nutes. Im the king of that.

Best to flush her and leech out all the salts left in the soil.

Also... you should flush out the soil once a month. So if youre vegging 8 weeks you should flush half way through. Then again before flipping then again about 1 month after flipping. Should be good after that.

Organics. No salts, and flushing won’t work very well.

Yeah if it's organics the only thing flushing will do is encourage anaerobic bacteria to flourish by limiting the available oxygen in the soil. Sorry for my confusion, I was under the impression Fox Farms is a synganic similar to Botanicare.

Sometimes tap water can be hard with ppm uo to 900. The buds look fat tho and if it was locked out because of your water i dont think they would have got that big. Its something you did within the last two weeks

I’ve been feeding her my local supermarkets RO gallon water bottles the ph always comes out to 5.8 and then I would add the nutes to the gallon 2 tablespoons per gallon and it suggests 4!

They don't look like they have PK toxicity. I really just think next time you should add a ml or 2 of Calmag to that RO, Calmag to push through stretch. Besides the early fade, it looks pretty good to me.
