Auto Leaves twisting at start of bloom

[willytitan42]

I have 7 plants. All autos. All look perfect except one. Im on day 39. All just started to flower and white hairs appearing. Humidity 48% Temp 75F. I have box fan blowing at bottom. They all have been semi lollipopped. Cut away anything liggt will not penetrate too. I have 4 under philizon 3000w and the other three at edges of the philizon have two 300w viparspectras. The one im having problem with is on the outside bc i thought it was the cobs on the philizon but still hasnt recovered. I feed once or twice a week with tap water AN and a few additives: cal-mag, koolbloom. Im at 1/2 strength now at the last feeding being the max of 778ppm. Water runs at 100-140ppm before adding nutrients. This one is a Zkittles auto from CKS. Im thinking of flushing but flushing autos really hurts their growth more than anything ive done in past. The container is a deep 7 gallon but i have two others and n 7s. Im thinking its the soil bc i used what was left from peat moss, potting mix, ffof. Its really dense. So are the other two and look fine though. Thats all i got. Please help and thank you. I can add more photos if requested and needed to help.

Looks like nitrogen burn to me because they also are hella dark green. Or is that the lighting?

Research clawing cannabis leaves. I think thats the term. Water mould can also show these symptoms of twisting

Thanks man. I do think its the roots bc of the mix and the big pot its in.

You don’t need cal mag when using tap water and most nutes. The only time might be 4-5 weeks into flower.

As it is on the newest leaves, I'd say it is a deficiency or toxicity of micronutrients.
It seems toxicity of sulfur or manganese. More tending to be the 2nd one.
Flush ya plant.
This also happens when my flowers are too close to the light bulb

I didnt want to flush but ill do it. I did throw in GH micro on one feed so i think you are spot on.
