P or K deficiency? Calcium?

Nearing harvest on this one, it’s a Zkittlez auto in week 15 ( day 108 ). Medium is Royal Gold Tupur mix which is coco based. Tent runs around 75°F and low RH at around 35-45%.



I water usually water 2x a day and occasionally 3x a day following the General Hydroponics feed chart recommended ratios but at 1/4th the dose in RO water which is:
Emerald Harvest Calmag (2-0-0) at 5-6ml/gal.
FloraMicro (5-0-1) at 1ml/gal.
FloraBloom (0-5-4) at 4ml/gal.
Liquid KoolBloom (0-10-10) at 1ml/gal.

Going in my water reads an EC of 800-850, 550ppm and always pH’ed to 5.9-6.0.
My last runoff measurement was EC of 880, 600ppm and a pH of 5.80.

Started getting this on the leaves recently..

Should I increase the florabloom or the liquid KoolBloom or just keep feeding it like I already am? It should be ready to harvest in a week or two. Trichomes are still mostly clear, some cloudy and a couple amber.
I’ve also had a calcium issue with this plant as well as heat/light stress from the HPS 150 light I put in the tent right before flowering began.

I would let it ride out since you are close to harvest. Do you flush your plants? Might not be the best idea to feed nutes so late in flower it may leave your buds with a chemical taste
