What is the temperature, EC and pH of the reservoir? What is “MC“and “mpk”?

What is “MC“and “mpk”?

MKP is Mono Potassium Phosphate (I use it for several weeks in flower, never in veg), and I assume MC is Mega Crop.

Yes but it was MPK. I thought maybe something else.

LOL. I had a moment of dyslexia. You're right, OP did say "mpk".

65-70f temperature rez.
ec 1.7-1.8
ph 5.8-6.0
Humidity 60-70%
and is it good that the windmill blows on the dryer
I suspect it's a humidity problem, give them a haircut
Monopotassium Phosphate - mkp 0-50-30
MC- mega crop

Ps. Defoliation? Sulfur burner? Oil neem? Epsom?

My dehumidifier takes 1 liter has 2 hours.
Or maybe the problem is that the water pump runs 24h
