Red pure cbd auto overdose or deficiency

[arbunik]

Hello. please give advice

I grow "red pure cbd"

In DWC

third week of flowering

t 21-24 C

Ph 5.8-6

Ppm 550-450(actively dropping ppm, per day by 100)

Nut - Advanced Nutrients perfect ph

Grow/ micro/ bloom 1.3 ml /L

Big bud 0.7ml/l

Calmag (GH) 0.3ml/L

 

looks like a lack of calcium or potassium, but I slightly increase the dose of basic fertilizers G / M / B to 1.5 / ml / l the situation is getting worse.

or is it a toxic burn, but on the other way the fertilizer not so much

 

Can be that this strain very sensitive for nutrients or I am wrong? because other strain is ok and ppm is higher than red pure
