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

Hi Arbunik,

I am also cultivating a Red Pure CBD auto but outdoors and also noticed this strains is more sensitive to over nutrition

My strain is full purple, she is beauty but it makes it more difficult to detect insufficiencies or pests… noticed the crickets love them leaves of this plant over my Dark Devil’s 😅
