Trying to figure out if this is lack of nutrients or nutrient burn .
A pic of the whole plant would be helpful.
Can you please tell us how old is the plant, is it in flowering, what soil are you in (brand and type,) and what and how often do you feed?
If you know your runoff PPM and pH, that would be helpful too.
This is the info you asked for,feed maybe once a week.
It will be 12 weeks on the 18th of july and it is white widow A/F
That is all quality stuff. I would flush the soil to eliminate salts and high PPM, and then resume feeding at 1/2 or 3/4 strength.
The overall plant looks okay.
Ph stays steady at 7
Thanx,appreciate the info
