Thanks for getting back to me.
My troubles start in flower. Using AN two part. Light is 600 HPS in a closet with good extraction. Temps are low 70 at pot and 80+ at tops. I know I'm having a drainage problem as it is about a week between waterings (let dry out then soak till a little run off). Going to try 50/50 promix & perlite. I'll get back to you on next grow. Got some vegging now. For now, just wondering if an alkalinity of 80 in soil is a potential problem.
