What’s up growmies really need some help in seeing if anyone knows whats going on with my girl. Strain is Sunset Sherbert from Zen Labs in San Diego Ca. Running a Mars hydro tsw 2000 at 18 inches above top of canopy at about 75% power. Everythings been going good till right now about 4 weeks into flower. I top dressed about a week before plants went into flower with mostly P-K and a little bit of nitrogen. I thought it was light burn since where the majority of the problem is at but it’s par at 75% is around 800-900 at 18 inches. I think it might be the root soil PH but not sure. Have any questions let me know thanks y’all.
