I "assumed' he was using Cal Mag since he said he was following my nute schedule. If not using it Biggins, Stinky is right.....start asap.
Weedhound Reviewed by Weedhound on . Help me Diagnosis through my pics! Grown hydro in higromite. 5 weeks old. WeedHound's nute schedule. Switched it to 12/12 today and put in 1000w HPS. About 16" from plant. Spray to runoff with Liquid Light everyday. Using RO water. Went away for a few days to visit girlfriend and left someone else in charge of plants and came back to leaves curling up and brownish spots. Not sure if its overwater or nute burn. Rating: 5
