hello, i have (in my opinion) nuted quite heavily. at least every two days. everything went fine until i topped the plant, then this happened when i nuted normally. Ph is 6.0 and has been all the time so it shouldnt be a ph problem. i dont know what the strain is. probably herijuana or anesthesia. i grow in hempy buckets, shouldnt be from under/overwatering.
Hi there, looks like phosphorus starting to lock out maybe, if it starts yellowing and getting necrotic spotches & red stems, lower your ph to 5.6-5.8, hempy's go by hydro rules, P locks out at 6.0 and higher. Good luck!
