iHigh Posted May 23, 2020 Share Posted May 23, 2020 Hi Please help - 3 rows of 3 pots. All a local cannabis craft soil. I have been feeding low doses of Biobiuzz nutes & stimulants through a Blumat drip system. Strain is a Purple Punch cross, ( that needs extra cal/mag and I gave a bit ) . The first row is airpots - and everything looking healthy and green 2nd two rows - locally made fabric pot - bottom big old leaves have turned a pure yellow ( now forming brown patches ) - no curling , no leaf tip burn - and newer leaves are a pale green . Difficult to see in pic one - but right two rows are the pale green ones. I narrowed down to a lack of Nitrogen, ( from what I can research ) so I have given a good feed of BioBizz fishmix. Question is - is this lack of N and why only two of the three rows with cloth pots ? Lack of O2 due to fabric maybe ? PS...There is a knat problem - but not too bad - they came in the soil Please, any advice appreciated 1 1 Quote Link to comment Share on other sites More sharing options...
SkunkPharm Posted May 23, 2020 Share Posted May 23, 2020 It looks good. I would not be to worried this late into flower. As long as the upper leaves dont yellow. Take off the leaves as they go completely yellow. 2 Quote Link to comment Share on other sites More sharing options...
