Robertsanswered grow question 3 years ago Ok so what I see is a ph issue for sure in substrate. Depending on what your growing in. If soil 6.3 to 6.5 should be good. not my preferred method of growing. If in a hydro soil or coco, 5.8 in vegging. You are experiencing ph lock outs of several nutes. So I am going with ph issue for sure. Good luck and happy growing
