Robertsanswered grow question 3 years ago Your ph is getting out of range in your soil. You are experiencing nutrition lock out. You soil ph run off should be around 6.3 to 6.5 in soil. If off, you need to run ph water through till desired and acceptable ph range. If way off that is. if just a little off which I think you are you can solve with a heavy watering of right ph. Depending upon direction up or down you need to go. You should also always have 20 percent run off and test it for ph and TDS. To know what is going on in soil. Good luck and happy growing 🌱🌱🌱
