Ph problems maybe?

Looks like a ph issue. Do you know your soil ph and the ph of your water going in. Im gonna guess that you are feeding every other watering?

Hi, PH water between 5.8 and 6.5. Soil pH around 6. Yes feeding every other watering.

Hi, PH water between 5.8 and 6.5. Soil pH around 6. Yes feeding every other watering.

So this is all too low. Soil ph in veg should be 6.5 and in flower it should be 6.8. But this problem is caused by varying ph. So lets try and figure where the inconsistency is coming from. Are you ph'ing the water after you are adding nutes? Are you waiting a bit for things to settle, either the solution or your ph up, before getting the reading? Is the soil reading you got coming from run off or a soil probe?

Hi, I brought up the pH as suggested, and added a little more calcium and Epsom salt. They recovered perfectly. Thanks for the help guys. Much appreciated.
