Give us some Info on grow. Nutes used, feed schedule, lights, whats your ph, have you fed any calmag? With more info you willget more help

They have been fine for four weeks by Same routine. Same nutes(ionic) using two 600w and not using calmag

From the research I've done it looks like a ph problem so I might just take all the water out and start with new batch of clean nutes. Usually sit around 6.5

First off problems take time to develop so just cause it seemed out for a few weeks doesnt mean thats not when problem started. I would add some cal/mag and check your ph
