Can anyone help I’m not sure if this a magnesium deficiency or not? It’s mainly on the newer growth. I’m running a flood and drain system, 490ppm I’m at and ph is at 5.8 slowly rising to 6.2 before I drop it back down.
I’m just going into week 6 but this showed up almost a week ago thought at first it was mute burn so I dropped the ppms down a bit but they seem to be drinking a lot and feeding heavy so have raised them back up again.
