Constant nute burn @ Low EC

How come you just didnt use your calmag?

I figured it's overkill since hardwater micro already contains 42mg/l. I'm using 45l of soup with 60ml of micro. When I start my next grow I definitely will use the calmag but I've just switched to flowering so this grow is nearly complete. Would rather safe the bottle for the next grow.

This is how they're looking now, in case anyone is still interested
