Turned on the flower setting of my GC4 and started adding nutrients.
Plant 1 looks absolutly perfect, while plant 2 started looking slightly unhealthy... (some leaf tips curling down). Well... i've tested the ph leves of my local tab water and noticed the water is to alkaline (8.5 to be exact), so i orderd some pH- by BioBizz.
Also plant 2 in particular grew into a very dense bush, i feel like i'm slowly running out of space and a lot of leafs dont get any light, so I'll have to do something about that.
