nice work buddy not bad but with rockwool they tend to get over water so be careful check for roots on bottom to see if they go through if they do you are good, if not and with too much watering you will be drowning the roots with no oxygen(causing alot of F**king problems) cause that is the problem i'am having right now and i'am thinking it's all this other shit which it is too cause over watering cause some nutrients not to be absorb or uptake and there you go with the deficiency shit and you're thinking its some other shit which leads to misdiagnosed= killing it with kindness

O yea how i know it was over watering cause i had one my friends with 15 years on his belt and also owns a hydro store come over to check my shit, he step into my room and before saying anything he said i bet you 100 dollars its over watering and i ask how the F you know, he lifted my rockwool cubic up showing me the bottom which there was no roots coming out at all and on top of the cubic where the rapid rooters at you could see little roots trying to grow out.
