sir_isOanswered grow question 3 years ago Well, in terms of advice it's very difficult to say.
It looks generally healthy, if stunted/small, aside from those burnt tips (have any ideas what that was from?).
But yeah, you should basically just be using fair levels of whatever bloom nutes you've got, perhaps look at simple things like lactic acid bacteria (milk, yoghurt, cheese sort of stuff). You can gradually feed your plants low levels of that.
Cheers and good luck.
