PLZ HELP picking a couple of things

I currently have 5 6 weeks old Cali med. Plants switched to 12/12 at 4 1/2 weeks old . What I am wondering is, are they old enough to be fed? If so, which food should I feed them, Foxfarm Blooming one or tiger bloom? Do I just follow the instructions on the back of the bottle or what do I do?

Start them off with half nutes, you could have started like 3 weeks ago... I havent used fox farm or tiger bloom, but either would work. Some one will give you advice on the nutes.

What are you growing in? soil? Ocean Forrest?
Yes, you are probably overdue for a feeding. I would recommend you go to their website & get their feeding schedule for your medium. I use Fox Farm & starting feeding at 1/4 strength after 3 weeks.

no miracle grow moisture gro didnt have money for foxfarm and why is it so god
