m0useanswered grow question 8 months ago Bio Bizz can be a good feeding regime, just get the complete lineup for growing in anything that is remotely soilless or you'll run into issues with calcium.
You can still easily overfeed on it. The origin of the compounds in the feed might be from "Organic" sources, however they are still readily available plant nutrients and giving to much will still cause plant burn. Same goes with dry amendments but they take a bit longer to breakdown, however you can not flush them out easily when you give to much.
Plant one is looking healthy, plant 2 not so much, might want to pop another seed. Aim for 1oz a plant "28g" if this is your first time growing then later on up that to 1.5 or 3oz.
Good Luck!
