8 weeks, day 19, 8, 6 update: everything going good for most part. 8 week olds handled the feeding of the 9 ml of bio bloom well. So fed them 15ml today with photo plus and big bloom to see what they can handle. the young,s just haven't got the growth like they should at their ages. so I gave them sow photo plus, big bloom and some very low strength nutrients.see if it kicks em in gear.
