[sa new grower]

HI all im havin fun with my first hydro auto grow have some 2fast2vast in perl/verm mix using gh 3 part plants are about 5 wks old with preflowers showing at the tops would it be about the right time to move to the bloom ratios ?

I could tell better with a picture but it's better to hold off on bloom nutes until you see numerous bud sites forming pistols to start bloom feed.

I use GH's Flora 3 part as well. You should be using all 3 parts GRO, MICRO and BLOOM pretty much from the start. I think I start adding BLOOM to my mix around 2 weeks in. The MICRO is VERY heavy on nitrogen and I cut out the GRO around day 25'ish. Results of this method on a Crape Crinkle in a 3.5 gallon bucket, 71 days sprout to chop.....
