GP, I'll get to your question, but wanted to give an overview of my grow "techniques" as a comparison to what others have posted.
My soil (Pro-Mix HP, EWC, minerals) is Doc Bud's High Brix Mix. Doc's Nutes also. My lights are Fluence Spydr X, and ACInifities Iongrid T24. Once sprouted seeds go into either Solo's (in the case with this BAM) or straight to 1Gal. I usually skip Solos and go straight to 1s, but had a space issue.... I top between the 4 n 5 nodes, waiting for a good gap so I can leave a stump on the main stalk so it heals off properly. I'll tie the branches down as they lengthen keeping 4-6. I do two weeks of "germination" by which times there's 3-4 nodes, then veg is typically another 4 weeks, depending on plant size, I or S, etc. I do a major pruning at transplant into 7s. Then light pruning weekly. Once grow tips hit the edge of the pot I'll typically stake them, tie them off, and encourage straight up growth. Day 21 of switch they get their final major pruning leaving 3-6 nodes above where they attach to the stake. I also do a defoliation of major fans. From then on its cutting off suckers, leaves blocking bud sites, etc. I work to keep the center of the plant open so light hits the soil as well as getting more light to the inner buds. I've found this method keeps plants accessible for pruning, feeding, inspecting, etc. And, I'd rather trim 4-6 large colas with big buds than a gazillion smaller colas/buds. Like many, I grow for quality rather than quantity. I typically get around 4 oz per plant.
To answer your question about vegging BAM:
• seed went into solo on 1/7
• seed was above ground on 1/11 (+4 days)
• Tp'ed to 1G on 1/28 (+17 days)
• Tp'ed to 7 G on 2/17 (+21 days)
• Today, 2/28 is Flower week 2-Day +11, 53 days from seed.
So I germinated for two weeks and vegged for 3, or some would say, vegged for 5 weeks.
Here's a couple of pics from this morning. Compare them to my previous pics taken on Sunday.
