1000 wt flood & drain flower!

4 plants under 1000 watt mh for veg & flower(just an experiment) and the plants are in a 2x4 flood and drain. watered four times daily with lights on. they are about two 1/2 ft and are very bushy with multiple bud sites but buds are very small. they are in 4th week of flowering, is this because of mh or has growth not had enough time. are buds supposed to be big in the fourth week or not really. they have a lots of white hairs though.help please!!!pics not available but any words of wisdom would suffice.

You are on track. They stretch in the first 2 weeks. They then fill out slowly and then the last 2 weeks they explode with growth. They will fatten up. Ya got 4 more weeks or so.

ya man best way to look at it is the first 4 weeks is all growing branches, forming sites, and expanding roots.. next two weeks shapes the buds and colas, and the last couple weeks is just filling them in, making em more dense and gettn fat n resinous
