Ok so this is my first grow and it started off a little rough... I was using a shitty day spot lamp for the first 3-4 weeks of growth and now it is week 5 going on 6 and my plants are tall (about 8 -10 inches) and are not very full at all. I have them proped up and am hoping that now that i have gotten a good 400watt mh light that they will start flowering better. Its only day 3 of them being under the new light and i already see the leaves getting bigger and growing new ones, but im still worried about the height and that I need to keep them proped up. Should I cut the main steam to make them shorter and less top heavy or leave them as be... or is there anything anyone would sudgest?
