Indoor Bag Seed Grow

GrowGeek814 They are both doing great and responding to there first feeding of nutes well. I'm using organic molasses as a cal mag substitute and sweetener also I have intruced Superthrive but plan to stop feeding it before going into flowering. I plan to top these plants multiple times each but will wait till they have atleast 5 nodes. Also what is your opinion on finishing these photoperiods in there 3 gal buckets if I want a large yield? Seeing as this is my first real grow any help is appreciated. Thanks

GrowGeek814 The largest plant is doing well but I dont get why they it's not growing taller but yet so wide. The medium plant seems to be progressing slowly but healthy and well shaped, and the smaller ones are coming along. I continue to gradually increase my nutrients each weeek then see how they respond. These are under 340 watts of flourescent lighting thats on a 20/4 veg cycle. The oldest plant here is about 28 days from germination. Would like to top soon but want them to get taller. Tips and comments are appreciated. Thanks for looking.

GrowGeek814 Day 35 from seed. 2 large plants have both been topped and defoliated. I'm trying to mainline one of the smaller plants for my first time. They are not showing preflower yet but I think the large plant could very well be male and hopefully the other is female...wish me luck I will update again next week.
