Your plants are looking real good at this point. Nice going. Definitely use those big pots if at all possible. What are you doing for nutes? I'm really a KISS type of guy so I just go with MaxSea AP and Bloom. Works just fine, doesn't cost much and very simple to use. I feed probably every 10-14 days at 60% strength with AP until I see signs of flowering. I then mix AP and Bloom for a couple of feeds, then back to AP until full bloom when I move to Bloom. Still mix in AP every third or fourth feed so to keep the nitrogen available.It was in a 3 gallon pot outside. I have a 4 x 4 tent that I grow in and these are just to see what happens. This year they are 7 and 10 gallon pots and happy frog soil.
I like indoors a lot better but the sun is free. Tough call. And I learn with every planter pot grow on the deck. I get terrible sunlight on my deck because of trees but this year they are doing pretty good in veg.
I have a pair of 30 gallon pots I might pot up to. I need 4 more bags of happy frog!
