They definitely look a lot better but they are still small for a month and a half, but they were stunted in the last post so this progress is good! Just know that the next time your plants will grow to this size in just a few weeks rather than a month and a half. If you veg them out long enough, sure you could fill it with 5. I'm growing 4 full size plants and one mini plant (it was a clone i took from another plant as a test) and i have a 3x3 which will probably fill up mostly the tent and i let it veg for 6 weeks. They have been 12/12 for about a week now. I did a sorta quadline on the big plants and spread them out horizontally before i flipped to 12/12. Oh and im using 3 gallon fabric pots (one gallon for the clone) and a 315 LEC.
Im no pro but maybe seeing a 3x3 will help you plan for your 4x4. I wouldnt' bet on filling up the tent this grow unless you plan to veg these out and train these for a little longer. Especially if you are planing on having 5 plants. The more you grow the easier it will be to train and get that full tent canopy. My first grow was all over the place but now its easier to get the plants to do what i want and i can visualize better because i have a better understanding on how this plant grows. And that only came with experience. You're on the right track though. They look healthy, although it's hard to see any deficiencies with the purple lighting.
PS SORRY FOR THE LONG POST!!!:doubtful:
