Potential polyploid, Super Long GG4 Sherbet FF Grow

Day 9, week 2: The first set of fan leaves is unfurling, so I am expecting growth to take off this week. Currently planning to transplant at the end of week 3. I added a dollup of raw honey to the half gallon jug I bottom feed with. I fill the jug and let it sit overnight to let any sanitizing agents in the water evaporate. Day 11, week 2: She is significantly firmer and wider than yesterday. The fingers on her first fan leaves are fully visible, and her third growth node is clearly visible from the top and sides. Since she has months of growth left it's super important to keep her compact during this early growth stage so I can continue giving her enough light until she gets outside. Day 12, week 2: I went to check her roots today and was shocked to find giant fingers sticking through her bottom holes. I transplanted her to a 12 inch round pot and gave her a light watering with some water I ran through her previous soil mixture. The pot is completely full of rich compost from my backyard compost heap. It's the same stuff she was previously potted in. Hopefully this boost of new natural nutrients and microbes will help her use those giant roots to gain explosive growth! She now has more than twice the light she had previously. I'm still keeping it an inch away to avoid as much stretching as possible. My plan is to use aggressive side lighting and minimal close top-lighting to keep her very bushy and growing outwards, so when she goes outside she can explode upwards. Day 13, week 2, I am noticing slight yellowing on the bottom leaves of this and another plant that was in a different tray. I've scoured the internet and it's either nitrogen deficiency or nutrient lockout. However the other plants in the same tray did not display this stress, so it may be strain-specific nutrient needs. I'll keep you updated. Day 14, week 2: She seems stable and firm, and growth has continued on her newest set of leaves. The 2 plants with nitrogen deficiency are significantly worse today and they are both the same strain, so I'm thinking I was just paranoid about this lady.
