The Grow Must Grow

I can't believe I'm actually growing, so far, so good, and honestly, folks, it's all bc of the community here. Your guidance, advice, and detailed explanations are what's gotten me this far, so THANK U. I finally transplanted last Friday, 1/8, planting each gal in a 50/50 mix of Happy Frog & Ocean Forest soils, thoroughly mixing & pre-watering prior to and after transplant. Snipped cup edge & ripped plastic of cup slowly, so as not to cut or break any roots. Popped out beautifully in 1 piece, all 3. As u can see, it was more than time to transplant than, but I'd realized too late almost HF is good for seedlings, but not after that. I actually called Fox Farm Customer Service to discuss the soil issue, as I had 3 big bags of HD and wanted to put it to use. FF recommended the 50/50 mix, so that's what I did. Was able to transplant smoothly without disturbing any roots, as I listened to advice that suggested I skip a scheduled watering to keep the soil from coming apart. Re-configured entire tent w/the addition of 3 wrought iron plant holders that set up 8"in high above the tent floor. Underneath I placed a clear plastic bowl sufficient to catch 2+ quarts of water runoff from the plants. Unfortunately, unless my plant stops growing vertically, I'm going to have no alternative but to raise the height at least a foot to make up for the foot I lost using the planter, as there has to be room for the light to be of sufficient distance away and to have sufficient space to grow successfully. I also fertilized for the 1st time this past Sunday, uaing 1/4 of the recommended amount (per the advice of my mentor, the talented Bluntzilla ❤️). I'd made the mistake of snipping off the few yellowing leaves, but I have to say, they're looking pretty dang terrific RN. Seeing those roots, I can see that was the reason for those yellowing leaves; the plant had run out of room to grow. I must say, I'm very pleased with myself. Next, I need to build my SCROG, as I intend to do all that if I can to train them to grow horizontally, rather than vertically. I've heard only good things about topping and low-stress training & think I could do it successfully. My grow IS GROWING!!! THANK YOU SO MUCH TO THE GROWDIARIES COMMUNITY!!! PARTICULARLY YOU, BLUNTZILLA!! Your generosity of time and expertise reminds me there still are good ppl in the world who just want to help others and want nothing in return, and gives me HOPE! On to the harvest damn it!!!!!
