I would appreciate all comments and opinions and w...

I see what you're doing but wanted to let you know that you should be quite careful mixing and matching so many different additives and nutes brands... take it slow is what I'm saying, sometimes their nutes aren't always compatible.... Anyways, i see your lamp to plant distiance is really a bit close, your plant is about to do a veg stretch so careful not having the lamp too close. Beyond that i see you've really onboarded everyone's comment, so that's good. Good luck !

@BudHaks Hi there! Your pH is not acidic enough for your coco medium, try to stick in the optimal 5.5-5.8 pH range, this will help your plant to handle nutrients intakes. Managing pH and EC is a must, especially in soilless setups. I guess you're not really in a hydro setup since you're doing hand-watering, so I'd recommend not to overwater the container, mediums (even coco) must alternate between dry and wet phases, in order for the roots to search for water and spread. Your coco should never be 100% dry, but on the other hand it shouldn't stay 100% wet for too long, I think your seedling is suffering from too much humidity in the medium + in the air, roots can't breath and this might lead to deficiencies and/or nutrients lockout later. Now about the seedling stretching, it's probably because of the light-plant distance, which is weird because if your distance is 7cm you should be fine. It could also be the opposite: if the plant-to-light distance is too short, heat might be responsible for the plant stretching. Are you sure your light is not too far neither than too close from the seedling? About the nutrients, Coco by itself has nothing to offer to the roots, so you must add very light doses of nutrients in your waterings, or you may encounter deficiencies very quickly. Roots-stimulator and Nitrogen is all she needs at this stage. Since you're growing an autoflowering strain, don't follow the manufacturer's feeding schedule, start with 1/4 to 1/3 of what they advise, then slowly increase doses if plant is healthy / reacting well to nutrients intakes. Hope this will help, keep us up-to-date and happy growing 👊

In additon to Spinner Grow i just would recommend you to give her very soon an new bucket. Automatics are tricky, if the roots hit the ground they stopp growing and in worst case they start flowering. If you like nice and big automatics put them aftergermination in her final pot with prefertilised soil
