hello from chong nonsi my thai brother ! plants only need two things water and light, that's the only nutrients you need. Think of nutrients like a target with a bulls eye you dont want to over do it or under do it, you cant really give more juice to get better results, you want to give just enough to get by. If you want to find some perfect nutrient line that works really well, i can confirm that this thai company is pure genius http://finedaysplants.com , get the full line up, cut the feeding by 50% you'll get great results. To get back to the light 11hrs is fine, especially with this heat these days. with autos many people try for 18hrs indoors because they can, and it accelerates the flower time. You can expect your 2 month auto to go to 3 months +/- one week. So to answer your question , no you can t compensate light with nutrients, even expensive ones. And be very careful giving any nutrients at all to a seedling. Best to simply spray something like Zweed from Fine Days once a day for the first two weeks. Hope this helps ! 🚀
