I've used FloraDuo nutes and have been happy with the results. I use their feeding schedule when applying the nutes to the soil. I use FloraDuo A, B, Floralicious Plus and Liquid Koolbloom, again according to the FloraDuo feeding schedule. Keep in mind that Promix soil already has a lot of nutes in the soil. I also use Promix soil and a 20/4 light cycle, although through the first 4 weeks 24/0 seems to work depending on the strain. I'm not familiar with your strain.
What watt is your led? Keep the led at least 16 inches above the plant for the first 4 or 5 weeks or so of the seedlings life. This allows the plant to grow nice and tall without burning the leaves. Adjust the led height as the plant grows. If the tips of the plant's leaves turn brown, then the plant is too close to the light. You haven't harmed the plant, she's just telling you that the led is too close to her and you need to raise the led.
You probably have some flowers starting by now. In week 5 or 6, when the flowers become more numerous, then lower the light to 8 inches or so above the plant. She'll stop growing around week 6 or 7 and buds will start to form, then the light can be lowered to 6 or 7 inches above the plant so as to focus on the buds. The buds will get really thick and when the fan leaves turn yellow, then stop the nutes and just feed her water for two weeks. Then chop her down and cure!
Check out the excellent stickies written by Muddy, such as the life of an autoflower. These stickies are in the new growers forum. These stickies are great!
Don't sweat the grow so much, just follow what I've typed and learn from Muddy as his stickies are the gold standard to learn from! People who have been growing a long time make it seem like growing is rocket science, but it isn't. After your first grow and cure you'll be giving advice like a pro because you'll then have the experience of a first grow. I'm only on my second af grow and I've learned tons from my first grow. Also you won't find a friendlier, more helpful group than on this website! For real! :High 5:
Happy growing! :stylez rasta smoke:
