I would cut back on the nitrogen. I tried using the GH formula and got rapid growth on stems in just four hours. That's how fast it works. Try the lucas formula, which doesn't use the grow green bottle. For veg cycle use 5ml micro and 10 ml B. For flower use 8 ml micro and 16 ml B. Your seedlings look a bit stretched, too much nitrogen. There's plenty of nitrogen in the other two. The dark veins with yellowing on the edges looks like magnesium deficiency. But I would adjust take out the nitrogen first and see how it goes. Different strains have different sensitivity to ferts. Hope this helps.
