Glookies!

Hi! Like burmese said, it's normal for this stage. You can see how small the stem is where the leaf emerges and to how wide it's getting so it's kinda like stretching at thew moment. If those leafs were fully formed and then canoe upwards, it could be too much heat/too low humidity

Hi! I've checked your feeding schedule and it looks right to me. I don't think that is a PH or overfeeding problem. Can you check the EC of the water b4 adding the fertilizers? If you can do that, you can see what kind of water do you have. If you have 200-300ppm water, it could be CalMag deficiency wich turns yellow some young sprouts/leaves. Biobizz have CalMag solution wich is also organic. If you can't check your initial PPM I would recommend to check the website of your area (only check the water info of your zone) and you can get an idea of your initial PPM and know if it's a CalMag deficiency.

That is nutrient burn. Basically that´s the plants saying that they have enough nutrients already. In that case it´s very normal, just hold on the nutrients one or two waterings and then put on the nutrients back. in schedule. Or you could flush I you feel like so or if the case was way worse than that. Peace ✌️
