Help pls!!! something strange is happening

I looked at your diary your plants are in coco. I have a lot of experience growing in coco. You have a magnesium deficiency. Cal mag is needed with growing in coco. Also your ph is very important 5.8 in 5.8 out in vegging 6.2 in 6.2 out in flowering. Coco needs to stay wet. Not sitting in run off though. Your nitrogen level looks pretty high as well. Vegging npk ratio 3-1-2. Flowering npk ratio 1-2-3. Coco does not dry out and you can not over water. Just don't let it sit in runoff. I feed my every other day, and splash ph water on them between to keep wet. Coco is hydro in a potter. So lots of water used. Good luck. Feel free to hit me up if you need more help. 🌱🌱🌱
