How can i help the baby???

Run a base ec of calmag at 0.4 then ass nutrients on top

Imo, nitro excess is your first problem there.

Not 100% sure what it's lacking there. I looked through and noticed your giving 0.5ml/L cal mag. Try increasing it to 1ml/L.

Hello mate, I will suggest you to use a product containing cal/mag. This looks like a calcium deficiency or both cal/mag. If you are growing in soft water or R / O this is advisable. I personally grow in soft water and around 3 weeks I add a cal/mag formula to the water to avoid deficits during flowering. Hope I was helpful. Happy grow mate :)

Hi mate, that looks like a magnesium deficiency. You want to get yourself some cal mag. It does contain nitrogen so make sure you take this into consideration when making your feed. I'd also give her a little more bloom nutes just to rule that out as well. Hope this helps and good luck with the rest of your grow 🙂
