I did the runoff and the yellow water gave me a yellow answer (correct Ph).
I've reduced again watering (once every 2-3 days) and I hope the girls won't complain.
I will transplant to larger pots as soon as I buy them, this is my 1st grow and I still lack some material.
The ferts come from Europe. Wortel from Bcuzz is a root stimulator (no indications about the composition) and TNT complex from Hesi is a NPK fertilizer (6+2+4 means, I think, 6% Nitrogen, 2% Phosphorus and 4% Potassium)

I think I'll just take this plant away. Too bad we can't know its if it's a female.
Anyway, thanks for the advices.
