Gelato Auto

This can also be a sign of magnesium deficiency.

Thanks guys, At one point I did gave her a whole liter with nutes and since then I wasn't able to dry completly the pot. There seem to be a spot that wont dry in center bottom even after 8 day of not watering. Should I transplant it in new soil or it's too late? I try to irrigate it close to the contour with 300ml at 2, 3 days interval to not over feed. For my next grow I'll maybe add perlite or try promix HP and be more gradual in watering.

Both your temp and your humidity are too high for her.... I'd knock the heat down to the mid-70s at least if you can and the humidity needs to get down into the 50s... DON'T transplant this lady... she's an auto and that kind of stress will stop her from developing on her own time schedule - you'll actually be preventing her from going into flower... She would have zero time to recover! Good luck!
