I have 2 White Widow and 3 Sour Diesel. I'm at about week 6 in flower. Growing in peat and perlite (70/30). I feed them with grotek nutrients at a pH around 5.8. I'm running a 600w diy led fixture with Samsung leds 3500k in a 4*4 tent.
In the last week they started showing this symptoms, could it be underfeeding? PK deficiency?
Thanks in advance!
