Hello.
Those girls are same clone in RDWC system.
Grow area : 1.5m x 1.5m
Temperature : 23-26 celcius
Humidity : 55-60%
Co2 : 1100 ppm
Light : Resina Q bar 700 watt
Light distance : 45 cm
Nutrients : Advanced nutrients connoisseur full line
Current EC : 3000 μs/cm ( i am not going to go higher than 3000)
Ph: 5.5 - 6.0
water temp : 20 celcius
I keep getting the same problem at this week of flowering. Beginning of 4th week from 12/12.
I change reservoir every week . I add Sensi Cal mag to RO WATER until my EC goes to 350-400μs/cm and then i add nutes.
I keep getting the same problem despite i tried different nutrient companies in the past ( GH, Remo nutrients).
The problem starts at the leaf tip creating small spots and spreading until leaf is like burned and crispy.
I am assuming it is light stress . any help ?
