Pineapple Express and white queen
Vegging 18/6 under 3500k and 6500k COBs
RDWC running between 500-600 uS (300ppm) and pH between 6.2-5.5 temps between 65 and 85. Have a chiller but during the day it's too hot for it to handle.
Using just ROed water, Dyna Grow foliage pro (analysis of nutrients in attached photo), SOS (beneficial bacteria) and Dyna Grow ProTekt
PH usually drops overnight to around 5.5 and I use ProTekt to bring it back up around 6
New growth showing yellowing starting at stem and spreading toward tips. Veins do not appear to stay green, yellowing is uniform. Some brown spots have appeared on lower leaves similar to calcium def rust spots but not many. Some new leaves also canoeing a little.
It looks like a potential iron deficiency but not sure. Could calcium or magnesium be interfering with uptake? Any thoughts appreciated.
