Hiya
Having a real rough time with my 2 girls at the moment.
This is an AK59 auto in dwc under a QB288 135w basic board. Temps and RH are ok i think. Shes been getting Canna A+B up to about 700ppm in the bucket but shes starting to look hungry. Had a look at some pics and Mg deficiency looked the most similar.
Can anyone confirm? And whats the fix, i was thinking Epsom salts foliar feed?
Thanks!
