Any idea what's going on with my plant here getting rust like spots was on 1 leaf yesterday is on 2 now she's had no nutes as she's in bio bizz all mix all I gave yesterday was 1.5ml to 3l water of cal mag temperature has been fluctuating from 20c to 28c she's under viparspectra
Hi guys will lower the pH slightly yes I have ph testers but all need calibration as new and can't find my de ionised water to do it🤦♂️ she's looking a little better going to give a very very light feed tonight see how she responds
Beginning manganese deficiency.
Darker veins and brown -soon- necrotic spots are clearly visible.
Adjust pH, rather to the lower range.
If that's not enough, apply manganese chelate.
Good luck!
Possible calcium defeciency, so you did the right thing. I would personally think about adding nutes at a very low dose and possibly raising the light or dimming it a bit 👍🌱
