Does anyone know what can be causing theese marks and stains on my leaves? View week 6 for pics.. its on the top leaves mostly. Water 5l per plant every other day. Ph at 5.7-5.9
Calcium excess gives those white spots on leaves, reduce the cal-mag dose. 1 ml/lt is I believe around 0.5 EC (250 PPM), get it below 0.4 EC (200 PPM), I would try with 0.3 EC (150 PPM) worth of cal-mag, see if that helps. The spots will not go away, but no new leaves should be affected.
