Sick Plant Brown/yellow spots on leaves
Noticed these spots on the leaves. It started with the oldest fan leaves and I thought maybe they were just dying off. It has spread to more of the largest fan leaves, but none of the newer growth.
GH Flora Trio, Calimagic, hydroguard
Fresh nutes EC 1.1, before change out EC 0.7.
Hey man, how much cal/mag are you using? ml/gal
The nute schedule I'm following calls for 1tsp per gallon Too much calcium? The other strain is loving it ☹️
Perhaps it's a bit much, a tsp is 5ml, I usually use 2.5ml pre gal. Your Micro has cal/mag in it, and then your putting another 5 on top of that. My plants are living on a super model diet, two more weeks till chop and I've hardly hit an EC 1.0 this entire time. Your feed could be a bit aggressive. I'd flush with straight PH'ed RO water for 2-3 hrs then bring your nutz back in and cut the cal/mag in half or more. Raise by adding grow only, even if you have to remove a gallon, add grow to it and pour it back in.
I just did a fresh batch of water/nutrients and did about 3ml per gallon. If that's still too much I'll grab some more water tomorrow and flush and start over.
Yeah your spots say calcium deficiency but you've got cal, and your in the right PH. That where another excess could be causing the problem. and the only two could be P or K. imo still not an answer though.
