answered grow question 5y ago
can be a cal mag deficiency, but before check your ph (has to be something like 5.8) and the power of your light (too close/ too much power etc)

I think it was a cal mag and everything else too. I believe I was just under feeding them. Thanks for the help

Leaf spots
Hi I started seen some spots in one of my plants. The PH is 6.2, water temperature is 24.6°C, nutrients are 1ml/l of Grow/Micro/Bloom/Calmag and 2ml/l of Voodoo Juice from AN. I increased the nutrients to 2ml/l. No signs of root rot. Anyone experienced the same issue? Thanks you!

Leaf issues. Lockout? Need to Flush??
Leaf issues started showing up in 2 of 3 plants, progressing fast. Soil runoff tests have been v. high (2000ppm+) so we're assuming it's a lockout issue. We watered 1 day ago, with 200ppm solution so pots are still very wet. Better to let them dry out a bit or flush right away?

Early signs of Calcium deficiency?
See a deficiency here? The whole leaf is very mildly spotty, like just a shade off... seems to be getting worse but very slowly. I had to filter the pics I took, were over exposed.

Was hat meine Dame? Es begann mit einem Magnesiummangel und mittlerweile wird es immer schlimmer. Könnte das Kaliummangel sein? Bisher habe ich ihr ein wenig BioBizz Calmag gegeben...
