I am growing in a wilma system, clay pebbles, now in flower, ph 6.1-5.6
ec 1.7 with a BG ec of 0.7

I was told this could be a calmag problem so after adding this last week, things are not looking good at all. I added 200ppm of calmag about 1ml per L

They are under a 600w hps about 2 feet away, temps have been 24 to 30.6 in the last week, although this started before the hot weather.

Res content

90l water

AN sensi bloom 220ml A 220ml B

60ml guardian angel

90ml Zyme

Right my friend I would say it's magnesium and calcium .has the problem appeared on any more leaves or are the allready infected leaves just getting worse also what is your humidity this can have the same symptoms if to low because potassium then gets locked out which then in turn starts to lock other nutes out calcium been first from my experience hope that helps fella
