Hope you guys can help me out on this one. My plant leaves keep getting yellow with a burning upwards.
After a lot of research I identify this as a cal Mag def. But its been 3 weeks Im feeding her with cal mag and those leafs dont stop to show up like that.
Here is more information about my grow.
Strain: Royal Queen seeds (Euphoria CBD)
4 weeks since flip to 12/12
Temps: 23 - 25 Celsius
Humidity: 65%
7 Liter pots
the last 3 feeds in august was:
14th: 150ppm calmag, 450ppm flora nova grow. Total: 600ppm. Ph 6.4 Runoff: Ph6.0
20th: 220ppm calmag, 300ppm grow, 200ppm bloom total: 720ppm.
25th: 270ppm calmag, 330 grow, 400ppm bloom. Total: 900ppm. Ph 6.6 Runoff: Ph6.1
(Im using RO water that comes out 3ppm only) and Flora nova Series
I notice that the runoff ph is always getting lower. maybe this is the main problem?
Should I give her more nutes?
