Hi guys
So I'm growing three plants that are currently in 2-3 week of flower.
I'm growing them in a mix of cocopeat, vermiculite and Perlite and feeding with General Hydroponics 3 part nutrients
Feed them every 2-3 days, basically whenever the pot feels light.
Decided to check some PPM/PH readings and noticed that : -
1 - PPM of nutrient solution going in: - 900 PPM
PPM of nutrient solution run off : - 350-400 PPM
2 - PH of Nutrient solution going in : - PH 6
PH of Nutrient solution run off : - PH 7-7.1
Till now I have not had to check these readings because my plants looked healthy without any symptoms of deficiency. But today I noticed in two of my plants the lower leaves were starting to lose color, and some leaf tips becoming brown, drying, and pointing upwards.
After reading through a lot of problem guides, I figured the symptoms indicate a possible Mag deficiency so I fed them today with an added dose of some Advance Nutrients Cali-Magic for mag supplement.
Am I on the right track?
Is it okay to water every 2-3 days or should I be watering more frequently?
Is it okay for the PPM of run off to come down 350-400 from 850-900 going in?
What about the PH of runoff coming out higher than going in?
Can someone with experience guide me a little on this?
Thanks a bunch!
