Grown in coco, nutes im using are can a a&b temp is 27 celcius, ph is 6.4 and I am using bottled mineral water. Just read some more do you think it could be calcium deficiency?
I have check the calcium content of the water in my area and it is 150mg/L whereas my bottled water is only 3mg/L. I have mixed half of my bottled water with half of my tap water to level out the ph as the ph in my area for tap water is 8-9. Should I wait for my soil to dry before watering now?
