At the end of this grow I will list the schedule I used. I'll also list how the nutrients affected the pH of my water.
Water pH = 8.1
Week -6 plain pH water
Week -5. Plain pH water
Week -4. 2ml grow a & b, 1ml take root, 2ml multi total, 0.5 cal mag = solution ph 6.9
Week -3 2ml grow a & b, 1ml take root, 0.5 cal mag = solution pH 6.9
Week -2 2.5ml grow a & b, 1ml take root, 2ml multi total, 0.5 cal mag = solution pH 6.6
Week -1 3ml grow a & b, 1ml take root, o.5 cal mag = solution pH 6.5?
Week 1. 2ml bloom a & b, 1ml take root, 1ml multi total, 0.5 cal mag = solution pH 6.9
Week 2 2ml bloom a & b, 0.2ml explode, 0.5 cal mag = solution pH 6.7
The above is from this and my other euforia grow.
Tempted to stop adjusting the pH altogether. If the soil pH drops through the grow perhaps these higher values would be better. Either that or just add one drop of pH down to bring it under 6.5............
