When i add Cal-Mag ec goes 3.0 i think 3 is too high? Can someone verify that for me, I don't see burn at leaves so it might be ok? There has been long time some brownish color on 2 leaves but they are oldest leaves of plant and have had those many weeks even ec was too high. Or should i drop come nutrient amount or what should i do?
Everything is still going good and now the stretching is starting
The Browning looks like a nutrient deficiency, PH is too high for coco should be between 5.5 and 6.2 with 5.8 regarded as the sweet spot. The ec is also little high 1.8 to 2.2 from feed charts.looking back through the veg stage in sure by having such a high ec and PH, the plant has nutrient burn and locked out.
