Stage - Seedling: Day 4
A little break in the temperature today. High will be 91° F (33°C) and the current Rh is 47%.
No water was added this morning since they still looked saturated and I am still concerned with drowning, even in Coco. Tonight/tomorrow I will most likely start a twice a day watering. All water includes the @Prescription Blend Core A and Core B nutrients at a ppm level of 150. When testing the PH last night it looked like it creeped low to 5.7. I needed to add some distilled water (PH 8.0) to bring the PH up which diluted the solution slightly.
Do you mix nutrient in distilled or RO water? If so then your pH will settle on the low side and you might need to adjust it a small amount like you did. If you have pH UP (any brand) you can use that.
