The folks recommending to not pH water are correct to a point. I grow in Fox Farms and stay all organic through the grow. This will change if you use a pour liquid that mixes with water. If you use organic sprinkle like Dr Earth or gia green pH not needed.
That pot has nutes for about 4 weeks. By week 3 you will need to top dress your pots. The great thing is you can use your soil for top dressing. After 3 weeks put a couple inches of your OF mix on top with perhaps some earth worm castings added.
Flower will need different nutes, more p and k. To keep your organic grow in flower. Again gia green or Dr Earth flower girls are good choices.
Now when I look at you app I see your VDP is high for a seedling. This will cause your plants to over transpire and at this early stage we need to fix that. Get some more humidity in the tent to lower your vdp to seedling amounts of close to .7 vdp I see your duct pull is on setting 3. Lots of air moving is needed to keep mold and mildew down but this is not an issue in seedling stage. This is both pulling out your heat generated by the light and any humidity. Shoot for 78 degrees and about 78% RH as this would give you around .7 vdp . If you can not maintain at least 75 daytime temps you will have a slow grow You can get plenty of air exchange with a 1 minute on and say 30 minutes off. If you need help setting up the app I can help with that as I use both
Vivosun and ACI controllers in my grow
Let's get this to veg stage and any help you need just ask
