My soil PH is dead on 7 should I reduce?

No @M0use that is only true if you have a living soil. When you use a normal soil without organismes and the right bacteria living in their it doesn't regulate shit because it is not living... I always make living soil with bacteria and fungi that regulate and work together with the plants root system. But you need to feed them from the start till the roots can provide then with enough sugar to be self regulating. But when you are feeding them bottled nutrients and nothing for the soil life there is really nothing living in there! Goodluck PaxIlluminare! 😋

7 is fine, I would not worry about it, your plant will grow perfectly at this reading.

Yes, you should lower the pH of your water. Bad things start to happen when your plant is in neutral soil. Powdery mildew is easier for your plants to catch. Molds thrive in this pH. Pests will start chewing on your plants because they aren't as healthy as they should be. A lot of people don't realize how important pH and pH testing is. Try and keep your pH moving between 6.0-6.8. Doing that helps your plants take in all the varying minerals and nutrients it needs to thrive. pH also influences the rhizosphere. The rhizosphere is a bunch of microbes that help break down different things to make soluble for your plant's roots. All these things are what help make a plant healthy and close to untouchable for pests and mildews/molds. So, don't forget to feed your rhizosphere! 1-3 tablespoons of unsulfured molasses per gallon, once a week. I hope this helps.

I'm with m0use on this one!

Your seedlings look rather normal I would not do anything drastic to try and fix a problem that's hardly noticeable, just water with a 6.5 ph for the next few and your soil ph should lower if not when you get to your 2nd or 3rd node a light feeding of recharge will keep them going no sweat.

High PaIlluminare, You can buy and use P minus, I know that BioBizz has a biological version. But there are quite a few natural ways in which you can reduce the pH of garden soil over time. Using organic materials like well-decomposed compost, compost tea, elemental garden sulfur, mulch, coffee grounds, and sphagnum peat moss in your garden can help lower the pH of the soil naturally. Happy Growing! 😋
