First grow ever! White Widow Auto

Day 1-This is my first grow ever and I'm really looking forward to it. After what seemed like forever my seeds finally came in and I've selected the 3 White Widow Auto seeds that came free with my order. I'm just gonna put 'em in a paper towel to germinate and go from there. It might be a little overkill but I selected 7 gallon fabric pots to grow in and I'll be planting the germinated seeds directly into their final home. Seeing as how I'm new to this I went with some mainstream products: Happy Frog Potting Soil with Advanced Nutrients Bloom, Micro, and Grow. I'm using the 100w Alphapar LED light that came with my setup. Day 4- 72 hours later and only one seed has started so far. Hopefully the others follow suit quickly but if they don't I'm not too worried about it seeing as they were free with the order. I'll drop this one in the dirt, add some water and see how it goes. Day 6- The other seeds didn't pop so I decided to go with plan B and get one GG#4 and GSC started as well but I made a mistake that hopefully I can rectify before it does any harm. I ph balanced 4 liters of water in a large measuring pitcher to 6.5 before I started but somehow today the ph of that water was above 8. No wonder my seeds didn't want to start growing! I guess I need to let the water sit for a minute and check it again before I assume the ph is correct, or maybe my ph meter is just a cheap piece of junk or both. I probably overwatered today with non ph treated water to try to push some of that bad water out or at least dilute it so we'll see what happens. Day 7- My baby girl popped her head up out of the dirt on day 6! Lookin forward to seein her grow but a little disappointed that I only got 1 out of 3 but I won't make the same mistakes with the ph of the water next time.
