Growing some spring delights

Well I'm not having much success with Phoenix seeds. I've decided to start detailing seeds that fail to germinate, maybe I'll get sent some new seeds :) ?. Knowing my luck the two ungerminated seeds will burst into life next week and then I end up with a cramped grow room which I was desperately trying not to happen, but I guess I got too enthusiastic and greedy again lol. This time, well as per usual, have been messing with my soil mix. I wanted to try and make the soil around 6.5ph, so have add stuff like potash, iron sulphate, fish and bone meal, worm castings, bat mix, lava rock, and some seaweed for good measure. Oh yeah, put about 70mg of mycelium stuff :). Anyways, the ph level went back to 7. So gave up on that as was concerned I may be putting too many minerals in. Geez, I really should just leave it. The base potting mix is Plagron Batmix. I probably don't need to mess with it, but can't help myself.
