Plant is still looking fine.
I took a pic of my little one and when I zoomed in it had loads of white dots on the leaves which I can only guess will be trich sites. I think ElephantRider noticed the same with his. Your plant has the same dots if you look closely. As it happens, Elephant Rider has a CH9 seed as do I and I've never seen that trait before, so maybe we can identify your bagseed as a CH9 offspring.
Then again I may be talking rubbish
Try to use the 6.5 water rather than the 7.5 as weed prefers it slightly acidic, but neither should cause any big problem. Just remember that tap water can change so it needs checking regularly and also when adding nutes you should check the value after everything has been added. Many nutes affect ph noticeably.
