I have been watching the pH very closely since rez clean/change yesterday. This is so bizarre to me because yes I am used to a slow a steady RISE in pH not a quick drop. So I did not add the cal-mag or silica blast this time to see if that contributed to the problem. It looks like it is happening again without the 2 supplements. Ph went from 5.9 to 5.2 in about 8 hours and seems like it is getting cloudy. Thankfully I stay on top of it and the seedlings look very healthy. Another thing that I am doing differently this grow and didnt mention is active cooling. There is quite a bit of cool air blowing onto the system but I don't think that should do anything. Ambient temp is 81 deg. F.

I have a fresh bottle of pH UP that I will use. Possibly the pH up is unstable or something. It is a GH product. Maybe the addition of the new Floraliscous Plus when it arrives will help out too who knows. THat's the only thing missing right now in in my recomended feeding chart recipe that I use.
