I've been busy tweaking a few things in my setup and haven't had time to update. I took the pictures, but that's as far as I got. I was having some pretty serious heat issues; they would get up into the low 90s. I corrected that by attaching ducting to my exhaust and directing it out the window. On the other side I installed a window fan to bring cool air into the room (not the grow room) and opened the mesh screen on that side. I also have my lights turn off between 2-8pm. I will probably still need an A/C come flower time during the hotter part of the summer, but for now temps seem to be within range.
Another problem I had, which was rather frustrating, is my handyman knocked over my ballast and broke it, so I had to order a new one. For a few 4-5 days my plants were running off of one 1000w light, which I'm gudoenessing is why some plants are further along then others. I actually bought a whole new lighting setup because it was $40 more and I may need to replace something else down the line.
My PPM stayed around 420 so I didn't change it, until one day I found it at and decided it was time to do a res change and increase the nutrients, I was less prepared for this as well. I got it 850 PPM and a pH f 5.9. I actually added too much pH down and it was reading at 5.2, so I added some tap water to bring it back up since I read mixing pH up and down was a bad idea. I was aiming for a ppm around 700, but I ran out of time because my lights went out and my green light is still on the way. I'll check on it tomorrow to see how the plants are responding.
As you can see, some of them are starting to grow through the screens already, and they were topped at multiple sites not too many days ago. If there is anything you guys think I should be doing differently please let me know.
