ILGM GG AF First Grow!

The entire grow has been littered with mistakes and i unfortunately did not record/ check information such as nutrient levels, EC, or humidity as accurately as i could have. so I'm just gonna list them off as i go and eyeball the numbers with the information i have. 1.snapped the main stem of the top right plant and propped it back up, a fair bit of plant is still attached, and only the first node above the snapped side died. 2. Snapped a node off from the center plant, i could of saved it if i taped it up in time, but i didn't, and it grew limply for awhile until i plucked it off noticeably improvement in growth on the other side. humidity stayed a steady 55-60 percent with the extra watering, still 30- 40 during night. Changed the lighting to 20-4 then 18-6 after noticing alot of growth over night. I'm sure the switch to 20-4 helped. as for the switch from 20-4 to 18-16 i think it helped, may be coincidental. At some point i did a basic ph test with a color solution and noticed it was a tad bit high, but didn't put any thought to it.
