Today is day 24 from seed germination, but I'll call it an even week 3. I am feeding her 575ppm nutes holding a steady pH of 5.9. She is greening up a lot from her underfeeding experience, but altogether she is doing quite well. At her next res change I'll be upping the Pro-TeKt and adding some Mag-Pro and Dyna-Zyme as per the feeding schedule. Considering adding a bit of some Mammoth P I have lying around, though I might just save that for flowering.
10/26 Update: Added another picture of her growth and roots to document her progress. Roots are growing quite rapidly and she is drinking her nutes steadily, but not seeing a huge dip or swing in her ppm readings. Next res change will be later today. Current ppm of new nutes is 740 (TAP + 570ppm) Not sure how far down I will water it. It definitely has a bit more Foliage-Pro, but most of the additional PPMs come from the added Dyna-Zyme and Mag-Pro. I don't expect a burn since it's only 570ppm of nutes, 1.14ec, and Dyna-Gro suggests around 845 PLUS the Tap value. I might dial it back to 1ec + Tap (670ppm total, Tap is 170ppm) since the current reading is approximately .8ec + Tap.
I also dropped the lights to around 16" since, according to Mars Hydro, the PAR values for that distance should be right around 400-450. I do have a second Mars Hydro SP150 that will also be added once these start bushing out. The added light should allow me to evenly cover the 3'x3' ScrOG perfectly at 12-16" during flower. I received these lights during the last two weeks of my last run and this will be the first time seeing how they run compared to my old light (Viparspectra 600w). The new lights pull almost to the watt the same as my old light, but put out about 4x more PAR with much better distribution than the old Viparspectra, in addition to being full-spectrum QB led panels, AND running 10+ degrees cooler (Fahrenheit), WITH legit Meanwell drivers.
