Was a good week this week plant wise! Finally got the discoloration resolved, still feeding Cal-Mag and it seems to have done the trick. Will keep up to it and probably add to most grows going forward once flower hits. Also have been continuing to check the reservoir daily to keep PH at 5.9-6.2. Not taking a lot, but am having to add 1-3 ml of PH Down daily. The two girls on the right (no airdome) have grown noticeably this week, still 4" shorter than the biggest girl with some, but larger than the smaller one. #4 (front right) had even darkened back to a more "normal" colour. #3 (back right) seems to enjoy being a brighter more lime shade of green for now, but she looks happy otherwise, and even droops closer to lights out than #4. There was ONE hiccup this week, but luckily I caught it quickly so no real damage, but it was close! What happened? I had been noticing that the nutrients were not staying mixed even though new bottles, so I thought I would try without the UC Roots, thinking it was causing seperation. Turned out it was, but not of the nutrients, instead of my hard water 🤦‍♂️. Don't know why it didn't even cross my mind, but opened the tent Saturday morning (thankfully) and thought "hmm the leaves look dry on this one better check the valves.". Turns out, all 4 plants were dry!!!! I ran to workroom, grabbed the 4 spare autopot trays, put plants in new trays with water from res that I put in with a cup, then turned to figure out WTF happened. Turns out had a serious blockage between the reservoir and the valve just inside the tent. So changed out all the trays, valves, and reservoir as well as flushed the lines before refilling and turning system back on. So so so glad I caught it in the morning, if it had been evening I think I would have had some seriously damaged plants! So lesson learned, with hard water make sure to use a line cleaner, and to clean the valves every 2-3 weeks. Flush lines weekly going forward.
