Temporary Tent Grow Attempt.

-Mk. Ultra had Powdery mildew signs again... -Found the culprit that is responsible for the unrelenting powdery mildew! Unknown #3 has been hiding small remnants of it on the lower foliage. -Unknown #3 has been distanced from the rest of the plants and was given an application of my Fungicide as treatment. -The whole grow room was sprayed with a thin layer of the fungicide and another layer will be applied tomorrow before the light cycle. -Unknown #1 is growing beautifully with big dense tops! -Unknown #2 is also growing very nicely but with less dense formation, lamp on that side of the room has been lowered by 10cm to compensate. -Mk. Ultra has been treated for the powdery mildew and all severely affected foliage has been carefully removed. -Unknown # still showing the Calcium deficiency, though with slower spread due to the increased "micro" dosage but not enough to stop it completely and resume proper normal growth. A Calcium additive will be added as soon as it arrives since I don't want to overuse the "micro" fertilizer due to it's high Nitrogen content compared to other micro/trace nutrients. -Overall everything is coming along nicely besides Unknown #3 that was problematic from the first week. I already put too much effort into her to give up so I will keep her separated with manual irrigation until she is ready to be harvested or at least when she resumes her healthy growth.
