Everything is looking fantastic finishing up week 4 veg. All plants are beautifully lush, including the fully organic plant (A) which was a little finicky in the beginning. The DWC plant (D) is very obviously the largest plant and has been topped and LST'd multiple times in an attempt to flatten it out...I actually broke a main stem on it while putting an LST clip in and am now rooting it for a non-planned clone...it was just too big and pretty of a branch to throw in the trash. Hoping it will root soon enough to be able to be flowered. These plants want to grow lanky, so bushing them out has been some work but no real problem. The scrog net went in a few days ago and the two 5gal plants (A & B) are already about where they need to be size-wise considering leaving room for stretch going into flower...but, the 3gal plant (C) still has a little more net to fill before she is ready...I'd say no more than another week and a half. Soil pH test (digital meter) for the plants were all within an acceptable range this week from 5.6-6.2. Runoff has been pretty consistent as well with the runoff ppm beginning to level out with the input solution for the plants getting synthetic nutrients. The organic plant is coming out around 6.7 which is a little higher than I prefer so the water will be lowered to 6.1 for the next few waterings. Switched to Sensi Grow from MGB this past week and so far, so good...pretty sure it's the same product with a different NPK ratio, but the ratio looks better for veg to me. Should be flipping to flower within the next two weeks max, most likely sooner. If I wait much longer, I will have bigger plants than I can handle with a 4x4 tent. VPD still around 1.2-1.5 and DLI around 18 with PPFD at 350 in the center and 250 in the corners. Clones will be taken next week to be used to create feminized seeds and collect pollen. I realize feminized plants aren't normally used for breeding outside of reversing, but I like to store pollen for future projects anyway.
Update: DWC plant (D) has now exhibited abnormal growth, splitting off into two new heads from one node, essentially topping itself. D has now been eliminated from the breeding run, leaving A, B, and C. D will still still be grown out for it's flower, but will not be bred.
