Real Gorill4, DoSiDo's & Purkle #1

I started the week out with a full flush of all plants. I believe there were some pH issues that were locking out nutes. I ran the first flush with 6.0 water only to notice my runoff on each was sitting around 5.8. I did another flush with 6.5 and got the runoff on each to be between 6.0 and 6.5. So it seems my soil mixture may have thrown things off a little too low on the pH spectrum. I fully expected to see droopy plants today after such a big flush but they are actually looking better today than before. I will include and image of the droopiness before the flush and the improvement of the plants after. I have decided not to top until 2 weeks after transplant. Update 1/21/19: Plants look as if they may have corrected their issues. I feel like I see a growth spurt in a few. New growth shows no signs of deficiency and the problem areas seem to all be on old growth so that is a positive. It will be at least a couple days before they get another water due to the flush. I cant really determine if the light height has been raised at all because I had them sitting on wire racks to dry out and had to raise the light quite a bit for that. The bottoms have dried out pretty well so they are back on the floor and between 1.5 to 2 inches from the plants. Update 1/23/19: Plants watered with 1.5 gallons of water pH'd to 6.2. Runoff was between 6.2 and 6.5. Purkle #1 looks like it needs to begin some training as it is growing off centered. I will rotate the pot slightly to see if it will self adjust and if not, I will start using my training ring on it. Lights were raised to about 2 inches from plant. I would like them to grow a bit more vertically so that the leaves will be more above the pot level and at a better position for the training ring. Update 1/25/19: Last update of week 4! I have some sort of deficiency starting to show on Purkle #1 and possibly also on the DoSiDo. It is presenting as very light green areas in between the veins and is even on new growth. I am leaning towards nitrogen but I am just not experienced enough to diagnose on my own so I need to do some research. For now I will not take any action and will just keep a close eye on it since it is presenting right after a very hard flush. I am beginning to rethink a 60 day veg. I measured each plant today (I will include measurements below) and I have to think that I may get triple that height during stretch. Just something to consider as I go but I will be keeping a much closer eye on the measurements. Purkle #1 also got a small amount of training to help with its tendency to lean to one side. The plants were not quite tall enough for the training rings so I used a bamboo stick to tether the plant to. I have been trying to maintain about 2" distance for the light.
