Didn't feed enough to get any runoff this time. I'm pretty sure they are ok for now, next time I'll start with water test the runoff and feed.
Had to move the lights up a bit and I'm losing leaves. That is my fault for not being proactive. But it could be the strain. Fed them a bit stronger this time I put EC was 1.2 and pH was 6.3. this all started out per 1gal but the EC was 1.4 so I cut it with another 1l2 gallon. That final EC is what matters anyway.
I will discontinue the grow big after this week. Tiger bloom should have enough. We only have about 3 weeks left. So the next feeding will be the last big one, then I'll lower it, then just water. I'll feed up to the last week so they can really fatten up on those last 2 weeks. I'll let them sit in the dark for 2 days before I chop. In the same tent I'll dry them in. So that means I'll need add a scrubber to that tent so they don't stink up the neighborhood. Good thing I think about that already. I have a little 2x3x3 tent I can dry them in.

I didn't have time to do a water push and feed so I just gave each 2cups of plain water to get em through till the next day.

I pushed about 2700ml through each slowly to generate runoff. Vermiculite is not your friend with this type growing, but I have finally totally reworked the soil into an inert substrate that only holds the roots. All organic material and most likely any trave of the herd is all but gone. Again, you need to go back to the beginning to learn how I fucked all that up and made a switch from living to basic hydro in the first few weeks. It had to be done due to the use of unprocessed soil. I knew better but thought the soil was older. Anyhow... I had suspected my ex was high because I've not been able to produce runoff. In this soil mix it only starts once you approach the 3 liter mark so after 2 light feedings and due to high EC before I wanted to push some water through for peace of mind and then feed.
Results:
BBA EC: 1.6, pH: 6.6
BCA EC: 1.2 pH: 6.6
The BBa was always a bit higher but these #'s are exactly what I wanted. I didn't feed yet. I'm going to let them dry for 2 days and then I'll feed. I believe that when the substrate is soaked it dilutes the nutrient solution and I want to stop any chance of channeling. I'll give each about 1200 to 1800ml of solution @ EC 1.2 -1.4 probably the last good feeding. It's light still but I'm still treading lightly with the autos.

Still too wet to feed, they should be good tomorrow.
