Good Job Fat, From what I can see and from what you've done, This would be my educated guess as to whats up. During the time before the plants were able to be flushed, some of the nutrients became Locked out only because the concentration of nutrients was too high, and by the time you flushed them some of the Nutrients became available, but not all of them, which means u need to go through the flush process just once more and we'll make some correction, in that process. When I flush I usually weigh the pots when they are dry. In your case the 5inch dry pots average about 4.30 ounces when soil is dry, so what I do then is I'd pour 8 ounces of RO water, (if you can,go buy 4 jugs of Purified Reverse Osmosis water, your doing so, because most brands ph their water to pH 7(this will be 1 less thing you'll need to worry about pH'ing). More importantly if you havent purchases a ph meter there is a cheaper alternative but not the best; go to a home and gardening and asking for a Ph test kit for pools. it'll cost no more than 25 bucks, we'll need to know the ph reading of the runoff once you've poured that 8 ounces RO water into the plant pot(I suspect your Soils pH is very low, around the 5.1-5.3 range when it should be No Lower than about 5.9pH, you'll read or hear about how ppl have grew in Soil with low ph and still got the plant to harvest with no problems But imagine if they'd Dialed'in to the plants Targeted ranges they'd prolly get a higher Yield. Anyhowzers While you're at the home and gardening store also Ask for "Lime" for soil, 'Sunniland' makes Lime that is grinded up to a consistency similiar to sand which is what we want, u dont want pellets. Anyhowzers Buy the Lime which will come in a big bag for very cheap, I'll explain what to do with it later.If you had a ppm meter we could accurately measure EC which is relative to the amount of nutrients is in the soil. In your case I'll try and help you with a 2ndary method that doesnt involve a meter, This method is very simple you'll judge by the color of your run off, If your runoff looks that brown color of Tea, then the EC is still too high!, so AFTER you've poured the first 8 ounces of water which we used to give us some bearings, You'll now TAKE Some actions, start by pouring 2wice the wet-weight of the POT and since wet-weight is roughly 10-12oz, then that means you'll pour about 20-22 ounces of water, down the plant again. After you finished with that good your done with phase one, now, Phase 2, you'll grab another 1 gallon of RO water you bought earlier, and in this one you'll Pour a tsp of Lime in the jug shake it up, Then we'll pour 20 ounces of that into your 5inch pots which will bring your soil's ph up where it needs to be(roughly a 5.9 - 6.1). Now with that out the way you're done! YOU dont have to worry about feeding the plants nutrients because there are still a lot of it in your soil!! Give it a full DAY before you start making anymore changes. We let mother nature take over from here. I should mention that after finding out how to raise ph with Lime I suspect that if the Soil's ph is in the 5.9 - 7.0 ph range(and keep in mind that your Soil's ph is not the same as your Nutrients PH), I'm talking about the PH of soil, but to continue with what I was saying If your soil's pH is in that target range your plants MIGHT be able to uptake Nutrients EVEN at a higher EC. This hasnt been fully test yet. But what I did was I took two plants, repotted them in some New FFOF soil after a few days I ph'd the soil then I flushed one to .8EC and the other was Flushed to a 1.8 EC here it is 2 days later they BOTH have their leaves pointing up and are happy

.(So this leads me to believe with the right soil ph it gives you some flexibility with the plants uptake) Which I can go into more detail but as of right now things are just speculation. Let me add: Dont just blindly do what I told you to do...YOU should know What your doing and WHY you are doing it. Quick Notes for that very last pictuer you posted: I will just randomly pick plants and speak on them as the leaves grab my attention 1. THere is a plant that is Top Rightmost and its mostly out of picture EXCEPT for its clawing leaves, that plant has received to much nutrients or hasnt been flushed enough, flush her(Look at the clawing in the leaf tips) 2.To the Left of the plant is another plant, which looks like its ok for the most part 3. Then you have a plant to the Left of that plant at the top which has drooping leaves but most importantly it looks like it suffer so much nutrient lockout that it Appears to be having a Mg/zinc deficiency, but look up Magnesium deficiency and also lookup Zinc Def. to familiarize yourself with it.....But even if it is one of those deficiencies, You wont have to do much to the plants because we've just unlocked them from Nut lockout by flushing them, so these plants should show some improvement after a week as long as you've what was stated in this post.
