Iron deficiency? Overwatering? pH imbalance? Nute burn? None of the above? (pics)

Hello everyone. I am an novice/intermediate grower with an advanced degree on Botany.

This picture is of a Blueberry female who I believe was having an overwatering problem. But then I noticed there was some interveinal chlorosis at the top of the plant. I then started thinking it was an Fe deficiency. Then I looked at my other plants and all of them have the deep veins. This includes all the plants in oasis cubes and soil. I then ran some of the basic tests and I'll tell you what I found and decided to do. Let me know what you think. I hope I picked the right solution.

looks kinda weird but no problems that you can really fix. how fast is it growing?

I think it stopped growing.

This is how my plant is too. Any solution?

Don't water it so much, let the first couple of inches of medium dry between watering and put it in a bigger pot, looks very fat for such a small plants it's probably getting root bound.

Hey guys. Overwatering was only specific to this plant, which I caught just before this main problem occurred. This Blueberry was hit back to back with stresses. It went from nute burn to over watering to what I think this is today; nute lockout due to a low pH. I started seeing multiple deficiencies and so I decided to check the pH. It was 4.9!!! I have not seen the pH of DI (with CalMag) drift so much in 2-3 days. It was 6.0 just a few days ago. today there were Mg, N, P, K deficiencies on some of the other plants. Seeing these multi-symptoms further confirmed my hypothesis that it was the pH causing the nutes to lockout. I flushed with pH corrected H2O last night, drained them well, and I hope they are now under control. Do you think this is a correct diagnosis and solution because I have never had nute lockout?

I currently have them on DI (w/CalMag). When should I revert back to using nutes? 2 days? 1 week? Help is appreciated.

Thanks!

Hey Man--

Yeah I think you did the right thing. Now just leave it alone and feed lightly. I had over-watered and over-fert. the soil w/ peat moss, making it way to acidic. The plant had completely stopped growing-- so I had to transplant it, and it took less then 4 days for me to see positive results. You should notice in the next 48 hours if you made the right call. If the plant doesn't get any worse-- its a very good sign.

Jus' keep an eye on the Ph from now on and your plants will thrive.

Good luck with your grow

--- BTW revert back to nutes once your plant completely recovers. I would wait atleast a week or two before even considering it. Just use your judgement-- when you do begin to introduce nutes again, do it slowly. And perhaps for the time being, trying to spray the leaves on the plant and have them absorb the moisture -- giving the roots a bit of break (With filtered/Plain water only) .... thats what I did anyways, and it worked for me-- good luck with yours!

This means my stupidity and lack of growing experience gets me in trouble. Then when I start thinking a little bit, I pull myself out of it.

The plants are recovering very nicely. But now I'm in a catch-22. The plants need nutes but the smaller ones cannot take more than just DI. I have the larger ones on 1/4 strength and they are starting to grow and obviously recovered much faster. But the smaller ones need nutes because of their deficiency, but they cannot take it. So what do you do? I agree that foliar feeding should be supplemented more oftern. They are going to need nutes at some point and knowing when the earliest/best possible time is going to be a challenge. I see patience.

You could see the plants struggling on all levels of the energy conversion process. That's probably the best way to describe a nute lockout experience. A complete shutdown of the system. While it sucked to go through it, it was caught early and so the growing experience was worth it.

So here's the root question of this experience: How often do you check your pH?
