Thx for the feedback. I don't think it is over water. I am sure I water them when soil is dry enough.
Any feedbacks are still welcome!

I think you have too much P-K and its affecting uptake of N and other micro nutrients such as iron, calcium and mg. Did you ph your water when watering? If the ph was too high then over time build up of P- K and because u have a build up of P-K it looks like a deficiency because it cannot uptake it. This happen to mon, fine while in veg but then when flip to flower, plants need more P-K but since ph was too high plants didn't get P-K it just build up.

More like phosphorus lock out, adding more wont help if it's not taking it in, in fact it will hurt.

I have three plants in the tent. two of them in 3 gal smart pot, one in 6 gal pot.
I just did Slurry test. not sure if I messure it right. I can not get 2 oz soil from the pot, because roots all over, I can feel I break the roots when I dig it. PH 6.2 after I mix Ph7.0 water with soil. If I am having problem with PH, I guess I am having my PH too low is that correct?
If I am having PH problem I think I have it too low. After I did the Slurry test, I got my Ph at 6.2.
I tried too put more N and more P K when feed. nothing helps at all.
I feed them around PH 6.0
What would you do to fix this?
Appreciate all you guys feedback!

In soil a ph of 6.0 going in your plant cannot uptake P. Water them with a ph of 6.5 if you are in soil. If you have been watering with a 6.0 ph then most P of N-P-K is still in the soil and has not been used by the plant.
If you are in coco 6.0 would be ok but 5.8 would be better.

Raise the ph when you water and stop giving such high P-K the plant has abundant P and will use it if you raise the ph, that is if u are in soil. If you keep throwing P at it because it looks P deficiency, you are burning the roots. It needs "P" the "P" is there but it can't uptake it because the ph is too low. JMHO

Thanks for the reply again[
QUOTE="Bbcchance, post: 12557358, member: 907590"]in soil? dolomite lime[/QUOTE]
never use it before. How do I use it? How does it actually work?
I fed them about two days ago, seems I should have my PH higher, and its not getting well at all. Do I have to wait till it dry to feed them again? They also drink slower than they used to
I usually have water in between feed, but My plants are not heathy. Do I have to feed them every time till recover or I can still go feed- water-feed?
Actually I have another plant in soil with 5 gal pot showing symptom of Def. too
They were fed the same until one week after I moved them into flower tent.
I wonder this might be the same issue?
This is the one still in veg

I assumed my PH is lower then what it needs to be. How about I feed them with PH 7.0 make sure they back in range and go PH 6.5 like you suggest?

Hi again,
in my opinion, the last picture they dont look so bad, i think better than the first pictures. It looks like a breeze of Mag, Cal, N def again to me with a little P def. Maybe the others have right a PH Problem. 6-6.2 ist also for me to low especially in a long time you used this. PH should vary somewhat. I use from now a ph of 6.3 to 6.5 and sometimes i let the PH about 6.7 to 6.8 after nutrients and without a PH-.
I found this
http://www.nutrientstewardship.com/implement-4rs/article/soil-ph-and-availability-plant-nutrients
also the picture
At least, dont forget the plants need a time to react and also time to see a change. But i understand you, cause you have some problems in the Bloom Stage which is very important for us smoking people or whatever and when you have 3-4 weeks problems in the bloom you loose this 3-4 weeks for creating buds (yield).
But cheer up! and patience you learn, just like me and you will be better.
I forgot something, a gardener says to me, if you have, for example, only 2 leaves showing deficiency, or simply show anything, it does not mean that the whole plant has problems or becomes completely broken. Sometimes that means nothing but that does not refer now to your problem. sorry my english isnt the best.

Good day guys,
@lio lacidem @Bbcchance
I just bought some lime today. I guy in store told me this should be mix with soil before plant get in. I am not sure if I can put some on the surface of soil, and water with PH 6.5 water. Does that work? and How much lime I actually need it?
As @420mon mentioned I should still have P that having been use by plants in soil.
Should I just water with straight PH water. Do I need to add some nutes in it?
I feed them three days ago, they should be dry in 4 days. now it takes about a week to dry.
In bloom stage I want to correct it problem as fast as possible, but soil isnt dry yet.
Do I wait till it dry? Worry about over water.
@budilicius
Last pic is the one still in veg stage.
I thought about cal-mag def. before. They have been adding Cal-mag since two weeks ago. Still not seeing any recover( Lots of lower leaves turn yellow everyday)

--- in my experienced, when I see 2 leaves showing def. most of time I have it fucked up the whole plant.
Thank god I have RIU here. or I might never figure it out what I missed.
Once again appreciated all you guys reply.
happy grow

i have this exact issue in veg all good. After a week in flower this happens. I water everyday and add cal mag. But it's still happening. Should I use phosphorus as well? I'm in a closed room with 9k. They eat a lot and fast
