do my Dark devils need more food?

Muddy and Blue very much appreciated..

I also bought a cheap fish pump and air stone to bubble my water for ever how long to add oxygen after i add nutes . to many growers swear buy this and It totally makes perfect since.

Muddy to lower my feed water ph would vinegar work just fine?
 
Vinegar or lemon juice will work.
 
i mixed 1 gallon tap water with 1.5 tspoon white vinegar dropped it to 5.8 ..

I gave each plant about 4 cups of this low ph water and the run off is around 6.6 now. the lowest its ever been. This lime green leave issue is strange to me because I have two dark phenos and they both show this in the leaves. the leaves are all the same from top to bottom even the newest leaves are the same green. no tissue damage no spots no clawing just lime green.

I guess ill just monitor them closely.. and no more water for a few days. i do use a water meter that tells me when the soils are dry and they really suck the soil dry very quick!
 
Here are more pics this is 8 hours or more after the ph drop. I know there is nutes in my soil.
Im on 3/4 strength and there young for that high of nutes but maybe im wrong.

Thanks everybody..
 
Elvis,

The best thing I have done in my learning curve is to get one line of nutes, and follow the program. I used to do like you : adding this or that to take of an immediate problem. I was going from one problem to another. Since I have been following the regimen of the nute maker, I have had no problems with great results. It makes life easier man for sure.
 
If the high pH was starting to lock out the iron, it's going to take a little while for them to recover. In the mean time I wouldn't feed above half strength. Excess nutes can cause their own set of issues. How are your temps running, light on and lights off?

Muddy its runs warm inside the average is 27 30 cel with lamps on and 25 to 19 cel with lamps off. I feel like your on target with iron issue. i have other Dark devils total of 4, but only the two purple phenos have this issue. the other dark devils are very very green along with
the delicious cheese candy and the Buddhas are all fine and live in the same soil and get the same nutes...
