HELP!!! Yellowing Issues I can not Figure Out

I have a few plants that I was going to send into flower a while back so I switched to 12/12 for a week. I brought them back out of flower to full 24hr. I have major yellowing going on with a lot of leaf lost.

Now I have other plants that are yellowing also and they are all over a few months old.

I have been using Cal Mag but it is Botanic-care. I have been feeding GH 3 parts with Hydrozyme Growth Excel, Mother tea, Cal Mag, N PH down I know I am missing some stuff on this list.

Since bringing them out of flower I have not seen any new growth and it has been almost two weeks. I have been flushing.

PH tap now is 7.1

PH T.D.S is only 30 so the water would be soft? Wright? I can get PICS if necessary...

BUT any advice would be greatly appreciated.

Since I have a garden going I was going to take the Donors and flower them and make new Mom's

Do you think it can be IRON?

I've been hitting them with all supps other then....

Or could it be not enough of bloom being that they came out of bloom messing them up?

Any help would be appreciated...

I have just been going in a 5 gallon set up 20Ml micro 20Ml grow and 20Ml bloom on everything because the clones are fresh.....

Tomorrow I get the T.D.S pen Back called Oakton they straightened it out in 1 day Hydro Farm was saying 3 weeks plus... Feed the Dog that Barks I guess... LOL:D

As for the pH, are you adjusting your fert water BEFORE or AFTER mixing your nutes?
A tap water with ppm=30 and pH=7.1 you might not even be getting a very accurate pH reading because your ionic strength is low at only 30ppm. It's both easier, and more accurate, to do all the pH-ing after mixing your nutes.

I have been testing PH before and after adding NUTES. I've done everything I was taught and KNOW and I'm having issues. I think it has to be some crazy deficiency... They are sucking up anything that get thrown @ them. I will most definitely have PICS in the A.M I really appreciate the HELP!!!!!
