Someone please help.. discoloration

What would be causing my plants to start yellowing from the bottom up? I know when a plant is growing too fast some of the new growth could be kinda limey-green looking, but these are the bottom leaves. The new growth is all green and lush now. Could the plants have took the chlorophyll from the bigger leaves to support the new growth?

All the yellowed leaves seem to have some dark green blochiness to them too that wasn't there before. It's almost like the color is bleeding back in to them.

It seems to be getting worse and I'm gettin' a'scared! :jointsmile:

I don't have time atm to do the TS Form. I have to go for now, but I figured I would go ahead an make the post. Thanks for any help.

Could someone post a couple of pics or lead me to some info on PH problems in young plants? I think that is my problem and I wont have a tester for a week at least. Thanks for anything you guys got.

Similar to the yellowing I saw when my pH was off. But either way, the droop of the leaves shows too much watering. So go sparingly until you get the tester. Let the top inch or two of soil dry out before watering again.

OK thanks for the reply; I just went and got a PH test kit and my tap water going in reads 7.4 which I believe is high. I am not that knowledgable when it comes to pH. I mixed up a sample of nutes at full str just out of curiousity and it reads between 6.8-7.0. I got some pH up & down as well. I was hoping someone could tell me the best way to go from here?

Thanks for any help.

Correction:
Tap Water reads 7.6
I poured out a gallon and started adding pH down. It drops 0.2 for every 2 drops I put in.

So if I'm starting with 7.6 plain water and 7.0 with full strength nutes.
How much pH down should I add to my tap water? 8 drops/gal to bring it to 6.8? more?
What about nuted water?

I guess I'm asking what the ideal soil grow pH in and out should be.

I put my cam on 5 megapixel or w/e so you can zoom in on the plants really well. I have narrowed it down to 2 things it could possibly be... pH problems or just root shock from transplanting.

couple updates, i think its getting worse.

Just found a rusty colored spot =(

Alright... They look PH stressed. Have you given them nutes?

For soil you should aim for 6.5-6.8 PH.

Also the nutes... You said full str? Try going half str for a week and see how they react.

Always start at about 1/4 str nute solution and see how they react. If good you can increase the nutes over time. By doing that you will find the right amount of nutes that the plant can handle at any given time. If they react bad then back down a little bit.

ALWAYS PH your nute/water solution after it is mixed. PH adjustment should be the last thing done to the mix/water before it goes to the plant.

Did you get a ph pen or drops?

It's N deff, but if your ph is 7 it's fine in soil, 6.8 is perfect
