Here are the pictures and they look a little better this morning, and I am not seeing the browning on any new leaves. Just on the new growth I have not seen it so light green before.
In the third pic it shows the growth spurt, almost 15" is this normal?
Or do you think it is stretching for light? I am adding two more lights on Monday.

Ah pictures! She's definitely looking better, though the new growth is PRETTY light colored. It kind of looks like a sulfur deficiency, but I'd lean more towards a pH imbalance. What were the results of your soil test?
Also that's a big stretch for only being in 12/12 for one day. They probably are stretching for the light, as your internode spacing looks pretty long. What LED are you using, and what additional lights did you add? It should be alright, but if you fix these little problems now, you'll be rewarded later!

Here's a list of deficiencies with real pictures instead of drawings:
Which deficiency do you have? Real Pictures
I'm leaning toward sulfur as well.

I am unable to do the soil test as my plants are clipped right down to the top of the pot ( lesson learned)
But I did do a PH test on the leached water after 20 mins and they were all 6.6 and 6.7, but wish I could really do the slury test.
I might try tomorrow on one to see if I can get any soil but it doesn't look good, I have the plant pretty twisted around the top.
Picture at bottom of post.
The stretch occurred over 5 days approximately but it's the most I have seen them grow ever.
It all started after I watered with the cal/mag and molasses but only on 3 of the 4 plants, same with the lighter growth.
The Leds I bought are cheap but I am on a tight budget and started with 2, I will have 2 more on Monday.
I have plans on upgrading later on and using these this winter to grow Tomatoes and Peppers.

Hmm, interesting. I'm using the same light as you, and mine is covering a 2'x2' SCROG with no problems (journal link is in signature if interested). What is your height above the plants? I've had good luck with 18-20" in veg, and 12" in flowering, as recommended by the manufacturer. TopLED and Mars Hydro are the same too, in case you didn't know.
Looks like the LST should help with your height issue, and the color in the last picture looks pretty good to me. Was the other picture of other plants?

Yes, I saw that after I looked at you journal and subbed :
:During veg I was 18" right now in flowering 12"- 15" and one at 20"
I have 2 more lights coming on Monday, so I will be able to adjust for each plants needs.
Here are a few pics from this morning.
The pic from post #26 was from June 6th.

Oh ok. Is that a 4'x4' tent then? And do you not have an exhaust or am I not seeing it? I just see the inline fan hooked up to your filter, but it looks to be just circulating it in the tent. That yellowing does seem to be apparent on all plants. You can try using some epsom salts (has your magnesium too) to help out with the sulfur deficiency (if that's what it is). 1 tsp/gal should do it.

I was doing the polishing method (recirculating the air) which worked great when they were smaller but now the RH is getting harder to control and I am changing the setup today.
I am using the pot lift method for watering and don't expect to water until tomorrow and adding the Epson salt then.

It's looking very healthy now, good job! Now you just have to wait for her (hopefully) to start spitting out lots of flowers, which should happen soon!

Let the transformation begin! This is the fun part, but it's not all cake from here. Just keep an eye on things like you have been, and these girls will reward you well!

I have not been able to keep a eye on my girls the last few weeks with the temp company working me close to 70hrs the last two weeks, but very grateful for the extra income.
Ok new developments.
The plant seems to be growing slow, it is 24 days into flowering and I am seeing a lot of yellowing and dropping leaves.
Which I have read is normal, but I am also seeing what I believe are Thrips, I am not sure but from what I have read it seems to be the problem.
But I am not seeing any of their black poops.

I can't really tell what that is! It doesn't look exactly like the thrips in the following sticky, but the pictures in the sticky aren't great.

Yeah, I looked at those and I am not sure but keeping an eye on things a little closer.
One plant is now yellowing and clawing compared to others, so I went looking all over but not finding the answers I was looking for.
So, I flushed the plant cut the fabric pot to see if it was root bound and transplanted to a bigger fabric pot.
The roots looked really good and I tried not to disturb them the best I could. I didn't break up the main part but it seemed really compacted.
Plus I finally was able to do the slurry test, it was 7.5 and now I wonder if I should lower the ph down to 5.5 on next watering.
I added about 2-3" of new soil on the bottom and sides and now waiting.
A few pictures.
Compared to other plant you can really see the difference.
Tent lights out getting full
A little eye candy
Nice , when checking for thrips ect , look under the leaves ,

Hello again Ruthy! I'm guessing it's still pH related. If that one plant is in the same mix as the rest, I'd guess all of their pH is out of the optimal range, yet that particular plant may not handle it as well as the others. I do have to say that last picture shows off a NICE BUD!
