So, I think I actually have something going wrong! What does it mean when the leaves start going lighter yellow starting from the stem up the leaf?
What does it mean?

New growth is normally a lighter color, give it a couple days and see if it doesn’t darken up. It takes a couple days for new chlorophyll to develop. It it doesn’t correct itself, or gets worse then it’s either a non mobile element (Mg, Ca, S, Fe, etc) since it’s starting at the top. Lastly, it could be light burn (but I doubt it).

Light is like 30 inches or so away. 150w Mars Hydro TS 1000 at 100% power. The water gets pH'ed to 5.8 like this has me stumpped, and I am fairly sure this is the first time the new growth has been lighter. But I could be wrong on that.

Early leaf pigmentation as stated. Carry on.

If you're in soil, then I'd up the PH just a hair, to 6-6.2, in coco, 5.8 in perfect.

Doesn't look like that to me. Looks like a ph/feeding issue to me.

I'm in the "looks good, carry on" camp, but out of curiosity, what is the ambient temp during the day and night and have you started feeding her yet?

Yep she has been getting fed for 15 days. temps around 80 and lung room stays about 76 at the lowest.

Could be an iron deficiency if it's the upper leaves.

Ok … break out the PEE … stat.

Close, I gave her a Heavy Feed. 6g of Megacrop Instead of 4 and A heavy dose of Molasses(high in Iron) Double checked the pH and pH is not the issue, its spot on at 5.8.

If you take a little read through the organic forum or any of the organic tea threads, they generally advise against putting molasses into your feed, and instead recommend using the molasses to make a tea and then feed with that. The reasoning was: the plant doesn’t directly use the sugars but the microbes do. Dumping a pile of “food” like molasses/sugar into the soil system will feed all the microbes at the same time - both good and bad - and it’s possible that some of the bad microbes might outcompete and reproduce faster than the good ones. Making a good tea with compost or worm castings is like culturing tons of exclusively good microbes, and then only dumping those into your soil. I used to feed with molasses in my mix too, until I read about it and started watching soil-science videos on YouTube.

Gotcha, Its been workin so far, so I have just been running with it. I read Molasses once a week to feed the mycos so that is what I have been doin.

Yeah its why you use your super worm tea within 24 hours ideally as well cos after that your just growing protozoa not what you want
I use it but not as often as weekly every couple of weeks is ok ime

This is a PH problem clearly, you double checking to see it's 5.8 don't mean it's good or it will suddenly work.
If you use a peat and coco mix then go 6.2-6.4 and they will get back to their natural color.
Also what @Phytoplankton noted is right about lighter color in new growth, but yours looks a lil too much for my comfort.
