Little Help.. Another Sick Plant

Just looking for a diagnosis. All of my plants end up looking like this.
The lower leaves are very yellow and the upper fan leaves seems to be yellowing from the center. Could be my LED, nutes should be fine, adding calmag.. I'm out of ideas unless this is just natural..

AGE: Nearly 7 weeks from seed
STRAIN: Sugar mango Ryder Autoflower
WATER: Bottled RO water with 1 tsp calmag
POT: 3 gallon fabric pot
NUTES: Happy Frog dry nutes mixed into soil, but I have also added some liquid Floranova veg nutes in case it is N deficiency.
SOIL: Soil is Ocean Forest mixed with 25% perlite + Dolomite Lime
PH I have not checked the PH because the whole goal was to use organic soil and organic dry nutes to allow me to grow "water only"
LIGHTS
Apollo 50 true watts LED
3 10w LED lightbulbs
1 26w 6500k cfl
TIMING: Been running lights 24 x 7
Light Distance is very close. Top LED is within 6 inches and side LED's almost touching
TEMPS high 70's


The leaves have a bit of nute burn. Even the slightest amount of nutes would burn this strain. It's the strange way that the leaves are yellowing from the center outwards..


Lower Leaves
The strain is supposed to run 8 weeks from seed under 24/7 lights, but I can't see it being anywhere near close to done. Looks like 4-6 weeks from finish.




Tent Setup (This is an older pic from a few weeks ago)

you are running out of gas. You will need to feed these plants until finish. Any general plant food at this point will be sufficient. The next time you plant, line the bottom of your smart pots with some nutrient rich earthworm castings and perlite mixture, sort of have a reserve of nutrients for the last two weeks. The lack of nitrogen in the fan leaves is really not a concern. Look at all of the trees that change the colors of their leaves for months.

And you should still be making sure that your pH levels of your dirt are in the happy range. A little pH goes a long way

Yes, in the lower portion of the pot I have added the Happy Frog Dry Organic nutes... I also give her Big Bloom..

Today I gave her 1 tsp of Floranova grow nutes. I'll just keep feeding her that until the end.

Ph definitely has to be checked and adjusted if not right, every watering and feeding. Its a BIG and common misconception that you don't have to ph for soil but it is VERY un-true IMO

prolly just your auto flower ending the end of its cycle

I hope not, There's about 6 grams of bud on her I don't even think I'd bother to harvest
