New Grower Is Anything Wrong With This Plant?

[Sunny747]

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.. I might think that the plant is just nearing the end of it's lifecycle, but there is about 6 grams of bud total.

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..

Any thoughts? I added 1 TSP (Full dose) Floranova Bloom today.. Maybe she was sensitive to nutes in the beginning and is now eating them up..

Looks hungry bro, probably lock out of some kind. Even with organics you should check your pH to make sure something is not way off when the plant is not well.

How would you suggest that I check the PH? Runoff?

You can do that yes, but not the best way. A soil probe like an Accurate 8 is best. If you check run off, you will need to know the pH of the solution going in.

Looks like nitrogen def.Try giving it some higher nitrogen nutes mixed with water.I would also cut your lights on time to give them a rest period.

Just to follow up on this in the case that it might help someone else... I pulled out my PPM pen and I was definitely under feeding. I upped my nutes to 1200 ppm and it really made a difference... I'll always use my ppm pen from now on.. See the difference in the color of the leaves... Hard to believe it's only been 9 days since my last post.. She's completely matured since then... She's ready for chop. This is end of week 8..
