Mag Deficiency or something else?

Outdoor with Promix with Gaia Green 4-4-4, 2-8-4 + seaweed tea, Thrive B1, light amount of worm castings. Rain water 80% tap water 20% (hard water), water is between 6-6.5ph, 15 gallon pot. 1 out of 2 of the same strain affected both same size pot and same feedings.

Mag def would start at the bottom of the plant.. Could be light bleaching..

Worm castings are good with dry amends.
Adding anything for microbes/bacterials/fungi's to help break down?
When was the last time you fed?
What pot size?
Do you use humic/fulvic?

Microbes via Worm castings, Great white mycorrhizae and the mycorrhizae that came in the grow mix.
2 1/2 to 3 weeks ago I fed and they been green and happily growing quickly until the last 2-3 days. One pot is a 15gal and the other is 12gal. Only the 15gal is showing the issue at this moment.

Humic/fulvic i haven't added unless it's in the soil mix that is "natural sphagnum peat moss combined with dolomitic lime stone, perlite, vermiculite, mycorrhizae, a natural wetting agent plus a starter charge of nutrients."

Looks like they're starting to get hungry then. No worry.
2-3 weeks they could be due for a top dress @ 2TBSP per gallon of medium. Remember it takes time (7-14 days for them to begin to absorb it.)

Thank you, i'll top dress today. After the last feeding it was about 8-10 days before they started showing signs they were absorbing it. This is my first try at organic growing, usually i just use synthetic nutes.

With Gaia Ive found its better to feed less and more often,say like 4-6 tablespoons every week instead of a cup a month.
Mix in with EWC and cover so its always moist,

This time I top dressed with 1/4 of the recommended amount of Gaia which i will do each week going forward. That will make it easier when adjusting of the ratio of 4-4-4 to 2-8-3 for the flowering stage.

Ive dug trenches in the soil then top water over daily just a little for a quick N boost.

Keep soil covered so the surface never gets dry,keep it alive youll get some some white fuzz,aka mycelium

I think I may have found the issue, plant is in a black pot which i had covered but wind blew the covering away then we had 3 days of sun and heat which i think may have cooked the roots. Possible?

Yes the first time i seen that I was thinking wtf is going on.

looks like a lock out of zinc, and iron from to much organic form of phos.new growth is not expanding like it should,also so slight cal,and boron,?

Hmm now that you mention it .. when I measured out the GG the last time I made a mistake and mixed in 25% 4-4-4 and 75% 2-8-4 instead of the opposite. Is the extra P in the 2-8-4 GG the cause?
