Magnesium Deficiency?? Need some help.

Having an issue with my transplanted MUMS I transplanted my mums from sitting in pellets in 6in RW and i needed to get them with the rest of my plants on a 2hr flood.

I put them in buckets with RW above the water line. My leaves have started to look like PIC below yellowing leaves along with being very papery and rough in texture the plant seems very weak and just not feeling well in general I believe its Magnesium deficiency.

I am thinking flushing the RW just because of the buildup of crap in it and see where that gets me.

What are my options to fix this? I am kinda at a loss here.

I am using Flora Nova VEG 1400 PPM it was 3 hr water cycle 24 /7 but just moved it to 2 hr water and 18/6 light and it is always 5.8PH

Thanks

No I add a small amount of sea weed extract but that's it. And i have been doing that from the beginning with no problems. All the other plants in the system are fine its only the large plants that i transplanted are showing this.

well you def need to use cal/mag, that is one of the reasons your fan leafs are falling off.

Fan leaves are not falling off.

i have the exact same prob with my plants. leaves look very similiar to yours. Also the new growing sprouts are a lime like colour. very weird colouring.
I did some research and i'm pretty positive its a mag def. probly caused by a Ph imbalance or cause the nutrients being used dont contain enough magnesium wich alot of them dont.
I'm gonna water with 1 tsp of epsom salt per gallon of water. see what happends. i was told after approx. 4 days the plants will look greener, if that was the problem.
