fox farms ocean forest? or happy frog?
ocean forest is pretty hot, how long has it been in the soil?

you need a base nutrient system.
Roots excelurator is an additive and meant to be used with the Soil A+B parts of the house and garden line not by itself
it has a NPK of 1.6-0-.7
calmag is 2-0-0, and meant to supplement a main nutrient as well
silica is also an additive, and depending which product you're using, not much p or k

so your missing phosphorous completely, and pretty low on potassium. if the plant has used the nutrients that were in the soil, it makes sense phosphorous or potassium deficiency. most likely phosphorous since you're giving it none. usually presents itself as that mottling pattern on lower leaves.

overall your plants look fine to me. but in the future you'll need a complete nutrient program with N-P-K and all the micros and macros.
i would ditch all those nutes and get a 1 ingredient solution, such as megacrop by greeneaf nutrients.
or, if you wanna keep using those, i would buy the Soil A+B main parts to go with them.

the ffof is whats getting you through right now possibly.
