What is this deficiency please:
It’s only on some leaves, I went ahead and gave mag cal plus to them tonight just in case. Otherwise there is slight bite burn to the tips of most leaves :/

Magnesium.
Symptoms show in the leaves 2-3 weeks after the problem starts in the root zone.
Remedy will take 2-3 weeks to show in the leaves once cal/mag is increased.
Cal/mag weekly is probably where you are at.

Are you in flowering? If so, it's normal for the plants to change their colors; usually, if fed properly, they should take on autumn colors in the last two weeks....from what I see, it might look like a phosphorus/potassium deficiency...if that's the case, giving Cal Mag will only feed its hunger for phosphorus and potassium because they are closely related nutrients....they work in symbiosis...if you're in flowering, I recommend adding a high p/k nutrient and once a week supplementing with Cal Mag...what substrate are you growing in? What stage are you in? Be more detailed so I can help better.

Use Epsom Salts
Mix 150ppm 2ur tap..
As use as a foliar spray. U want to lower ur lights while de leafs soak it up. This will be a much quicker intake while waiting on the sub 2take it

looks like it could be a minor iron deficiency mate
iron is an immobile nutrient so must be added to the plant
iron chelate is good and can be used as a soil drench or foliar spray
