We should be able to get you sorted back, just watch for a reply from Waira or Namvet

Looks like sulfur deficiency.

Zinc , sulphur , magnesium ?

Sulfur , zinc is micro elements they need in very small amounts , issue with this elements can be caused by ph problem or excess of another element.

My 2 cents would be Mg deficiency. Need for Mg is increased at this stage and also because of the leds tend to increase the demand. Bit untypical symptoms with the very center yellowing but we can observe the stripes. Zn deficiency typically would have bright yellow in the ends of the leaves and we cannot see that happening.

A good calmag product would also ensure a healthy balance of iron and ca.

Calmag arrives tomorrow will dose them up , will it hurt to give it to the ones that arent showing deficiency yet ? Prevention better than cure?

Definitely do that...preventative action is far better than trying to catch up!! Agree magnesium.

Looks to be a zinc deficiency caused by a lock out in the ph range. Do you know what your PH is of your watering or in pot? @Waira or @namvet25 might be able to help you along more when they check in.

I watered this morning plain water at 6.0ph and the run off for both the deficient ladies was 6.4 so im gathering at the root they are fine now, just need the calmag to arrive and get back to feeding them

I think this is a micronutrient problem. The addition of a product such as MicroBlast covers a wide range of micronutrients and is very effective. I have used it for years every time I see micro problems.
