from what i learnt there check your ec levels, dont over do the potassium it locks out calmag or something like that if you use too much.

Yes. The plant needs magnesium. Epsom salt or magnesium sulfate works well for this. Use one tablespoon per gallon of water. It can be foliar fed by spraying the solution on the leaves, or it can be watered into the soil. I usually water it in, but foliar feeding is faster. I add Epsom salt (and gypsum and rock dust) by topdressing before watering about every two weeks.

Thanks for the reply guys I'll add the salt. Would you add it to straight water and PH or can I add it to the nutrients? Or I can just add cal mag right?

Jj,

I suggested the foliar application of Epsom salts but be carful. more is less. 1-1/2 tsp/500ml spray bottle.

If it’s a magnesium deficiency the foliar application will remedy the leaf appearance very quickly.

Epsom salt is one of the easier amendments to add. Foliar feeding takes effect fastest, so that's an effective way to start. I top-dress it. Watering works well, too. I top-dress it with other amendments so I can add everything at once.

So I can do 1 tablespoon per gallon for foliar spray? And stupid question do I need to Ph that?
