Raspberry cough

Nirvana Raspberry Cough Fourth week of flower.

I just fed all my plants a full nutrient schedule and they are all OK except for this one. Funny because Nirvana says this one is really easy to grow.

Fox farms ocean forest 7 gallon
RO Watered ph 6.1 with calmag added about a gallon of water a day
Technaflora nutrients, feed water water feed water water cycle
Growers choice roi e720 1000watt hps equivalent at 18"

I had read on the growers website that I could lower the light to 6-12" and tried it for a day but noticed burning so I raised it back to 18-24"

I have other strains in the tent and they are OK, one is blackjack and it has a few leaves with similar symptoms.

I thought it was light burn but it seems to be getting worse, so next, potassium deficiency? Seems to be worse after the last feeding. Maybe flush it and start with the watering then feeding?

Thanks for any help you can give me with this.
