Nutrient deficiency in one strain?

I've got 3 strains going right now, all flipped to 12/12 6 weeks ago. Gorilla Cookies and Gelato Cake seem to be thriving, but my sherbet looks like it could be happier.

I'm growing in Sohum soil, watering with tap water ph'd to around 6.5. Feeding roughly weekly with a half dose of terp tea, top dressed. Running a Mars hydro ts3000 light.

I do think I had it a bit low and got some light burn, but I've raised it up and the damage seems to have stopped. This is starting low and going high it looks like.

Magnesium deficiency. A little late to address it foliar spraying. Maybe too late to water in but I’d try that first.

Epsom Salts. Needs it badly. Sulfur is also responsible for Terpene Production.
Id give a small amount with each watering/feeding. Mg deficiency is the #1 container grown deficiency. Weed also is a high Mg/Sulfur consumer, and also Potassium.
Id probably give a strong first drink, and then cut back. 1x TBLSP per 1.3g water, then Id try 1-1.5tsp per watering.

Hopefully the top dressing will correct the deficiency.
