Have you flushed at all yet? The FF nutrient schedule calls for a sledgehammer flush periodically.
If not, I’d flush and then resume feeding. Here’s how to perform a SL flush, from FF:
Thank you for contacting FoxFarm, I’m happy to help!
To perform a flush with the Sledgehammer product, you will want to prepare the mixture at a rate of 2 tsp per gallon of water. You will use the Sledgehammer standalone. Pour the solution over the soil and use about twice as much solution to flush as you would if you were normally watering or feeding. For example, if on a normal watering you use a half gallon, for a flush you would use a whole gallon. Once this is done, let the soil dry completely. After that you can pick up with the next feeding as scheduled.
If you have any other questions please do not hesitate to contact us.

I have not flushed them yet. Is it necessary to flush with the sledgehammer? I would think just ph’d water and a feeding would do the trick. I will try one plant and see what hapens. Thanks for the advice.

Well, the Sledgehammer is made from saponin that is derived from yucca, and is specifically designed to breakdown the leftover salts from their nutrients, so I suspect that (at a minimum) it would be much more efficient than water. Water might well do the trick, but I have no idea how much.

This. You don’t need sledgehammer, but it’ll save you a ton of water. Think 5 gall of soil, either 2-5 galls of water with sledgehammer or 10-15 without.
They look to be a tad N burned (too much Nitrogen). So lowering the ppms of the soil would be my first step.
