No. I haven't. Feed every other day. Water feed water. Off and onI'd be more worried about the yellow leaves hosting those spots that are not photosynthesizing the light anymore.
Have you been flushing?
Ff soil 1/3 perlite.. feeding ff bloom. 6 ML...with 3 gallon water. Every other watering...hlg 550r spec...with uva bar.Are you in soil?
Better yet, just provide as many details as you can about the grow.
In 5 gallon pots. Its dry. On the second day. Always. So I should let dry out out. ?Well, there's the problem. You're overwatering. Plants in soil don't need water/food on a schedule, they need it when they've drained the soil of the last watering.
