Help with yellow leaves please. Week 6 Flower

[luckytrees]

The yellowing leaves started on day 38 and has increased each day since. I'd say I'm still about 3 weeks away from harvest, I don't really want to but I'm thinking of doing a flush a week early just in case it's being caused by salt build up or excess nutrients. What do you think? does it just look like normal yellowing at the end of flower or something i should be concerned about? I was reading about sulfer deficiencies and it seems like it could be that. So I think I'm going to add a tablespoon of Epsom Salt to a gallon of water. However, I just fed them a couple days ago and will be watering today or tomorrow. Should I just add it to the water or wait until feeding day and add the Epsom Salt to the nutrient mixture? It's progressively getting worse, more so on blue dream than silver haze but I'm starting to see the same type of yellowing on silver haze. I want to fix this as fast as possible, being this close to harvest is freaking me out.

Don't fight the fade.

Right on man, thanks. I was thinking that it might be fine, but as the yellowing continued I started to wonder what 3 more weeks would look like if it continued at the rate it was going.

Here's day 42 of flower, I'm noticing some burning on some on silver haze leaves and wondering if this might be because of light or nutrients. I also put some pictures of the bottoms of my pots i have not done a flush throughout this grow and I probably should have (they're completely white on the bottom).

if the lights are too bright they will stop uptaking potassium and this yellows the leaves along the edges as opposed to nutrient burn which starts at the tip , the ones that are in full bud seem to be able to handle it at the moment but you might risk burning off your terpines . my plant which is nearest my small led light was sticky last week (2 weeks before harvest ) and now its dry to the touch .
