Welcome to AFNWell I was feeding them big bloom and grow big from fox farm up until 2 and half weeks ago. I stopped cause I started to see nitrogen burn. I noticed the leaves looking like the pics above maybe a week ago but idk how long been there. I started them on tiger bloom 3 days ago and I started at 1/4 the recommended dosage. If it looks like the nutrients aren't hurting them I was going to continue it weekly with at least one regular watering in-between the nutrients.

What is your PH? Kinda looks like PH fluctuation. Is the discoloration everywhere or isolated to the older lower leaves?

Are you following the actual feedchart? https://www.thegrowshow.org/fox-farm-feeding-schedule
I'd go by ppm/EC rather than "1/4 strength". According to the feedchart above,
at 100% in early bloom is around 2.5-3.0ec. I typically aim for 1.0-1.2ec with my autos during that stage (assuming starting water is 0) so 33-40% strength may be a good starting point.Plain waterings in between feeds is a good idea, but the key is to stick to the ratios established on that feedchart, and just adjust ppm/EC as necessary. And everything you pour into your pot should be pH adjusted to 6.5 or so, ideally.
PPM, pH and relative N-P-K-Ca-Mg balance is the name of the game when it comes to liquid nutrients. If you haven't seen it already, @Mañ'O'Green has a pretty great write up here: https://www.autoflower.org/threads/a-word-on-nutrients.82004/
