Hey guys! It's my first grow and I'm having issues with my plants which are 1-2 weeks into flowering. Their showing signs of light green/pale lower leaves. Moreover, the leaves' tips are burned and as time goes on the leaves beginning to turn completely yellow and die. Pictures are attached. If you could let me know what you guys think the problem is I would greatly appreciate it. Thanks!

Did you just transplant them prior to bloom? I wouldn't be too concerned unless it progresses.

I didn't transplant them and its been spreading to other fan leaves thats why I'm getting worried. Moreover, the last time I fed them was probably about a week ago at half strength with dyna gro. I normally feed them nutes at half strength every other feeding, but the problem that is occurring right now looked like really bad nute burn so I gave them a good nontreated watering like 5 days ago and it seems that it hasnt fixed the problem and only made it a little worse. I fed them at 1/4 strength yesterday scared that it might be burn still, but now I'm thinking otherwise.

Here's a better picture of what happens to the leaves as time wears on. Notice how the tips get burnt to a crisp. Moreover, she has red stems.

Ive noticed with fox farm is that at or around 3 weeks the soil needs food. Do you think the plants are hungry? Im not seeing too much tip burn on surrounding leafs, which is something i look for when i think i might have over fertilized. Wait for some others to say something so you can confidently make your move in the right direction. Theres a few guy/girls around here that know plant issues like the back of there hand.

looks like you need to increase your feeding amount and/or schedule. from what i can tell in the pictures, the growth on the top is coming in fine and it's just at the bottom. i use HF soil too, and as @a mongo frog said, usually around 3/4 weeks, i need to start feeding too until they get transplanted into super soil.

a couple a side notes to consider also, bottom leaves will die off so some of those leaves were not a big deal, as long as the new growth is good and the bulk of the plant is good. Oh and some bottom leaves will look retarded sometimes, no big deal either.

I recon it's ph imbalance maybe mate. If your ph is not right too high or too low then it causes that.. No neuts will fix it. What I would do is give it a good watering untill your water ph matches your run off then go on from there. Hope it helps buddy
