Auto flower plant discoloring, any suggestions or advice on how to fix?

Hey there, I hope all well with everyone!! This is a end week6 start of week7 update on my first autoflower grow.. more problems with the same plant this time it looks to be a toxicity?? After getting plants dried and properly watered, NYC diesel has caught up to the fast buds Sour Diesel.. but now fan leaves are starting to show discolor becoming brittle and tips have been cuffed since beginning.. I have top dressed both plants with build a soil top dress feed at week 3/4 when pistols first started and then again in week 6 any suggestions or advice? Here’s some updated pics

fast bud sour diesel.. the plant that gave me the less stress, growing good in my rookie opinion.. receiving 1.5 liters about every 3rd day

You're locking out from too much food.
Easy to tell by the Nitrogen claw and lockout symptoms in the leaves.

What size are your pots?
Are you watering until you see runoff/drainage?

Thanks for your response! I was thinking the same I believe I top dressed too much maybe too early with an already hot soil of FF .. my pots are 5 gallons but weren’t full from the beginning I recently added more soil to put to fill them out, which may has caused more trouble.. and they are getting 1.5 liters at the moment this light run off at the bottom

If they're all 5 gallon, I'd give them all the same amount of water. Aim for about 5% pot volume in runoff, little less doesn't matter.
Just keep it up with plain water.
They should start getting better within a couple waterings.

In your opinion is the 1.5 liters good? Or should they be getting a lot more at this week 7?

It’s all about the size of the plant as well as the pot.

Big pot/ big plant needs lots of water. Big pot/small plant doesn’t need as much.

Your root system got stunted early on from hot/dense soil and also perhaps inadequate watering amounts/frequency which is needed to establish a good rootzone. At the end once harvested if you rip the rootball out of the pot you’ll see just how small the root system will be!!

1.5L may be about right considering the size of the plant

For me in 5 gallons 3-4L was about right. But the plants were much larger
