What is causing this in my autoflowers?

im sorry if this seems genetic, i posted this in a autoflower forums the other day without much help and have used this site many times during my non auto grow, this is my first auto grow and i seem to be running into issues. it should be noted someone had said that the death to bottom leaves was natural due to age and where they are on plants and moreso top of plants appeared to show signs of underfeeding, seeing as how i was feeding plants 1 gallon total amongst all plants per week. ive just fed the plants an entire gallon amongst all of them at full strength for week 5 earlier today. i will post a photo of the feed schedule. todays feeding was 6PH and 1000PPM



Problem: In the past three days im noticing alot of my fan leaves discoloring and some dying off. This started probably 5 days ago on lower leaves in canopy and i thought it was due to lack of light so i trimmed dead leaves off but the problem seems to be spreading. it should be noted as well i woke up this morning and found holes in the leaves so im thinking my cat got in and had a snack?. but as far as the discoloration and dying im stumped.

Medium/grow method: FF Ocean Forest

Feed: and supplements used: Fox Farms Dirty Dozen, 2x per week. typically at 1/4 - 1/2 scale ill attach photo of feed schedule mix. note im not using the open sesame. last fed around 3 days ago i mix 1 gallon per week so they get fed .5 gallon 2x per week.

water source: Distilled water only ever PH balanced when mixing feed in separate gallon probably fed 3 gallons maybe a little less every 2 days divided amongst the plants.

PH in the root zone: test from last night on most effected plant appears to be within 5.5-6

Strain/age: Most heavily affected are 2 GDP's from MSNL they are 5 weeks old. however starting to see some discoloration on my big bud also from MSNL and is probably 4.5 weeks old. they are going into second week of flower.

light used: 2 plants on right ( GDP and BB) are under 600w LED putting out " actual power" of 260W 3 plants on left ( younger auto widow, GDP and alightler older AW) are under 600w " actual power" of 260W and a 1000W "actual power" 200W LED running 18/6

Climate: climate stays around 80F with two fans circulating air.

Additional info: Last feeding they received probably 3 days ago was slightly stronger then ive been doing, i believe i went full strength on this mixture but after feeding i fed pure distilled on top to dilute the feeding. after doing research i believed ( i could be wrong) they can handle full strength nuts in the bud and bloom. i will attach feeding schedule photo as well. It should be noted that the big buds already starting to produce crystals on leaves of bud site whereas the GDP's have not.
