Leafs browning and curling, first time grow OG Kush Auto

First timer here and just finished up week 8 (starting week 9) of my OG Kush Auto grow from ILGM. I am growing in Happy Frog soil, light is SF1000 and humidity around 55% and temps of 73F.

My plant is presenting numerous problems including burnt and curled tips, browning of leaves all over, and yellowing of the middle leaves of the plant. No nutes until the start of week 3 where I introduced Fox Farm products. I never worked up to over 1/2 strength of Tiger Bloom and Big Bloom, only applied once a week and watered between feedings so if this is nutrient burn I am pretty disappointed as I thought I was being pretty conservative with nutes. I had not been PH'ing my water until recently and when signs of nute burn started to appear I flushed immediately using "Sledgehammer" flush (about 40% run off) and PH'd the following watering (my tap only needed about 1/4 mL of PH down to get in range).

Trichomes still clear and hairs starting to change color. On one positive note the buds still smell good.

Do I just let this ride? Almost every fan leaf has browning and curled tips so I don't think I can just trim it away.

Appreciate any help you can offer

Happy frog claims it is a sit back and watch em grow medium and you jacked up the nutrients and burned your plant
You can’t reverse what is done and flushing that soil will just release more nutrients
Chalk it up to a learning experience
And WELCOME to RIU

It is my understanding that HF is considered a pretty tame soil and Ocean Forest was the one considered "hot." Given that most nute recommendations you can find on the Internet state to apply at 1/2 strength I'm just surprised I got this amount of burn when only giving 1/8, 1/4, and eventually 1/2 doses every other watering.

It still claims to have the necessary nutrients and not every batch is tame

Your issues speak for themselves

Makes sense. Would you recommend trimming any earlier or just letting it play out? My plan is to just continue watering with PH'd water. No nutes.

I don't recall being in that position as I only use pro-mix
but it is worth a shot for a few weeks
