Yellowing leaves on early stages of flowing auto

Hiya I noticed alot of yellowing on my leaves with abit of rusty looking browning on some over the last 2 days along with slowed growth am wondering if anyone with more experience has any idea what the problem could be. I'm growing in bio bizz lightmix soil with mars hydro 300w eco light and greenhouse powered nutrients, am watering when it seems needed, was looking healthy to a couple of days ago so not sure what's happened, have got temps of 69-74 and humidity at 48-53%. Any help much appreciated will attach some pics, am thinking it might be nutrient burn, if so should I just flush the soil?

Welcome. Congratulations on making it this far.

are you using any nutrients? Looks like she may need some. How far along are you?

leaves will naturally yellow as you get near the harvest window.

positive vibes my friend :Namaste:
 
Yes I have been using greenhouse powered nutrients lightly with every water since like day 27, just started on the bloom nutrients, has been 40 days since she sprouted through the soil now, was expecting leaves to start dying off at some point in flower but thought it would be nearer the end is this normal at this stage then?
 
Thanks for recommendations have given it a good water with nutrients, have just always been cautious of going over board as always see people saying how over waterings alot worse than under watering, and obviously autoflowers are ment to be easy to give nutrient burn and would rather possiblity get abit of a smaller yield than kill it off.
