Auto flower leaves yellowing bottom up

[AgedMaster]

skunk#1auto

2nd week of flower
13ltr fabric pots
canna a and b canna boost
canna coco pro plus
feeding at 18c as its summer
starting water 268ppm truncheon

My problem is leaves yellowing at bottom i think i might need to feed more as i got a little nute burn so i backed off. i was feeding 1.4ec but got tip burn so i lowered to 1.0 tip burn has stopped but leaves are yellowing. I thought i would ask here first before upping feed again. Its my first time growing autoflowers not sure if they start to yellow this early there a 8 week flowering strain

other than bottom they look good there 4 and a half ft tall

Others may say different but I wouldn't worry too much about those very bottom leaves. Common for them to fade at this stage. Probably not getting much light down there. If it starts moving further up the plant then I'd say look at upping the feed. They look great.

Hiya
Perfectly normal, don't bother upping your feed for lower fan leaves
Some autos I've done drop all their leaves in flower but produced great bud (Strawberry Gum, Cosmic Bomb, Space Cookies) so fret ye not Brother

thanks pal i asked alot of people about them before this and they all told me most autoflowers dont like ec above 1.0

Correct, there is no point trying to stuff an auto with nutes, you run the risk of doing more harm than good
I am using frass/myco on my current grow so even 2-3ml/L is plenty enough to keep em green
BTW Cannazyme should be used with Boost, plus PK week 3-5 of flower
Gonna get slapped here, but have a look at Bud Candy and Flawless Finish - you'll notice the difference

I only use Rhizo once, at about 2 weeks from seed/clone
Too much can bugger up your pH
