Hi there. You may be running a tad to high on the Ec for an auto. I find if I push above a Ec of 1.4 I get problems.
Organomananswered grow question 5y ago
This is nutrient burning, not a pH issue. Autos don't seem to like too much feeding in my experience.
True nutrient lock out does not occur unless the soil is above 7.5 or below 5.5.
Hope this helps, Organoman.

Twisted, yellow/brown tips.Hi,
My plant has shown signs of a nutrient excess throughout its complete cycle. It keeps to the tips of younger the leaves that have a tiny twist in the end. I don't think it's the light as it also affects leaves in the lower canopy. I keep on flushing but nothing changes.Leaves. Tips - Burnt

Slight lightburn?First pair leaves on left plant turn slightly lighter, first sign of yellowing a bit. Also I think they are a bit in a V/praying shape.

Other suggestions maybe?Leaves. Curl up

I see that there are yellow leaves with brown spots, the tips of some leaves are "burnt", and I also could see very small flies
I think they were "Fungus Gnats" and that they may be the cause of his yellow spots, am I right?

Why have the leaves on my plant turned pale and crispy?4 weeks into veg with auto and all of the leaves (including new growth) have turned very pale and dry, starting at the tips and receding rapidly.
I’ve used the same two part nutrient solution in the same quantities as I did with the previous same auto, so Disease maybe?Leaves. Curl up
