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 4y 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.

Seedling leaves are discolored and starting to curlNot sure what the issue is here. You can see it evolving over the past few days (Sept 29th - Oct 2nd). The leaves are discolored, light, almost yellowish in color. And one is starting to curl. There are clear images of this in the post above. What's going on here? Thank you!Leaves. Curl up

So... What's happening here then?I'm a total novice whose not having the best luck lost alot of my first proper crop to mold but still have 3 going strong. But this is a new one on me, so the leaves have curled back on themselves making them thin and finger like, so what have I done or not done to cause this? Xx

What is this deficiency with DWC, GH Trio, flower day 19I'm in about day 19 of flower and a deficiency just showed itself in the last day or so. It's in the last 3 photos of week 3 of flower in my journal. Any ideas on what it is and how I could mitigate the problem? Grow has been essentially flawless up to this point, thanks!!
