New Grower New auto grower- greenhouse

[juanpelotas]

Hey guys!

I was wondering how this seedling looks to other eyes than mine...
Last night I fed her about 1/4 strength Alaska Fish fert on a light soil made of a mix of OF and some recycled soil.
Did I burn it? This morning showed up a little stresses?

Looking for advice as I am pretty new with autos.

It's an auto Somango from advanced. They're under 20/4 light cycle with LED+CFL lights in a small starter greenhouse outside. I'm in the bay area and it gets barely cold during the night (46f last night).

Thanks in advance and peace!

Hi man!, go really slow on nutes with autos, that's the first lesson I learned here, if not you'll probably stunt it! Flush the little one with plenty of pH'd water or distilled, ROS water and she may recover, keep her ONLY on pH'd water (without chlorine) for 10 days, then start slowly on nutes. Also, check your pH, could also be a little hot I've heard with OF

Thanks for your feedback!
I'm getting my pH meter today.

Do you usually use pH up/down from GH to balance pH?

Is there a more natural product out there?

No, I only grow organic so I can't help you with that man! I balance pH adding dolomite lime to bring it up when I prepare my soil, leaving it around 2-3 days to equilibrate before throwing the seed. Then I go checking it, and I use alternatively recovered rain water (usually pH 6.5-7) or aerated tap water (pH 7.6-8) to regulate it, but unless something weird happens I don't have pH issues.
