Pretty lanky and suddenly slower

[frankthirtyspears]

Hi guys, here is my royal critical auto, she's 16 days old and she's growing pretty slow recently even if i can tell she's still growing. I've thought about a nutrient deficiency since the soil is very light and i only used these https://www.royalqueenseeds.com/growing ... ition.html , but the leaves (at least to me) seems pretty normal. She has had an overwatering problem for about 2 days with some fungus gnats but i've sprayed the soil with some neem oil and started watering way less. She also might have had a bit of stress due to my grow tent being build while she was growing and so being subject to a few lightning schedule and heat variations. So after all these considerations there is something that i can do in particular to make her recover/grow faster and stronger like some kind of nuts or other stuff or i just messed it up and stunted the growth permanently? I'd be glad to hear any way to solve at least a bit the problem if it's still possible. Thanks as usual guys and have a nice day :)

I'm growing Royal Jack at the moment. At 16 days mine was pretty much identical to this. However it has really rapidly grown in the last week or so. Picture below was yesterday (~28 days)

Looks like you may have some environmental issues buddy. What's the temperature like in your room?

The temp is 23-24 °C at day with about 50-55% RH and 19/20 °C at night with about 50 % RH

Also one of the sucker leaves is pretty yellow, is it because is covered from the other leaves and don't receive light or another strange problem?

The yellowing will be underfeeding. Your environment sounds pretty spot on so let's look at other avenues. What media and what are you feeding them?

The media is BioBizz light soil and since i wasn't really sure about the nutrients i just bought some organic nutrient pellets from royalqueenseeds (which i linked before) and mixed them in the soil.

Also wansn't meaning the sucker leaves yellowing but the cotyledons. Sorry but i've messed up the terms a bit.

Looks fine to me tbh - much wind on it? Wind will fatten the stem up :)
