Jammy jam jam haze

Wait a bit and cut the stalk a 1/4" above where the secondaries are showing at those cotyledon leaves. Baby it and call it an early top. It's a weed, It'll survive.

2 choices with mutants. Wait and see what happens or, "why plant maybes" and pull it. Here is a link about a mutant I grew out. Chose Week 4, swipe photos to Trixie. growdiaries.com/diaries/259371-grow-journal-by-novc01

What's weird here is that it did have a growth tip, since it added a node beyond the cotys, then the growth tip disappeared... so did something drip on it? could have burned it, or it could be some weird genetic anamoly, i guess. You have 2 axillary buds, so it can keep growing without much delay. Looks like they are already fairly well developed, so the plant is already reacting to whatever the cause was. I wouldn't prune anything off now, but once those axillary buds grow into branches and those old leaves get buried, probably best to prune that off. That's going to be a tight space, but as of now they are your best solar panels, so they are integral to continued growth for now. based on internode length, looks like maybe a bit too much light early, then backed off a bit too much while 2nd internode developed as it's a bit stretched. This could also just be from a seedling asking for more light but not getting enough right away... i hesitate to say this. if you already adjusted the light, i'd stick to wait and see. If you've done nothing in regard to the light i'd amp it up slightly or get it slightly closer (distance very quickly impacts light intensity, so when i say slightly, i mean very slightly, lol). Anyway, looks to need a little more light, but nothing major. The stretch or lack of stretch is your guide to adjusting light intensity. New growth will show the results of your decisions. Old growth will remain tight or lanky but will also have some slight improvement over time once you get it right.
