Hi, first time grower here so early days, but one seedling has develpoed strangely.
I planted 4 x auto Dwarf seeds (regular, not feminised, indoor/soil/led 120w) and all are okay except one which seems to be 'throttled' at the top of the stem since a few days after germinating, as if I had put a tiny inflexible band there, if you see what I mean. I can't find anything online to say if it is a nutrition difficiency or any other reason.
It's now about a week in and the cotyledons and first proper leaves have appeared, but are tiny and not developing like the other three, stunted. Then the stem swelled up to twice the thickness and stopped gaining height at about 2cm. The other three are at least double that height too. I gave it about 5ml of water earlier and the swollen stem has now split veritically almost the whole length of the stem!
**See photos below**
I imagine its days are numbered but I'm going to leave it growing to see if is repairs itself or dies.
First question: Anyone know why this has happened? I'm guessing maybe it was a defect waiting to happen from before germination but it's literally a wild guess based on zero experience.
Second question: As it's basically a write-off, would it be worth very carefully extending the split upwards (with a surgical grade blade) to the throttled zone (but stopping before the leaves) in the hope that it may ease or unblock the xylem or whatever, and maybe it will heal or recover to some extent? Or would that be sudden death for a week old baby?
Any answers, guesses, or encouragement to unleash the blade welcome!
edit: when I say exten the split, I mean just lightly cut just the outermost 'skin' on the stem where it is tight, I don't mean cut in as deep as the split.
