Day 9 - first time grower - concerns

dont worry the plant will grow just fine, in another week you will see, another 2 weeks you will be like wow, looks good dont stress it

is it always wet? if so, that can cause weak stems.. can be microbial growth getting an opportunity... Too much light can make aplant wilt, but doesn't seem to be the case here. If it is stretching, get that light closer -- that too can help thicken up stems. If each plant requires somethign different in that regard, raise some up so you can create the variance of light intensity you need. looks overwatered, though.. your recent behaviour will eliminate that or not. As far as leaves and prettiness early on... care more about vigorous growth... is it growing quickly? all is well, even with a couple blemishes on first few sets of leaves. If you've been fertilizing, don't fertilize seeds first 2 weeks in future... ease off in that case for a bit. Many variables to consider before doing anything or adding anything.

Thanks @gmslave when should I start with grow nutrients

Yes looking good bro. Let the top of the soil dry in between waterings. Cheers
