Swollen nodes need help

So here is my deal been reading a bit. And some say this is good some say bad. Can't figure it out.plants are on a 18 hr light schedule. Unknown seeds cause they came in weed I bought.I topped it today 01.6.2020. Because several people said do it. This is my first real grow with a tent and lighting .I'm on a 400 watt mh set up then 400 hps for flower.may try to get a 600 but not sure yet.some light has been leaking in from the bottom of the tent but it's in a dark garage that isn't opened much and a 60 wat bulb.I have since fixed the leak best I can.2 of the 3 plants look fine this one has stayed short and bushy and I'm not sure if I need to prune it or what . Below are the p8cs of my plants . And helpful advice would be much appreciated. Also the plant with the swollen nodes half way up the plant as seen in the pics it's normal not swollen

The smallest plant in the back is the one with swollen nodes it seems to always be wilted no matter fed (fish fert) or water.

There's soke old threads on here about it. Seems either sign of a healthy plant thats been topped? Or building extra strength to support the buds coming. Just what I've read. Ive had 1 do this before and I didnt have any issues.

Sweet thanks so much I just signed up and was having issues finding info on it.it wasn't topped I germinated it from a seed.I topped it today from several things I read but now I'm wondering if I #$$%ed up by doing it .but it's my first real time.I did one before start to finish with a low wat led for full veg as in a shop light lol the flowered with 150 wat hps.didn't get much lol.anyways I did top 2 plants today left the big one alone so should see in a week or so.

This could be a dumb question but would that mean it's a higher chance this was an auto flower seed?

If it was an auto it would automatically start flowering between week 3 and 5 ish

I generally top all my plants but theres always a couple that lag behind so I leave those ones be. It will most certainly increase yeild

Ok I wasn't sure I'm still kinda reading on auto flower stuff

I ran an auto a few months ago and it started shooting pistils under 18/6 light at about week 3-4

So they should be fine even though it's a little later? This pic is from yesterday

OK yeah it's been under for a little over a month now so it isn't one.like it may sound bad but so far all my seed are what's been found in my meds

I'd like to find some auto flower though

These were out of a midgrade bag

Oregon elite seeds. They have buddha magnum autos for 25 bucks. Bunch of others but I had gotten those .Can call with credit card easy and fast

The extra swollen nodes are usually caused by air movement & genetics.

100% normal

Yes those will be perfectly fine they're only one internode further than what I personally top at.
