Questions about 3 HSO Bubba Kush autos

[Crowboy]

All three are slightly different structure. All are 15 days old from popping from soil. One slightly larger node spacing, one squat one with less node spacing, and one half the size of the other two. Have had lights at 24”. 1500w Phlizon newest 10w LED. Is this genetics? Lighting differences, or something else?

Does anyone have experience growing this strain? Any tips? Should LST etc? Would a stout Indica benefit from topping or would I be delaying them for no reason? 5th set of leaves starting so I best figure this out ASAP

strain unfamiliar to me that said, i topped my grapefruit auto at day 15 lst'd at day 21. As for variety, genetic expression root obstacles (clumps in one container vs non clumping/ compacted soil etc lot of potential reasons.
Here is grapefruit auto about 5 days ago after readjusting the restraints and clipping just a few fan leaves off that were shading center growth. As of this morning stretch is on yet nodal distance is quite minimum about 3/4 inch w 6 main tops 4 smaller tops.

Nice looking sites from the top view on your grapefruit . I didn’t tip mine but have started a slight LST bending and trying to tick a few leaves. They are so short and bushy. Day 17.

I harvested one about a month ago. Very Indica leaning. Produced 3 ounces of nice dried nugs. Its sister is still growing. At 119 days today from sprout and over 4 feet tall, this one is very Sativa and huge. The pistils are just starting to brown and tuck in. Hoping to take it down in a week or so but we'll see. The biggest indoor plant I've grown. Photoperiod or otherwise. It is so tied up I can't even take it out for a photo
