Bushy growth

Hey everyone. Started another grow and the plants are going on 3-4 weeks but I’m getting a lot of real short and bushy growth and barely any vertical. Just wondering if there’s anything I can do to increase the height. Light is 550W HLG LED and is about 24 in away from top of canopy. I know my soil PH was low in the 5s and I added even more dolomite the other day to correct it. I think that may have been the main issue but it will take time for the dolomite to break down and correct the soil PH

strains: peanut butter breath, tony greenhand random pack, and bagseed
soil: MG Natures Care potting soil w/ added perlite
Nutes: fox farm trio

lights: 600W HLG LEF, also a supplemental 50W blue LED.

Humidity 40-50%. I know it’s low for veg but my flower tent is in the same room and the exhaust is connected.

soil PH is 5.5-6.5 on some plants.

If you want it to grow more vertically just leave them be. Don’t do any training and they will grow vertically no problem. They’re still young too they got a lot of growing to do.
