Bud sites small but clone keeps growing

My clones are 8 weeks old , cloned from mum when she just started to flower.
I run 12 /12 lights LED blurple light yeah yeah I know sue me cause it blurple but it was free

pH sways from 5.8 to 6.2 depending on water and nutes.
Temps run from 76 to 86 F measured at the base of the plant.
Humidity ranges from 45 to 60 %.
Its growing but the bud sites don't get bigger?
Seems its stuck in stretch mode with dash of flower LOL

Hormonal disarray caused by too many nodes too close together, all fighting for dominance in an open field.
You need to clip off every other node, starting with the one below the top shoot. Watch carefully for a few days, as the top may continue to spit close nodes, trim those as they appear.
This is a common occurrence with "slow" clones, and it's best to watch and stay ahead of the condition. Generally, the plant will outgrow this phase, but will lack structure and vigor in the long run, so surgery is the best course of action.

Thanks for the info, I will be snipping tonight..
