Indoor Not flowering

[SharpStoner]

Ok so I found some seeds and started to grow after maybe 3-4 weeks 1 plant started flowering and the second just show withe hairs on sides and stretching for 6 weeks.

growing is soil ph is 6.5 and I am using adv nuts for bloom and using RO water. 150w led 3500k HLG board.
i went from 18/6 to 12/12 but still not flowering. should i cut it and start over with new seends?

They look super healthy at least! So that's good! Yeah I'd say give it a couple more weeks, some plants occasionally have abnormally long veg periods.What strain is it?
