Premature flower from light spectrum change

I have made another rookie mistake. I got some more t5 lights and moved some of my mothers from 400watt HPS to the T5s. Now they have started to flower. No light schedule change. Just different type of light. I understand what I did wrong, but am a little confused on my next step. Option A: Change them back to HPS with a 12/12 schedule and except the genetic loss (no clones yet). Option B: Leave them under the T5 on a 18/6 and hope they go back to veg? Basically I dont know what to do.

Often strains do pre flower any way, you are wrong about the lights more an environment thing than light, leave them bee, they should re veg on 18/6

Getting used to being wrong. Thank you for the advice.
