Any suggestions…
And is it supposed to grow in height at 6.5 weeks into flower? Cause looks like she is still growing maybe cause got stunned at first week of flower?

Pictures in natural light would help and what was the ph?

somewhere around 5 ph tried to flush it and looked like alot of nuts came out, something like 4l off the runoff water was 5 ph
look at the photo of the leaf it is in natural light.

That is your problem. Your ph should be 6.4 - 6.6.

yes i understand that but what can cause the ph to lower so much to 5 ph on the runoff water so fast nut lockout in the soil?

I’m not sure. FFOF comes ph’d between 5.5-5.8. I used the same soil and ph’d my water to 6.5 and didn’t have any problems. The run off ph came up gradually.
