Nutrient lock?

@Eponymus29 the way those leaves are drooping and lacking vibrancy I suspect you may have over done it with the hydration in future allow some drying out between feeding/watering which will allow your roots access to oxygen which is integral to happy plants

I’d be suspicious of that pH my friend.. 5.6 is low even if you were in straight up soilless. If its soil look to be mid 6-6.8. If it’s soilless (peat / coco) I’d shoot for around 5.8-6.2 during flower.. They also look a bit hungry.. I’m not familiar with what you’re feeding so I can’t comment on that but they’re going to stretch and whatnot soon and need a lot of nutrients available so I’d keep an eye on any deficiency symptoms Good luck

This is going to nutrient lockout but because your ph is off I read your diary and for the most part you kept your ph between 6-6.3 which is fine but once it went under 6.0 I'm sure you started noticing some problems. I like to keep my ph between 6-6.5 which is recommend for growing in soil. Next time you water check the ph of your run-off to see how low it is so you know where you need to raise it to.

Looks half soil and half soilless. I would shoot for a ph of 6.1 to 6.3 to compromise.

If this is a soil grow, then your ph is set low. Closer to 6.5 is good for soil.
