Humidity problem with rockwool blocks in sealed environment?

I switched to external air without the supplemental CO2. Unfortunately some complication occured.

Not able to see your plants, I’d try to maybe give them a spray with humic acid which should help with nutrient uptake and increase humidity a few hrs before lights on!

It is somewhat normal to see a nitrogen shortage in the stretch period but at 5 days shouldn’t be that noticeable yet , maybe the huge difference from where they were to now is what your seeing ie tropical jungle to desert!

I’m leaning towards nutrient solution and/or ph out of whack.
