Over watering symptom?

Hey people,

I have some plants which are showing some alarming signs and would appreciate a little advice.

The plants are in coco under 300w LED and temps are 26-27C. They are being fed with canna coco A+B and I have foliar fed with rhizotonic and some cal mag.

They have recently been potted up from 2 litres to 12 litres and are getting a light feed until run off every day. Humidity is quite high at 70%.

Im thinking it could be overwatering as they have gone into larger pots but I thought putting more water would draw oxygen in the pot? These are fabric pots and there is 30% perlite.

Any input on what it could be would be appreciated alot as I would like these plants to be healthy to clone from.

Thanks!

Still looks like it could use some calcium. Got your ph right?

Drop your humidity. Your plants look like they're having a difficult time with transpiration.

OK thanks guys.

My Ph has been 6.0 yesterday 5.9 and I add a small dose of cal mag each watering so my water starts at 0.4 ec.

Humidity has been a problem ill try and drop it to around 60% and see if they are happier and report back.
