Any ideas what's wrong? Help needed.

Hi, I've attached pictures of my girls. They are looking really healthy apart from a strange withering/curling of some of the new growth.

They are in the 2nd week of flower in a current culture rdwc set up.

Ec is at 0.9
Ph 5.7 to 6.3

Humidity 75%

Using RO water but changing to tap.

Any ideas on what I need to do will be very gratefully received.

Thanks in advance

As you say it is new growth so it is probably something that changed recently? you mention humidity but not temperature?

Toriab · Feb 10, 2019

Hi, temp is 16.8 lights off and fans are set to come on to cool at 25.

The only thing that has changed is that I have them a heavy trim 3 days before it started. Could it be stress?

No its not from trimming. I'm not a hydro grower so best to wait for one to come along.

Maybe temperature in the reservoir/rootzone?

Toriab · Feb 10, 2019

Thanks, I'm pleased to know it isn't from the trimming. It's my first grow so the trimming seemed quite harsh.

The temperature in the rootzone is a steady 18.

Hoping it's something that's either reversible or won't cause a long term problem.
