What is the strain and what is your pH? Looking like the beginnings of a pH issue to me.

Peace.

The strain is CoC Amphetamine Automatic and my ph is staying stable around 5.6-5.8

Distilled

Are u useing cal mag

 

[mr sweets]

If you are using distilled water you have to use CalMag in your solution of your nutes I have the same problem the first 3 weeks I did not use CalMag and I developed a Cal Mag deficiency in my plants when using distilled water for reverse osmosis I learned that you have to use that this is also my first grow so I am by no means an expert I am just going by my experience so far what nutes are you using

 

[1highman]

No but I have ordered some this morning.

 

[mr sweets]

That was my problem after starting to use that all my problems went away

Updated problems, Calmag should be here in a day, 2 at the latest. This is what they look like today, plus I checked their roots and the roots are brown, not slimey just brown. Water temps never got above 70f.
