I have yellowing and curling of the leaves and wondering if this is Nitrogen def? I’m running DWC and using Humboldt’s Secret, but we have stunted growth with this girl. It’s critical mass from Homegrown Cannabis CO.
We are thinking It maybe root rot, because we’ve been dialing up the nutes for weeks and she’s been struggling. Below is my growlog. I will include a pic of the roots later. They are naturally dark from using HSS golden tree
Oh yeah and I already viewed them! Sorry I’m replying do multiple posts at once 
@Shadowfly325
It’s definitely starving for some nitrogen, I’ve never ran a dwc grow but there are many folks here that do. How much nutrients (strength) do you feed it? @Shadowfly325
i’m over half strength now ppm reading 776 minus 150 or so ppm ( hardwater)…we’ve been increasing for a few weeks and it hasn’t changed. However, the roots aren’t as big as her sister cousin and they are looking xtra dark. Stunted growth too! ughhhh i’m hoping to save her
Hey @SLIMER75 you grow with dwc right? It’s definitely nitrogen deficient but I’m way too rookie to dwc growing . What do you think? @Shadowfly325 can you add some photos?
photos are in the grow log. i eill add some of the roots
@Shadowfly325 I have seen this before. I would suggest putting some Hydrogen Peroxide in the water on the next feeding. I had to get the strong stuff from my local grow store. If you try and use the stuff from you local box store you will need a ton of it.
