Nute lockout?

thanks for the idea's all but at this stage i think rez water temps could be an issue (its very cold here and water is a bit cooler when changed) I will grab a heater and preheat and see if helps, seems to have responded well to nute change (professors nutes) maybe i need to look at how i mix the green planet nutes, could just be this 1 plant being a pain, as i have 2 others on green planet nutes (at 3 weeks old) and they seem to be going great. cheers all will keep plugging on.

I can see you've had a few issues with this one but she's looking super healthy now! You've just entered flower so here comes the stretching, she's going to be quite a big girl in there a scrognet might not be a bad idea. Keep eye on your ph and ppm! 👍🌱

Hey, plants dont look to bad, hats off to you massive bloom formulation. I need to know your ec. your supplying if you already switched to flower nutes. I would start at 1.2 ec. I use to run rdwc with great results, I just didn't like how much the great big buds shrunk up when dried, so I went back to ultramix hp, as my medium. The main thing is to keep your water cool, freezer packs or frozen water bottles. Keeps slime from starting in between rez changes. I ran a chiller to keep the water cool. Not sure what temp is optimal, I forget but that info is out there. That's the main thing that will keep your roots healthy, no need for any root crap if your water is the proper temp. I went through a lot of different nutes for rdwc but the only one I liked and never had any issues with was DNF. Watered down crap like the rest of them but you get a huge jug of A and B for 100 buck. It's clear nutes so helps keep your rez clean. CHEERS.
