Hi, I'm seeing some burn/orange spot, but mai...

i'm seeing two problems and it's not the feeding that's the problem. So basically you have 1. symptoms of pH fluctuations , if you have a continuous monitoring system you'll see that your nutrient solution is "breathing" fluctuating in pH and PPMs, if you dont then check like a different times of the day and you'll see that it's not stable. You need to stabilise the pH by adding more ph perfect grow juice. simple. Second problem is the start of a root problem , check your roots are they all completely white ? if not, then clip the brownish and goo-y ones . yes, cut off part of the root zone, dont do more than 20% total root zone, but try clipping the tips and some problem roots. you'll explossive growth within hours. To prevent root zone problems make sure you have a chelation agent in the mix or something like Hydroguard. Hope this helps ! 🚀
