If your run off is higher than the in, it suggests your plant is not taking as much nutes as your giving it, this can also cause nutrient Lockout.... Just flush her through and dial back the ppm

I think the plant eats enough because it has a huge root system. i used at first in rootbastic atami's. I'll wait another two days to see if the calmag works, If necessary, increase the dose

Burnt edges / yellowing What are all these burnt edges from? One of the burnt leaves is from the perimeter, so I'm not sure how it could be receiving enough light to burn. I also have a small amount of yellowing towards the bottom. That's normal during flowering if the low-light leaves die, right? Thx

Would greatly appreciate any feedback on improvements, those 2-3 leaves with yellow spots seem concerning. On 'honest' scale of 1 to 10, how are my buds looking for week 6 in flowering?

EC too high and leaf yellow EC 1.45 and some yellow leaf… I adjusted the soup by adding water to it and the new leaves seem to be pretty ok. Otherwise, all other parameters are good. It’s odd bc I followed instructions of the brand (Platinium Hydroponics) and the EC lvl is still kinda high. Suggestions?
