You’re getting a touch of nute burn there buddy. Do you know your runoff numbers ?
100%. Minor nute burn.
Runoff numbers? Sorry don’t understand my friend… they ar on veg day 40. Biobizz soil light mix. Water them twice with nuts and 3rd without.ph 6.5 biobizz nutrients.
Not sure how effective nutting on plants will be but give it a shot. Pun intended.
Runoff is the water coming out of bottom of pot when you water. You can also do a slurry test which is more accurate IMHO.
Runoff is the little water that collects in the tray after you water your plants. I collect it and test using a pH meter and an ec meter. That gives me an idea of how the soil is doing. The value is PPM and it has a figure that your soil should be at during each phase of your grow 
Thank you very much bro:+1:
