Hi all, I’m reasonably well knowledges in growing using Bubble Ponics, I’ve not really encountered this fan leaf yellowing so quickly before, so I’d appreciate if you could toss up some ideas.
Growing in Hydroton
Sativas ( gorilla glue)
1000w viperspectra LED (dimmable)
Using Emerald Harvest and have been happy with previous grows.
PPM at 650 is where it’s been happiest
Falling slowly over a week down to 590
Fluid level falling too
PH unstable to a certain degree rising from 5.6 to above 7 over 24 hrs
I’ve done reservoir changes every 10 days during the grow.
I’m using Cal-mag now for over the last two weeks and also upping the Nitrogen slowly whilst I monitor.
Roots are nice n white
I also add Some Great white Shark every res change ( great product too BTW)
However despite my methodical efforts, she continues to worsen.
All ideas welcomed.
