Looked like I was getting some nute burn so diluted the existing res by 1/2 last week and went with half strength this week.
HBSS looking like it might have a nutrient issue of some sort. Will give it a couple of days and see how it evolves.
I think itโs ph fluctuations causing problems. Not affecting the SODK, but the HBSS is hating it!
Have decided to be a bit more strict with my ph. Moving to 6.2 this feed and to 5.8 next feed. Then keeping it there
