[King Coala]

So the season is enough to a good start for me I hope everybody else is doing well. My beginning to the outdoor grow has been slowed down to a crawl and I think I'm losing a lot of my plants due to either I thought at first bugs and then I'm starting to believe that it might be fungus can anybody help me with this thank you in advance, King Cola Ottawa

Hey King Coala,

Welcome to 420! To help we need more info.... What’s in your soil mix? How old is the soil mix? How often do you water them? What are you feeding them? Did you make provisions for cal-mag either in your soil mix or in your feed solution?

Just by appearance and without knowing answers to above questions I would throw a dart at watering too frequently, not enough aeration, possible pest vectors and lastly perhaps it’s just rust which could be addressed with a bit of sulfur dust and BTW’s wettable sulfur is good stuff since it’s a miticide and helps prevent pm

drop some answers on us
