IR ,

I think its a real bonus being able to get advice from the seed breeder as you grow their products.
I think you're probably right about the fungas. I thought it might be soil related and switched from Shultz to Promix. But the one plant in Shultz(with extra peat moss ) is doing ok .
I suspect I nute burnt some plants.One has a few leaves with yellow spots going brown and one has some bottom leaves going pale yellow.
I read that worm castings couldn't burn the plants.
I will soon be transplanting to bigger pots from cut off 2 l soda bottles. I plan to use promix mixed with some worm castings.
It looks as if the 3 plants I have will be females. I suppose I'll be happy enough with my small closet grow even with my fungal losses. I really don't have the room for more than 4 plants. I don't want to have any disasters now as I'd like to harvest a crop by May so I can have some campfire smokes while camping.
