Well my blueberry seedlings were doing fine until I decided to add some techniflora Root66 to the soil thinking it would makes the roots grow faster. My PPM was 200. Now on 3 of the 8, it looks like the tips of the two leaves are turning brownish yellow. I don't want to flush them because they are so small and don't want to drown them. Sorry no pics, I am at work at the moment. Shouldn't they be ok it I just give them Plain PH'ed water for the next couple weeks and give them some nutes when they are bigger? Thanks
