this is my fourth time growing. i always do 4 PF cakes, and never had a problem until the last (3rd) batch.
i had 3 successful flushes (with 10:1 water:h2o2 dunks in between flushes) and after the third flush, got a nasty green veiny mold that initially looked like bruising. i picked what i could and pitched the rest, chalking it up to spent cakes and cold weather outside.
in between growing times, i clean out my aquarium using lysol and h2o2, rinse and dry it out and store it. during fruiting i use perlite with a 10:1 water:h202 solution for humidity. i seal the top up with vasoline and saran wrap. i air 3 times a day. i have lots of condensation in the tank, so i'm pretty sure humidity isn't a problem...and like i said, the first two batches i did came out great...
anyway, this time, i have 4 fully colonized pf jars, nice and white and growing strong. the first one pinned, so i birthed and dunked it. put it in the humidified terrarium, within a few hours the bruising had subsided and i notice the green veins starting to pop up. i'm positive that it's the damn mold.
there's an almost orange undertone to the mycellium with the greenish veins underneath, the cake also seems unusually dry for just being dunked. it's almost like the cake is totally spent and i JUST birthed it!!! and if history is any indicator, within a few days, the mold will completely consume the mycellium and the cake. i'm SO frustrated. does anyone have any advice on how i can kick this stupid mold? i still have 3 cakes in the jars, so luckily i haven't lost the bulk of my harvest, but i'm PISSED.
If it is some kind of mold, then there's nothing you can do save those but are you sure that isn't bruising ? The pics are a bit blurred but i think it could be bruising. Hardly a contam can come that strong in such a few time.... Also, have you changed the brand of the BRF you're using ? Sometimes the formula has to be adapted to a specific kind of floor, failing to do so might produce a substrate too dry or too wet. Mycelium looks weak if grown in a dry and packed substrate.
