G,day all. I recently purchased a brick of coco,i soaked it in ph 6.0 water 3 times added some dolomite lime, potted it up let it sit for a couple of weeks. next i started some seeds in jiffy pots and planted into pots when ready. Plants have been going well for the past 2 weeks. There does not seem to be any problems with them, they look a little light in color so added a little fertilizer to their water this morning ph,d to 6.0.This is the first full watering of the pots for a 10% runoff.I was surprised to see the runoff water a dark brown,when i tested it the ph was 7.5. Where have i gone wrong and how do i fix it? I believe this is the tannin still coming out of the coco.? Will this cause any further problems ? Should i flush the pots until the runoff becomes clear ? Any advice would be most welcome.
