I have already mixed my soil and put it into pots, the seeds are on their way and I'm hoping to germinate them next week. My mix consists of 40% general potting mix soil, 40% coco coir and 20% perlite. Using GH Flora trio for nutes.
Testing my soil/coco mix ph gives me a reading of 5 (even after flushing it with ph 8 tap water), which is way too low for soil so i purchased some fine dolomite lime and I'm going to be mixing this in to my soil prior to planting the seeds to neutralise my mediums ph to 7. My plan is to then ph my feed/water solution to around 6-6.5 in an attempt to cater for the coco as well as the soil, hoping for my run-off to be around ph 6-6.5.
Is a ph of 7 too high for coco? Will it have any drastic effects or will it be fine.
Sorry if this is a dumb question, i wish i had just soil or just coco but its too late now and i want to try get the most out of my current soil/coco mix.
Thanks in advance!
