I changed the way to cool my water temp because running your nutes through the waterchiller will cause problems with it, because i see it get clogged up with nutrients that fall out of solution, which prob have been one of my biggest problems.
So I now installed a coil attached to the chiller which will indirectly cool the nutrients, just by placing a colder element into the reservoir.
Right after i stopped the chiller and added a bit calcium my ph went stable again.
This dwc has been a pain in the ass since i started this, but very valuable lessons learned on the way!!
I noticed my plants aren't dying of stress or anything anymore so thankfully the last couple of weeks been alright and things look pretty good today and they still need 2 weeks to finish, so hopefully they fatten up a bit more..
Cya next week!
