I was thinking of switching to clay pebbles tomorrow but wasn't sure now I will definitely be doing that in the morning.
no you can't go to clay you don't run flood i mean you can run drip but it has the possibility of not dripping to all the areas needed... a
you need to really simplify what your doing. first off take the rock wool and remove any excess the plan hasn't grown into.. take the plant and plant it into promix.. sunshine mix 4 or coca ... id suggest promix.. its ph neutral and at its dry state can rebalance your ph if you really fuck up your ph on watering or something.. but you need to get it out of the rock wool into a potting mix.
how exactly is your drip setup? there should be a reservoir.. with a fish tank pump pumping air and a water pump circulating the water in the reservoir keeping it mixed properly.. that reservoir needs to be ph balanced also... so how are you ph balancing the reservoir? also the resivor has ZERO excess waste water flowing back into it correct? all your waste from the fresh nutrient drip system should be going to a waste bucket or something and not back into the reservoir.... do you have it setup that way or are u reusing waste water from your plants too?
