alright im using a ebb n grow system ( picture attached) I used about 60% hydroton and 40% coco. Im filling the reservoir with tap water about 25 gallons and mixing Pure blend pro for nutes. There is one pump at the bottom recirculating and an airstone. My problem is that i adjust the ph to about 5.5 and it raises to like 7.8-8.5 over 24 hours. I didn't wash the rocks b4 i used them but they should have balanced out by now since its like week 4 or 5. the leaves are starting to twist. some strains are not affected some are really bad. leaves are fully curling up from the edges. I believe its a ph problem also I notice last time I changed the tank that the water was very warm at the bottom and the nutes were settling pretty bad. the temp of the room gets up to 105 but stays around 95. I feed co2 also.
