You got any recommendations on one bud
I like the Bluelab brand ...however they can be pricey ...you can get a basic one on amazon for under 20bucks, just do a search for a tds/ec or ppm meter .. I also wouldn't feed them any nutrient solution ...give them straight water until you get a ppm/tds/ec pen and can test the toxicity of the run off. say that because if you have been feeding them from the beginning im certain you have build up as I do know that soil does not flush salts out like coco ...so it may take awhile ..
