the picture thing is being weird and not letting me upload right now ... but i was reading and checking around and it said it is prob the early signs of nute problems and i should flush the pots with 9 gal of water each... but i dont have the soil all the way to the top , only like 3/4 full , and the rest of the plants seem really healthy so i dont know if its such a good idea to flush them... can anyone give me any advice on this ? greatly appreciated if you could...
