Hey folks. I'm taking my first crack at ebb and flow using rockwool and hydroton. I made the mistake of not feeding often enough and now have deficiencies. My question is how often can I feed to correct this problem? I was feeding twice a day when the problems arose(in veg, lights on 24 hours), so should I up it to 4 times a day? More than 4? My nute strength is around 700-800 ppm, PH at 5.8-6.0 and water temp around 70 degrees. Thanks folks.
