Please someone help me diagnose my plant problem. As you can see there are Brown Spots starting to take over my plant. My water is PH'd, temps are 78-81, added 2tsp of Micro & Grow last friday.
you're gonna need a bigger rez. each plant should have 5 gallons of space. you'll have a hard time keeping things in range if you don't. the ph will be all over the place.My ppm is 337 in a 10 gallon rubbermaid with 2 plants with 6 gallons of water
