My plants keep melting and turning brown. I feed sechem flourish liquid and root tabs but no luck. My plants did awesome, grew wonderfully and bright green in my 10g with 6500k plant lights...I moved them to my 20g long with the a 6500k light but it didnt look as bright as my 10 gal, thats why im thinking perhaps its a light issue.
Should I upgrade my bulb or go low-tech...
If I go low-tech I need some good ideas for really hardy low tech plants
If I upgrade my bulb (if you think thats the problem) what k rating should I try this time?
