flush, and switch miracle grow with a recommended nute, that stuff supposivly is horrible for pot
 
all good spot spot prob rubs off and buy advanced nutrients and use 300 ppm till a foot tall then to 600 ppm till 2 feet then 800 ppm till 4th week into bud then 1200 ppm till wekk 6 then flush for 2 weeks
 
alright guys i cleaned and flushed the res and the plant looks better.

the plant that was bent over died so i only have 1 plant left good thing its just some bag seed:)



also. is it alright for me to keep my plant with the reflective disc thingy over it, or should i just leave it off.

i read somewhere that it was good to cover your plants to stop the light getting into the res causing algae
