NO GOOD. so i flushed her today hoping that may clear her up.i dunno though. cant post pics so i hope i have givin enough, p.s the buds look good and are growong fast but some of the leaves look just yellow and bad. what should i do ?!
Don't use tin foil.....either put mylar on the walls of the inside of the PC or paint it flat white... and 87 degrees if a little too hot in my opinion...I try not to let temps go past 82 or 83.. No less than 68.. I agree with pictures.
like omdogg said switch out the tin foil for mylar or flat white paint. Tin foil can lead to hot spots and when the surface gets wrinkled it not as efficient at reflecting light.
