this is my first grow! im using an unknown strain as a trial run before i start growing some barney's LSD! so my grow has been going realy well, the plant has been looking very healthy untill about a week ago. the leaves at the bottom of the plant started to develope a yellowish tinge and there are there are deformities around the edge of the leaves that look like burns. i re-potted the plant, have given it a flush and watered down the nutes and it started to look more healthy, but in the last couple of days the symptoms have spread to the next set of leaves up! can anyone help? i have no idea what the problem could be! here are some pictures if they help. cheers for looking everyone, Shibby!
