i av 2 WWs from GHS and one of them is showing similar traits as urs on bottom leaves they av only been vegging for 4 weeks so cant tell u how things pan out but i am growin in soil with 1200 watt hps, PH 6.5, i also av other plants ( 2 cheese ) and they show no signs of bad health so far touch wood ! i only noticed it the other day not quite as bad as urs but deffo the same looking thing, so am concluding its in the plants traits to do such thing ( possibly ) as were both doin completly diferent methods from medium to light so we can rule that out i think based on the fact we both av other plants showing no such signs, last time i bought from GHS they hermied on me more my fault bein a nooby but i hope there not just gonna bring me bad look again as a lot of peeps dont recomend GHS but the WWs i grew was trippy high weed one of the best i ever smoked even though i ended up havin a load of seeds i did not want ! so after doin a couple of grows with other seeds supliers i thought i wud give GHS a final try of the widows, mine r roughly 12 inches high n will b flipped to 12/12 in a week or so !!!!!!!!!!! fingers crossed for the widows, lol !
