It was a busy week and i was careless with ventilation. When i discovered rotten spots, four buds where already infected. Three on the left and one on the right plant. I cut off the colas below the rot, did some defoliation and corrected humidity and ventilation. I hope it won't spread again for the last 1-2 weeks for ripening.
i know its 3 years ago but how did you like the migro light? i just bought the ARAY 4 for a 120cm x 60cm tent and would like some input or maxbe a tip (:
