Hey there jeanpol so regarding the high cbd strains, from friends who've grown them they continually told me that their cbd strains had to be harvested earlier than their high thc sisters . I believe this is because the more you let them go the higher their thc levels can get. Id say just give it time and try to harvest them when the majority of their pistils have slowed growth, discolored and curled inwards. If you can watch for more milky trichromes do, but you may not get to the typical vision of a low cbd strain(milky/amber). With your recent rains etc can they be moved inside at night? This may help slightly at least to avoid pooling of water droplets that are a mildew/mold/fungus dream home.
Happy harvesting ✌️
