First White Widow Grow

I have heard mixed reviews on that brand, I don't think I would use them. But with any company that is a reseller of products they do not breed it is going to be a real hit and miss. Most companies are resellers and not true breeders. Some of them work with the breeders of their prodicts and make some good things. Others get lucky and have a few strains that really kick ass. Check out Ethos seeds or Barneys farm Good Luck!

Thanks guys for the feedback, but I have added a second fan, and I don't have much drop. I've set my light as high as it can possibly go with fan a couple of millimeters (sorry to my American growers) to give it enough room to swivel without touching the light and get it as high as possible above the canopy. Struggling!

Your plant is fine. Growth should show down soon. There's not much more you can do but lightly bend over nodes if you have to but it should be fine. As for wanting to be in 50-60%RH I have no idea why you want that during flowering. Those are veg ranges. Pre flower 45-60max and start bringing it down as close to 35 the closer you get to harvest. Good luck.

Looking at your plant it looks fine. I wouldn't remove anymore leaves for a while, you have plenty of air flow around and through the plants as it is so you won't need to worry to much about the high RH. lower the humidity in the room your tent is in will then lower the Humidity of the tent. It should be at the end of its stretch so it won't get much taller, if your concerned some of the colas may be to close to the light you can bend them 90 deg.

Powdery mildew is the result of growing where the spores are AND having far too much humidity.... If you can't get your humidity down (55% is high), you are also risking bud rot along with the PM... Your grow looks, on the surface, to be pretty close to being ready to harvest if not harvestable right now (we'd need to look closely at the trichomes to be certain) - but, if this were MY grow and I was facing these issues, I'd chop.... If you chop when the trichs are milky (and I'm willing to bet they are from the look of the pistils), you'll get more of a cerebral effect from your smoke rather than a relaxing body buzz (if you wait until some trichs are amber) or couch lock (if they're mostly amber)... So your call.... Good luck! p.s... and when you're done with the tent and they're all harvested, scrub it out completely and thoroughly with a mild bleach solution as you don't want ANY powdery mildew spores to infect your NEXT grow!)
