Hello RIU
I have been budding this GDP plant for about a couple weeks, i have not bought a microscope to check combs, but i am a couple weeks away from chopping her down any opinions ?
None of the hairs have changed color at all. And if its only been flowering a couple weeks then i would at least wait another 5 weeks. Patience is by far the hardest thing growing the ganja. Plant looks real nasty though! KEEP UP THE GOOD WORK!
Um no products will be helpful in that department IMO
I've read that you could try decreasing the temp in your grow area more during the dark periods, this encourages certain strains to take on blue or purple colors
