Blue Ice OG - LowTemps = Color Change
Trainstarted grow question 4 years ago
I am currently growing Blue Ice OG from seedsman.
Seedsman advertises that this strain can develop shades of dark blue and purple colors if it is exposed to nights below 12°C(54°F).
My question is, when during the grow cycle would you do this?

Let temps drop near end of flower so as not to impact yield much. You shouldn't need to drop into 50s. low to mid 60F will likely have the effect too.
It doesn't take much time. trial and error needed, but i bet you see a color change after 1-2 nights.. at least hints. do it as long as you feel necessary. This likely impacts photosynthesise... it's not a wise thing to do, imho. cold nights are not optimal for plant biology, which is tied to why colors change.. .again, not optimal to cause this to happen.
So, i'd start later in flower... and rest assured it won't take more than a week or two to get a good autumn look going.

Most strains will exhibit blue/purple tones if exposed to cold nights for a period of time.
If controlled and to avoid stunting, you may want to begin in week 4/5 of flowering.
If the strain naturally develops these tones as part of their genetic makeup, there is little that needs to be changed for the change to occur.

By the timing In the wild I mean that it would naturally get the coldest at night during the Last few weeks of flowering, hence this is most likely when you should drop down the night time temps to push her colours out. Theoretically....

Then it's a question of where does this plant hail from. I'm from Missouri a zone 6 grow area. Our temps normally hit that low at night around December.

I believe you would do this when it would naturally occur in the wild, late into flowering.

Bract/calyx turning brownHey fellow growmies,
i noticed brown bract/calyxes on one of my plants. (week 12, auto, 20 % amber)
Iwasnt't worried until I found them inside of some buds while checking for budrot.
Should I be concernend (cut the buds), or is this just the circle of the plant life or genetics?

Edible out of fresh harvestHi, I'm not very much into smoking weed, more like eating edibles. In cause of financial and space problems, my plan is to make edibles stait out of the harvest or after the drying. My question is: Does the curing/fermentation effects the potency or effect of the weed?Buds. Other

Too many colas? (Serious)I'm scared that I have too many colas. I have to continuously trim leaves to avoid humidity hotspots. The internodal distance is super short. All branches are stripped from all leaves except the ones visible from above (3-4). I am afraid that the buds won't have enough space

Small holes, yellow border, new young leaves, Fungi?What could this be, and how can I treat it?
Been very Humid the past 3 Weeks. Rainfall increased too in South Germany.
Treated it with Neem Oel. I think/hope it stopped spreading. Been observing it for a week now and always treating it with a very thin mixture of Neem Oel.
