The Space Cookies are creating pistil sites & buds at a lovely rate. Perhaps this has occurred as I have done hardly any defoliation this grow compared to normal.
This means the plant(s) will have been less stressed, so maybe that's why they have amazing long colas forming, like torpedo's. In the next few weeks I hope they will thicken up
as the calyx creation Fibonacci's. Gave some Shogun Geisha Foliar to create even more bud sites. Fed with some Shogun, and this is on top of the Greenhouse Feeding
already in the media. They have taken a lot of nutrients VERY well. I have let them get very dry between watering's, and the Shogun CalMag seems to have halted the
brown spots on the leaves.
What effect does heat/cold have on roots & above ground? So, what effect should I see in the roots and above ground growth with substrate temps at 90f, 85f, 80f, 75f, 70f, 65f, 60f, 55f, 50f, 45f, 40f?
Hey there so extreme cold will slow your plant growth ans can eventually kill the plant especially at freezing temps. I see the plants are partly outdoors partying with the tomatoes which lucky are much like cannabis, at this stage if you can keep temps between 70-85 with good humidity thats best, but even if you went down into the higher 60s that's ok too, with slightly cooler night temps. If your substrate can stay above 60 it'll discourage mold and other things. The plants and tomatoes are looking good. :) oh also a lot of your plants leaves look like they're "praying" which is a good thing. I think things are coming along great.
Have a look the leaf photo's in Week 12 and tell me what excess/deficiency you see. I think it is a Magnesium deficiency but I'm far from sure. The leaves effected are mainly middle of the plant fan leaves or lower fan leaves on the cola's.
Hi Shaggy. Looks like textbook calcium deficiency. Magnesium looks interveinal chlososis, calcium shows up as brown spots on leaves affected. The requirement and deficieny signs with calcium can be weeks apart meaning your middle leaves needed calcium 2 weeks ago and because it’s not a mobile nutrient as the leaves grow your requirements of calcium or not met hence the spots. Now that you’re adding “cal mag” you shouldn’t have anymore issues. (Calcium is required at 6% magnesium 2% each feed) hope that clears it up for you ;)
