This week I gave the #SpaceCookies a flush of aired tap water. Comes out of my tap at 330ppm, which is very high, so I bought a water filter.
I bought the wrong filter though, so we're using that one as drinking water and I'll save up for a reverse-osmosis water filter - doh.
Girls I think are looking a little ragged in the old fan leave area, so perhaps light burn, nute burn, heat or the spider mites are back.
End this week and I'll think about defoliating a bit. I have taken the odd leaf of here and there, and this week I removed a handful of the oldest and worst looking fan leaves.
Buds are changing from torpedoes into rockets by filling out a little. I have 5 plants, a couple are quite short and busy, a couple are thin and tall, and one is busy and tall. The latter is the one I took a clone from, that clone (SC1C1) is itself in flower (day 4) and there is a clone (SC1C1C1) that seems to be rooting. #ShaggyGrower @ShaggyGrower
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 itโs not a mobile nutrient as the leaves grow your requirements of calcium or not met hence the spots. Now that youโre adding โcal magโ you shouldnโt have anymore issues. (Calcium is required at 6% magnesium 2% each feed) hope that clears it up for you ;)
I've been umming and aahring about who to give the Select As Answer to as they're all very similar and helped to a similar degree. They all got a Like for that. Winner is (please don't get disappointed others): ExperimentGREEN.
@Kushlove420, had to feel what it was like to be infested by spider mites then work through it. Diamatacious earth sorted it (third attempt after neem failed, predators failed, and pyrethrum failed)
@biggreens420, Thanks. Yes, filling out nicely. There's showing a little nute & light burn, and they've had a spider mite infestation to deal with (with Pyrethrum EC5 tried first, then predator mites). They seem to carry on regardless though. Day 33 of 63-65 today, so still a white to go and I'm wondering just how chunky these will get by then. I shall have to wait and see :)
Hi @ShaggyGrower, this definitely looks like a Cal/Mag deficiency. I see you already gave her some TNC CalMag, so we'll know very soon! Happy growing ๐
Those pesky spider mites they really are a pain, i feel for you because I had the same problem this grow!
Anyhow they always turn yellow around the 17th week of flowering, they are reaching the end of their cycle and soon will die...
Now they are not pushing flowers but the buds are going to swell and bulk up, so as long you still have 60 to 50% healthy leaves you are good...
