Good luck, keep an eye how things develop. Also checked out your Grow product, so it only contains 1% N, 4% K, 0,3% Mg, 0,5% Sulfur. And the Canna CalMg, is 5% N, 5% Ca, 1,5% Mg. So you are getting plenty of extra N with the CalMg. And Grow has quite alot of potassium. You could drop the Grow...

With lower end of temperature range you might not be able utilize all of the 1000ppdf, not quite sure of the temperature plateus. The increased VPD either from extra temperature or lower humidity should always increase the transpiration and thus some Ca intake. But getting much out of range...

Ye, the mother plants condition has significant effect how the clones root. Nitrogen is one the things that might inhibit root growth. Also some the cuttings seemed a bit woody to me. Usually you get better rooting with new shoots that are more green than woody. Spraying with anything shouldn't...

The other option would be to decrease the humidity a bit to increase transpiration. You could even check the leaf temp difference if you decrease the humidity a little.

Yes, yours might be even milder deficiency than I had. Mine grew out of it fine too, bigger root system and some more calcium in relation to K probably did most of the lifting. People go pretty heavy with their pruning especialy in veg, from complete defoliation to lollipopping. As for the...

Yes, definatly looks like mild calcium deficiency. Not sure how those ferts come out as for K:Ca:Mg ratios. But I've had something very similar with my plants before. The plants were small with establishing roots and the lower leafs kept dropping looking just like yours. While otherwise the...

With different organics you get different release speeds, so that's the learning curve on those. I'm of little help with those, but shells/bones usually I'd say will decompose pretty slowly. Especially at the very top of the soil, grind them up to a dust and mix them in the top layer and there...

Yea, some extra info would be good. But I would second the calcium deficiency idea. Calcium deficiency tends to leave brown spots like that, progress down the leaf and all the way to middle. Potassium deficiency usually shows more on the leaf edges. At the very beginning it could look similar...

Yeah, alot of different quality products for different purposes atleast, I can definatly agree there. I'm not a chemist enough to start talking about the reactions and precipitations of those. But I've read through some stuff on it and used for few years without problems. Knock knock :) I was...

https://melspring.com/wp-content/uploads/2021/04/Melclorite-70-G.TDS_.EN_._.pdf I have this kind of Calcium Hypochlorite. I opted to the powder/granules instead of household bleaches, because of the price and powder/granules are convenient to storage and have good shelf life. I'm already using...

I think the chlorine dissipates in bubblers in like 3days, NFT's and just mixing water with pump might take few days longer. So if ya using as a precaution, you could just add some when changing the water. It's no problem if the chlorine runs out if there isn't a problem brewing in the water...

https://rollitup.org/t/make-2200-worth-of-clear-rez-for-4.423650/ I've been using Calcium Hypochlorite for a few years now, got mine from swimming pool supply store. 1kg powder was 20-30e if I remember correctly, should last me for years. 0.01g per 1liters comes out as 5ppm chlorine. If ya...

I don't know, took maybe 5min of work and could do way bigger batch with pretty much same effort. That would last me probably for the shelf life of it, like few years. I suppose companies are selling all kinds of root hormones (which are the same stuff that is in the willow water). And all sort...

Yeah, completely valid idea. I just often transfer my mother while decently small and take the necessary clones when the mother is sufficiently big, that often leaves small margin of error. Probably could do stuff differently as far as that is concerned. But also interested in the topic for...

Well, as long as it's not your barn :D https://www.canr.msu.edu/news/rooting_hormones_improve_uniformity_among_vegetative_cuttings?utm_source=chatgpt.com https://gpnmag.com/article/grower-101-rooting-hormones/...

Fishing for more experiences on using willow water. Had a bit trouble of cloning this one strain and haven't really wanted to pick up any commercial rooting product. Well came across the willow water and went down 20meters from the yard to pick some up and prepped it using both the boiling...

Yes, too much negative pressure. Either lower the exhaust fan speed or open up the intake holes more. Can't see if you have any intakes open on the bottom of the tent?

Can't say for sure either, but I'd double check for having Thrips like HydoDan suggested. Check under the leaves etc, should have some Thrip poop there if that is the case. Doesn't really match with calcium or magnesium deficiency to me. I've usually had more brown spots from calcium deficiency...

Haha, need to have a read on this :D Just had the image of me sitting in my elf hat at christmas, a fan blowing all my kief to the carpet. Jingle bells, jingle bells

Went and got myself a dry sifter, vibrating one. Qnubu Autosift Automatic Dry Sift Maker. Got it on decent price (350euros), it had metal screens, which I wanted, 140micron and 70microns. So did my first run with my last seasons trimmings and some fluffy buds. It took several runs with the...
