3 problems: broad mites, germination/propagation and stunted growth (? possibly).
Hi all,
As the title say I've got three problems/questions,
1) Broad mites on a seedling (growing its second pair of leaf only and one of them is twisted, also noticed the edges of the leafs pointing up, in a weird way.)
2) Out of 8 seeds, 2 didn't sprout, 1 is looking really F* up. (considering the price, bought from trusted seed banks, I'd wager I did something wrong and I'd like to understand)
3) My first auto-flower is on her 23rd day, and is looking very small. I wonder if its normal, or if I did something wrong.
I grow outdoor, in a makeshift greenhouse, already amended the soil, germinated my seedlings inside and let them sit in the greenhouse during the day, til end of April frost is to be expected so I cannot plant them til then. Didn't expect this, germinated them somewhat a bit early, so had to swap pots for three of them. This is my first time grow. I've read carefully every single piece I could find online, now mostly rehashing information I already read.
Thank you for your help in advance!
1) Broad mites??
So as I said, I believe these symptoms are broad mites, but I do not have any magnifying glass of any sort yet to make sure -ordered a phone "clip-on" microscope, thought i'd try it, if it works take pictures of trichomes. Will arrive in a month only- The leaf edges are really curled up, maybe we cannot see properly on the picture. It makes me think of pimple, a bit gross I admit. Since its a seedling, I guess the "plastic" effect is not yet shown, infestation is still low. (remember this is my first grow, and I'm guessing most of these from information I read) What do you think?
I also noticed on this one and other plants small tiny web, from the cotyledon to a leaf, like a spider passed on it. That's also something that makes me think of broad mites, or spider mites, but this is the only plant to display such symptoms. I've quarantined it (washing my hands after touching its pot should be enough? and also not in the same room, obviously. Trying to avoid any contact between the cats and the plants also)
Today I went to a big gardening center -if i cannot find what I seek there, I will not find it anywhere else (easily)- bought three different type of defense/attack vs mites: colza/rapeseed oil (couldnt find neem oil), oil made from vaseline (suffocating the insects, I could post more detail on the exact composition if needed, something that ends in "im"), and finally powder of diatom (supposed to attack the insect but not harm the plants or the cats). Is this good enough?
Can I treat the seedling with this?
Should i treat the others "just in case" -because I saw web-?
2) Germination/propagation problem
That's a feminised seed, should I throw it? 2 seeds out of 8 didn't sprout, and this one look very weak. I believe I kept them too close to the heater. Also their soil mix was never drying (humid and hot, perfect for fungus I reckon!) So I came to believe these three were afflicted of some kind of rot. (Weirdly, two other seed did very well on the heater, leading me to think these two seeds love hot conditions, compared to the others who did poorly). (9 seeds = approx. 50 bucks, you can understand why 2 seeds out of 8 is worrying. Especially considering the stunted growth of the other and the mites on another one)
I've already decided to replace this stunted seedling, its replacement is germinating right now. I was thinking of keeping it in a pot, instead of planting it. But maybe its not worth the trouble, what do you think?
3) Stunted growth or normal?
Is this size normal for an auto-flower at 23 days of life? If not, is it because it doesn't have enough sun?
Also, notice the light color of the "backbone" of the leafs. Its not very visible on the picture, but it worries me a little. As if it needed nitrogen, (I dont think so though) or that it was root cramped -it is not-. Young leafs are lighter in colour, I know and expected it. But it seems the second pair (the one pointing north and south on the pic) gradually become more white. Its only the "backbone" -im not sure how to call that?- that's touched. In between, it stays green. Is it normal, or something else I have no clue about?
Once again thank you for the help, I don't expect a huge chapter as a reply, I wrote so much only because I needed to explain the problems. (First grower, pardon me, getting hyped about everything, even though i was warned not to "over analyze"
)

By making the mistake... it seemed fine, summer was coming, but I was wrong.
