Hi all,
An absolutely beginner here… I bought a couple of autoflower seeds and germinated them to see if a simple window-sill set up might be feasible.
After geminating in paper towel, I started this Wedding Glue autoflower in store-bought flower soil (ach, I know… now!). Two days ago I transplanted it to a larger pot, and added Plagron Grow Mix (100% Terra).
While the plant seems really small and thin (it’s 9 weeks old…), owing I suppose to the relative lack of direct sunlight (I am doing the best for her I can, but I’m not set up to do this -for real-), it has looked otherwise healthy (to my untutored eye anyway).
Until now. These spots appeared within the last 24 hours, and at time of writing seem to affect mainly the mature fan leaves; the newer growth at top are presently not affected.
I’m using Royal Queen Easy Grow as nutrients. I don’t have PH testing kit or the like. I read somewhere it might be calcium deficiency? (The place I read this didn’t say how to fix it, if fixing is even possible).
Thanks for any help or advice!
I suspect a pest of some sort. If you have a magnifier you can look at the underside of the leaves and maybe spot the critters.
And you are correct, window light is not enough to grow a good cannabis plant.
Any chance of taking it outside to get full sun?
Thanks, Spiney_norman. I’ve had as close a look as I’m able and don’t see anything… aside from little pieces of substrate that fell onto the underside of the leaves as I held the plant upside down when transplanting it. Do you, or does anyone else who may reading this, think it worth treating the plant with a kind of standard pest spray? Something like this, which I have (soz, it’s in German…): COMPO Grün- und Blühpflanzen Schädlings-frei AF
Also, yes, window light is not good enough to grow a good plant (I imagined this was the case before, and so it’s proving to be). But isn’t it possible I might still get a little bit of something after all? Maybe not!
Unfortunately not. I do move them from east-facing window (morning) to south facing one (late morning + afternoon) when the sun is shining! And I use LED Full-Spectrum Plant Lights, but just the crappy €20 kind. Again, I’m not in a place where I can be more serious about this at the moment.
