    Old School Skunk, who's found it???

    Are this double serrated leaves reserved for RKS only, or you can find them in some other strains? How much in percentage is that double serrated leaves, all or just some of them on one plant? Because I found some double serrated edges on mc Critical and Im curious what is this.

    Flowering point, when?

    I allready heard about that, but everywhere else were mentioned that the flushing is crucial for non harsh smoke... If flushing with pure water isn't necessary, I m glad, one worry less

    Flowering point, when?

    Ok, so I can calculate harvest time from 12/12 hour switching. I need it for stop feeding and start flushing schedule. Thank you.

    Flowering point, when?

    Hi. I don't know from which point of the timeline is runing "floweing time"? Is this the exact time when we change light schedule from veg(18h) to 12 hours or is from that time when the plant starts to show first signs of buds(first hairs or pistils)? It is around 1-2weeks difference between...

    "Rust" on some leaves

    Yes, I know what you are trying to tell me. I still think that the problem is calcium or mag defficiency. Wind was only a thing which cames nearby... :) I read as many articles as I can, but this leaf indicators could be so similar to each other. And every time I look at my plant I can see...

    "Rust" on some leaves

    I also read some comments where were saying that the mostly indica strains needs much more calcium than sativas. And I noticed here in my example that the only ICE and Domina(indicas) had this signs of brown spots. Other my less pure indicas(Cookies, Gorilla, Skunk, Critical and Unlimited), does...

    I will try to get this book and read it, thank you. Is possible that brown spots are wind burn? I have two small vents in this small space and those two most affected plants are right in the middle of a strongest air flow...

    "Rust" on some leaves

    Thanks. I did used this small pots just for this round. For next grow round I have six or eight 8l Airraps. I used this mini pods just for searching for my personal best strain. I had so low ceiling and I was afraid the plants in bigger pots will get too big and they could reach too close to my...

    "Rust" on some leaves

    Well, I use drinking water from the pipe, which could be hard, but I don't know how hard it is. I only lower ph from original cca 7.5 to ph 6.5.in final stage before goes to water tank. I mean, I mix water and nutrients and then I do some ph correction, if needed.

    "Rust" on some leaves

    Because they grow in such small pots and they have no acumulation. I think and it looks like they get dryed between watering cycles. It is also not so big quantities of liquid. As far I did some experiments, I gave to all seven plants around 2 or maybe at most 2.5l daily. Im afraid to get the...

    "Rust" on some leaves

    Yes, it might also looks like phosphorus defficiency, yes. I will take some better look, when the lights comes on. I will add some more phosphorus in the water tank and maybe some more with foliar feed, ill see at the evening, when I can come to my plants. Or, I will wait for a day or two to see...

    "Rust" on some leaves

    Thank you Roger., i will dou like you said. Are chicken egg shells also ok? I was thinking if would I boil shells, dry them and crush them to dust and then use this as additive for calcium... I edited and added some more pics in my second post. Ph of my nutrients/water mix is around 6.5.
