    Lets See Your Outside Plants

    Lol I'd guess you're talking to me? This was early morning, which is think can be just as good as the evening golden hour :D

    Purple leaves

    So it's a purple strain and the question is why the leaves are purple

    Help! Leaf tissue deterioration on otherwise healthy plants.

    I'd say caterpillars too. The only strange part is the concentration of holes towards the middle of leaves. My caterpillar damage is more random. I'd spray with Grandevo and BT to cover all the chewing insect bases.

    Effects of ISR/SAR at various weeks of flowering

    I understand that, and I agree that healthy soil is king. I don't understand why you're assuming my soil isn't healthy in the first place. My growing environment is not hospitable for cannabis, so I'm looking for ways to boost my plants' immune systems beyond healthy soil. It's perpetually...

    World's first cannabis cultivation trial

    The ones in gravel will probably do best because the lights are closest.

    World's first cannabis cultivation trial

    Not really. This is a test to see if the yield is higher with 3 different grow methods. The whole point of a scientific experiment is to control as many variables as possible and test one variable. Even something like having a fan closer to one setup can change the results. Introducing...

    World's first cannabis cultivation trial

    Are those lights exactly the same distance from the seedlings?

    Wondering why my plants buds are not getting any bigger after the 7th nearly 8th week into flowering

    You're looking at the trichomes of the sugar leaves. Look at the trichomes on buds instead and report back what color they are.

    Plant troubles

    @OP how often are you watering? They honestly look underwatered. Do they perk up after watering or does it get worse? My plants in fabric pots also looked like that and it was because of underwatering. I had to put them in the ground to fix the problem. When I pulled back the pots they were...

    Interesting, I know sulfur is used to turn rhododendron/azalea flowers blue. It seems like a slow release of K, Mg and S through weeks 3-9 is pretty perfect. Thanks for the info!

    CSI humboldt thread

    That's good to hear. I'm on the coast too, running three T-1000 crosses ( x Bubba, x Zkittlez and x Obama Kush) and a bit paranoid about mold.

    Anyone dealt with mealybugs or red scale or before?

    It looks like my lemon tree infestation has transferred over to my cannabis plants. I've only seen about 10 per plant so I'm picking them off as I see them, but I'm finding them mostly near buds. I'm curious if anyone else has successfully handled these while in flower? Oils are out of the...

    1st time putting in-ground; Question-

    Yea the central valley heat pulls all the cold air through the city, making it windy and foggy. That sounds like an awesome auto cross. Is it the first generation? It will take 2 more until you can get to the recessive auto gene. Happy to help you get there. First gen: AA (photo) x aa (auto) =...

    Sirtalis' California Organic Outdoor 2021

    I sprayed the girls with Regalia in the morning. Top dressed with an EWC / bat guano mixture, some barley SST and watered in the guano tea that was bubbled for 24 hrs. Going to see if they can handle a fairly heavy feeding of 0-10-0 guano. Found a small spot of gray mold on the MPU, and...

    Unsure if bud rot, looking for some guidance.

    Do you have any more photos of that full branch? There looks to be way more webbing than what one caterpillar would do.

    1st time putting in-ground; Question-

    Is there a reason you wouldn't prune the inner shoots that are shaded and will make larf? I have a plant that is getting botrytis on the inner twiggy branches because of dense foliage. I'm also coastal and my humidity does hit 95-100% overnight and I spray southern ag garden friendly...

    Unsure if bud rot, looking for some guidance.

    Budrot and caterpillar eggs. The webbing is from a caterpillar forming a cocoon.
