    Yellowish spots on leaves

    It came to an end :( Result was 11oz, not great but always something, I learned a lot from my mistakes and will improve a lot with the next one. Thank you Myke for all your help, I wouldn't have done it without you.

    Yellowish spots on leaves

    I'm not seeing any yellow whatsoever anymore. I'm using dutchpro A+B bloom for coco. Have a look at the table, see what you think.

    Yellowish spots on leaves

    OK I'm dumb. Myke, when I was struggling with yellow spots on leaves you helped me out and educated me about my watering schedule and advised on adding CalMag. You told me to give 2 or 1ml/L to fix the plants, I, the dummy I am somehow understood 1ml/100L and that's what I've been giving them...

    Coco - Water Temps

    I know it's a bit late for a reply but I started struggling with water temps too as winter hit. The room is quite cold as I keep fresh air coming in and that's where my tank is (plants are in a tent where temperature is automatically adjusted). I just purchased an aquarium heater where I can set...

    Yellowish spots on leaves

    A little update. So far so good. pH still hasn't changed but I'm not hoping for it anymore. Plants seem to be healthy with perky leaves. Nearing the end of 3rd week of flowering, all plants are developing buds. Yield probably will be nothing special but should be few oz to smoke at least...

    Yellowish spots on leaves

    This is my first time and I just wanted to get the basics right until I start diving deeper. I would like to see your formulas if you don't mind so I can start looking into it and making my own nutes.

    You mean just bend them so they're all the same height? I'm switching next week.

    Yellowish spots on leaves

    Hello. Thought I would update you again. I've attached a photo this time to see what you think. They're 7 weeks old now. They only look this yellow under mh bulb, don't have a way to take a decent photo with normal light to show true colors.

    Yellowish spots on leaves

    At least I learnt a few things and I'm going to continue to learn. That's right, they grow really fast, they were just tiny cotyledons 6 weeks ago. I'm probably going to see even faster growth next time as I'll have coco where I can actually control the pH.

    Yellowish spots on leaves

    Believe it or not I just sat down and thought about giving you an update. My plants are now all very well and healthy, perky leaves, nice colour, the yellowish spots have disappeared. The pH run offs are still high but plants seem to be doing well regardless, although I will never use pebbles...

    Yellowish spots on leaves

    This means I have few weeks left to figure out how to keep the humidity level stable, may just need to experiment with the fan speed while lights off. I was thinking of purchasing another fan, a smaller one, and plug it into an Inkbird humidity controller but that's a bit of an investment.

    Yellowish spots on leaves

    tornado 1500m3, fan controller is set to 22 as it measures the temp at the top of the temp and it gives me constant 24-25 apart from that 27 spike which I still need to figure out. Additional heat source while lights off will be beneficial as it's a bit cold then, 17.

    Yellowish spots on leaves

    50-60 during lights on, jumps to 80 when lights are off, I've just ordered a dehumidifier, didn't have that problem when I was watering once a week but now it's building up when lights are off. I just read that cupping can be caused by higher humidity and the plants are trying to 'sweat' so my...

    Yellowish spots on leaves

    Hmm, I peek to check temp more or less every hour and it's never above 25 when I look, however over last few days my hygrometer says the highest temp at some point was 27. I've been trying to figure out when. Relocated the fan and I'll try pinpoint when my temp goes to 27 so I can eliminate this...

    Yellowish spots on leaves

    Keep in mind plant 1 was flushed yesterday, therefore lower ec than usual. Generally ec not looking too bad but pH is high, no help for that I guess. New problem is curled leaves with brown tips. Copper deficiency? It's on plant 3.

    Yellowish spots on leaves

    I'm at the beginning so not even thinking of mixing my own nutes. I just want a fairly healthy grow on pre made stuff and learn (so at least I have something to smoke) and then I'll get into more advanced stuff. I've heard coco is harder at beginning than soil but easier once you get the hang of...

    Yellowish spots on leaves

    It's my first time and I've read it's better to go with less than too much, but according to the chart I think it's safe for me to try 1100 for a few days and observe, if nothing bad happens then increase.
