    Have you fed them any heavy nutes lately? Or have your temps had any spikes that you know of?

    I’m thinking Nute burn tho... I had something similar and it def wasn’t light burn

    I fed them a full strength bloom feed last night. With half strength cal-mag ph'd to 6.0. It's only affecting 2/4 autos , a ak 74 auto,And a northern lights auto. What should I do? flush at 1/2strength nutes Just keep giving it PhD water.

    Could be leaf septoria. I would rule out nutrient burn by doing a thorough flush, then resume feeding at half strength nutes. If the new growth continues looking like this, then it's definitely not a feeding problem. In the mean time, do you have time/resources to quarantine the unaffected plants? If it turns out to be septoria, it'll spread like a fungus I think.

    Also, what's your setup like? Soil? Lights? Ventilation?

    Could be potassium toxicity through the roots from over feeding though

    I’m still learning tho. I make small changes and see how it effects it.

    I love all the help I'm getting. So I guess I'm gonna flush with 1/2 straight nutes . And back the lights off. I used a 100x scope to check for mites already. Thanks guys

    Nute burn norm starts on tips and edges.. light burn can yellow leaf, bleach, or fry it crispy lol. I’ll post some pics of mine. Basically looks like his pics. Part was bc I was using half strength nutes. Went to full strength and the plants weeks behind it(same clones) didn’t get the spots. About 5 week into flower leaves started curling up and showing signs of to much light intensity. I moved them up and it stopped.

    The two effected, are they bigger(taller ,bushier, more bud spots?)
     
  18. #18 PureHeaven, Dec 31, 2018
    From my first grow(same clones as these) I’ve learned half strength nutes in flower don’t work! Both times I’d get brown spots like urs ASAP once flower started. Atm 5 plants in week 10. 2 week 6. 2 week 5. 1 week 4, and 3 week 3. All same clones. All the ones after first 5 started getting full strength nutes in flower and all of them have zero brown spots and look way healthier then the first 5(10w) did at same time

    Here's better pictures. The first two are the affected ones
