Be as specific as you can about how you have been growing this plant.

Dont just post a pic and say what do you think.


Tells us about everything that you can.

TEMPS
NUTES
MEDIUM
RH
PH
SIZE CONTAINER
AGE OF PLANT
etc

anything you can think of that may help us to diagnose your problem.

Also do you have any pests?

One more thing.

What has your own research lead you to believe this is?

Have you even tried doing any research?

Nutrient Burn

Flush your plants with WATER ONLY, discontinue nutrients, and continue this flushing regimine until the problems cease

When they do stop, you can continue feeding again but aim for 1/4-1/2 the recommended dose of nutrients you are using until the plants are bigger, more established, and requiring more nutes to support their growth. Right now they are not going to need much.

sry new here

im in foxf soil 40% happy frog 40% perlite 20% , 1000w per 9 plants, temps are any where from 68 to 85 , sealed room, im using tank co2 with controller an ppm monitor , humidity is usually at 65 fighting that one every day.. 12/12 for 4/5 weeks now just switched using open sesame now to bestie bloomz. as soon as the lights come back on 2 hrs, i will check the run off for a proper ph i do believe it was 5.9 when i checked 3 days ago , i do unfortunately use straight tap water to flush. ph going in, has always been 6.8, I have looked online for over the last few days to only be more confused with this issue. i took multiple leaves with me to 2 grow stores and they both gave me different advice/ products completely the first gave me cal/mg supplement, he said due to the fact that im using the full fox farm line down to soil nutes and schedule Im having a mg deficiency, the other gave me Alaskan hummus and super-thrive . here in week 4 of flower this is not good . it started about 5 days ago, spots were closer to tips on say 20 leaves all together only on 3 plants , now 5 plants and most leaves are infected with what ever is going on .. im using fox farm to the T under 1000w hps 24 inch away . no pests for sure unless in the soil and there not visible . any help would be much appreciated

Looks to be cal/mag defeciency than nutrient burn . Nutrient burn doesn't cause dark dead spots like that .

Ya those tips are burnt bad. They don't look like that if it's a calmag defeciency. It's tricky, as the leaves look somewhat similar to both scenarios, but I'd have to put my money on nute burn over nutes. It's up to you whether you want to try the flush I recommended above, or if you'd rather try adding calmag first. Both are taking you in an opposite direction than the other, as I think you should be pulling excess out of your soil, not creating a buildup of other nutes.

Keep us updated!

I agree with this recommendation.

My thoughts on the matter are usually flush first wait it out for 7days to see any improvement if there isnt an improvement and it appears to get worse then look at deficiencies.

That sir is a fungal infection, you don't see it in marijuana near as much as you do in other plants but it still happens. The best way to handle an infection is fresh air and to cut back on your watering for a few days (let it dry out almost before watering) Sure you can use a fungicide but the infection you have looks to be systemic and just leaf spot which is usually easy to fix without chems.

makes sense, i have thought that too, but its only one strain outa a bunch its happening to, thats been the confusing part the whole time. anyhow i just cut co2 an opened exhaust for a few days..lol and i just flushed half the room......coulda fueled the fire.. SO i probably need to exhaust air at night? im completely sealed and use an ac so up to now the only air exchange is when i open the door. thanks for the advice . i will update with conclusion.

plants look ok ? you may have slight Mn def. so for fucks sake dont add more Mg.
MANGANESE (Mn)
Necrotic and yellow spots form on top leaves. Mn deficiency occurs when large amounts of Mg are present in the soil. Foliar feed with any chemical fertilizer containing Mn
