My leaves are yellowing pretty bad and a few of them have brown spots on them. Can anyone look at my pics and diagnose my girl??

How often are you hitting with cal/mg? How often are you watering? Things looking a little droopy. Are you letting the soil dry between waterings? Have you checked your runoff ph and ec to see if there is an overload stopping notrogen uptake. Cal/mg once every couple weeks if you need it. If you check your runoff and things are out of whack then its time to flush and get salt buildup out. Refeed and watch new growth. Cheers friend

It looks like a micro deficiency. Could be any of them, but I think sulfur is most likely. Assuming the yellowing started toward the top of the plant, I'm gonna go ahead and say that this is almost a guarantee. Add some epsom salts to your feed. A tablespoon per gallon should fix her up. Cheers!

Yellowing of leaves is caused by a nitrogen deficiency. This can be caused by incorrect pH, pH of your feed water should be 6-7 for soil and 5.5-6.5 for coco/hydro. If the pH at the roots is not correct you can lockout the plant from uptaking certain nutrients. However, your plant does look a little droopy which can be caused by overwatering. Overwatering can also cause unusual deficiencies even if the pH is spot on. Soil should be dry top 1-2" inches before watering again. In my experience this was every couple/few days with soil. I measure my nutrients by ppm so I am not sure what your mix of nutes equate to.
If your soil is becoming dry before watering again, you could try to raise your ppm a little. But I agree, this yellowing is wuite early for the flower process. Goodluck man!

I need advice on what to do with this plant. I flushed her a bit and I think nutrient burining is not showing on new growth, what ppm should i feed her?I watered only last week and mesaured runoff ppm and ph. Water was 350 ppm and 6 ph and runooff was 700ppm and 6.7 ph. Before when i fed her with 850 ppm runoff was 1500 ppm.
I would continue to water only but there was a lot of yellow and pale leaves so gave her light dosage.5 years ago

Leaf damage and flower analysisAsking for thoughts on leaf damage. I think there may be nutrient shock so I will be reducing PPM to 800 to see if that helps. I am confused by other problems seen on a few leaves. I also want to ask if I am getting close to harvest (check flower pics) since this is an autoflower

Ongoing brown and yellow patches forming in week 6 of flowerI've also noticed today a couple leaves looked wet, so tried to wipe it off but that did nothing. I took 2 pictures of the same leaf at slightly different angles to see the shine. It's only the skunk effected (closed similar question prematurely in skunks diary)

They are on the older leaves and they keep getting that faded yellowing starting from the tips. The pH of the run off is 6.43 and they havent been fed a round of nutrients in a week! I thought it was a cal/mag def but they haven't bounced back after a dose. Help please!

I'm already seeing yellowing and on the largest plant, #3. Is that due to growth or am I over watering? Approximately 2 gallons in the wick bucket every few days when it starts to feel dry, but I generally spray the top with water on a daily basis, not more than a 1/4 - 1/2 cup.

If this was yours, how would you proceed?Going into week 6. I just clipped the bad leaves that show in the picture and will be switching to the growing stage. I plan to do the 36 hours of darkness first. Already changed the water and it has the bloom solution instead of the grow solution. What would you do now?5 years ago

Noticed these yellow spots this morning. Not sure if this is a nute deficiency, leaf septoria or too much light. My lights were pretty low as my tent isn't very tall. Have been watering at around 6.4 and recently started feeding a full dose of Big Bloom and Tiger Bloom.

Leaf damage/discolourationThe Skunk has been getting a lot of leaf issues. I have been trying to stay on top of picking them off as they appear in case it's rust or similar and can spread. It almost looks like cal mag deficiency, but I'm feeding cal mag each feed. This is the only one effected out of four

What deficiency is this?Earlier, I added Epsom salts to fix purple stems, I’m pretty sure I over did it and I think this is a potassium deficiency but I’m not sure. I was being cheap and didn’t change res b4 moving over. Now that they moved tents, seems to be getting worse. How do I fix fast!? Pix in di

Leaves yellowing 4 weeks into flower - a bit early?#1 Has started yellowing much sooner than expected. With 4 weeks to go, I'm not sure how much of a problem that is - what happens if I can't fix that? The other 2 are not affected and have same soil, sun and nutrient schedules. Bud production is going strong. Any remedy ideas?
