waaaaaaaaaaaaay too much fertilizer. You see how the tips of your leafs point downwards? Also the leaves look super dark green which also indicates nutrient toxicity. I only Measure E.C. so i don't know how much that is, but it's obsl too much. Lower the nutrients, maybe try 1/2 strength and look how it develops Good luck on that!

My tap water is about 400ppm(yeah it's pretty hard lol). You have other issues going on. I suspect your pH has been running way outta range for awhile.

I am growing in organic soil with gaia green 4-4-4 at 1.5 tbsp per gallon of soil. My other plants are in same soil and not showing these symptoms. Is this a cause for concern? 1st grow

What’s going on here?What’s going on with this one bud on Cotton Candy Kush plant? It has some leaves dying. No damage to the stem & only bud looking this way. It’s on day 50 of flower and has been getting lighter leaves overall this week. It’s supposed to flower 50-60 days, according to the breeder.

What kind of deficiency is this?It has been like this for 5 days or so. It looks to me like Iron deficiency but I don´t think that´s probable. I flushed her in order to get rid of salt excess but she didn´t recover any. TIA

Could someone help me to identify the issue my plant has?This girl isn't looking healthy anymore and I need to figure out why. What I did: I topped her pretty early but she recovered well (you can see it in my grow diary). A week later I transplanted her from 0.5L pot to her final autopot 14L. After that she had a hard time recovering.

Lower two sets of fan leaves have gone yellow, leaves on internodes in between haven't changed colour. Not sure what's causing this. Nutes? (3-4 more weeks of time released nutes in soil) Too much water? Did water a bit extra because I wasn't going to be home for a couple of days

Flush or what to do ?Advice please. I watered yesterday but the stains on the leaves are getting worse. Now I don't know if it is deficiency of cal n mag due to nutritient lock out which might be due to ph being off as I have 5 reders and all of them show a different thing. 🤦‍♀️...or it is it rust?

Browning leaves? Did a soil slurry and dropped the water from 6.8 to 6.2. Does that mean it’s locking out? How should I go about fixing this? In peat pearlite and worm castings. Added about 6 cups of lime to the 20 gallons of soil thought that should have helped the ph?

Forgot Worm Castings until 22nd June, implemented with top dressing of Gaia Green Power Bloom and All Purpose. Overwatered at stem for a week or so.

Am I taking the correct steps?I think this is due to a combination of overwatering (1l per 24 h in 60% Light-Mix, 30% coco, 10% perlite) and possibly overfeeding (used close to recommended dosage). I have let her dry out for almost 2 days and today watered 0.5 l plain water ph-ed to 6.5. What do you think?

Can anyone tell me what's going on in week 2? I transplanted and each plant seems to be yellowing on the lower leaves. Not very happy. Was dry when I took it out of the dixie cup and watered with 1/4 strength veg nutes and a root stimulator. It seems to be curling in as well.
