Leave colors on 3 week old clones blackberry Kush in Coco coir and a jiffy disk
Sudden yellowing and discoloration of a e or 4 week cutting. I water it when I see the Coco getting a little dry. I make sure there is at least 20% of run off water. I watered with pH corrected water to pH of 6. I also add a small amount of canna bioryzotonic for their roots.

Normal Yellowing?
Is this leaf yellowing normal for mid flower? I’ve been feeding her Greenleaf Nutrients MegaCrop, Sweet Candy and Bud Explosion with some GH calmag.

Scared of bud rot
So my last harvest last week had bud rot and I noticed my Royal jack has a lot of yellow leaves but I think she still needs at least one more week to grow. Could this be bud rot even if I don't see any other signs? Should I do an early harvest just to be safe?

Week 8 (4 weeks into flowering) - Possible Nitrogen / Cal-Mag issue?
Plants show signs of what i assume to be a deficiency. Stopped feeding nitrogen Week 7 according to schedule. Symptoms are not on every leaf but some the upper foliage. Yellowing, burnt tips and rusty spots. My guess is lack of Cal-Mag & Nitrogen. Is my guess correct?

The leaves started to turn yellow from the inside out. I don't know if it's a disability or an overdose. I'm using Biobizz. Someone solve? Is it in flowering with about 5 weeks to harvest, is it worth stirring or better leaving it like this?

Yellow/brown and crispy lower leaves?
Some of the lower leaves on my Purple Punch Auto are turning yellow/brown and crispy (day57-58). The one pictured has just developed like this—I trimmed a fan leaf yesterday that was in bad shape. Any advice would be great!

Struggling with deficiencies (nutrient lockout?)
Hello everyone, I need your help. I've been growing 2 Green Gelato Auto from RQS but I've had some deficiencies for a while now. It's my second grow and it's the first time that I adjust the pH. They are in soil and I'm feeding them with Biobizz liquid nutes at a pH between 6-7.

What could be causing yellow leaves at the bottom of my plants. Deficiency? Are in soil that supposedly has weekly specific nutes baked in. Any help
Most plants in my grow are yellowing at the bottom. One plant in particular is showing what i would call severe stress. I think I figured out that I had an air flow issue causing plants to keel over that was easy to fix. The Bushy one is North shore Maui and the big one is GG.

Iron deficiency?
This A.M I treated her with a cal-mag mix due to yellow leaves. Today the leaf showing symptoms "tacoed" a little bit and the tip curled upwards. Same symptom on a few other leaves but only on the tips. Iron deficiency perhaps? PH'd soil on 3 spots: 6.6, 6.18, 6.3. What to do????

Why are my leaf tips getting bleached still? I have the light 18 inches from the canopy which is what is recommended for veg, and that's only around 400umol/m2s but the leaf tips keep burning. Temps are low if anything, consistently between 65 and 75 farenheight.
