Here's what I see on your plant:

1. Dimples everywhere
2. Leaf edges curled upward
3. Some leaves do not have serrated edges
4. Yellowing at the tips of some leaves and at the bottom of the plant.


As stinky said you should really fill out the troubleshooting form but here are some ideas off the top of my head.

1. PH problem. You have multiple symptoms happening that look like deficiencies or other plant issues. PH problems are known to cause multiple symptoms once it gets to the nutrient lockout zone.

2. What size pot are you in and how big is your plant? Possible it could be rootbound for all the reasons stated in #1.

3. Heat stress. This one is easy as your leaf edges are curling upwards.

4. Is/was your pot properly sterilized at the time that you transplanted into this pot or the original pot you started in? It's possible that there's something in the pot that's infecting your plant and causing this.


I'm going to go with PH or rootbound. Mostly because you said your plant is growing slowly, you have multiple symptoms, your plant is trying to conserve energy by producing more rounded leaves instead of leaves with serrated edges.

Although Heatstress could cause something similar. Burned tips, edges curled upwards, slow growth due to photosynthesis rates dropping off after 85 degrees (measured at the canopy/leaf. Laser thermometers are pretty cool if your temps look fine but symptoms indicate heat stress). Being unable to go through photosynthesis could cause some of the leaves at the bottom of your canopy to start to yellow.

I'm sticking with my first answer though. PH or rootbound.

Fill out the troubleshooting form and I'm sure all the pro's on here will come gunning to help you out. I'm merely a noob trying to get better at troubleshooting sick plants. :thumbsup:
