1. Look for signs of bugs.
2. Replant into larger containers. Those are too small. When the bottom-most leaf layer is about 3x the width of the container, it's time to replant into a larger one.
4. Stop eating Burger King.
5. Check the PH of your soil. Take multiple readings from each container.
Make sure your PH is in the acceptable range for soil growth.
6. Look for signs of disease. (Mildew, mold, etc.)
It appears as if the plants are yellowing and browning from the bottom up. That's a likely sign of a PH and/or nutrient problem (I'm guessing Nitrogen in this case). Your top growth appears to still be green and "praying" to the lights....that's a good sign.
What sort of
Happy Frog are you using? Unlike humans, not all were created equal. Be sure you're using one with a higher N ratio, ideally the "Tomato and Vegetable" HF nutes.
How long has it been since you've given them nutrients? Immediate turn around to happiness won't happen, give them a few days after doing the above mentioned. The leaves that have browned won't come back and the leaves that have yellowed may or may not.
Good luck, report back!
