Brown/burnt spots on 1 plant only

jeannoTapinstarted grow question 3 days ago

Hello, D49 (out of 70 theoritically) same strain, same nutes but only one plant looks affected (top right). Looks like it started 2 or 3 days ago. Could it be nute burns ou some kind of lockout? If yes should I flush or could i only give tap water for a few waterings?

Hi bro, I'll start with your soil mix. Nutrients are typically used at the beginning for light-mix soil. If your soil is already rich in nutrients, you can harm the plant. In the picture, it looks like you also have light stress. Raise the lamp higher or reduce its intensity. Water the plant with pH-balanced clear water a few times before returning to the nutrient mix. Good luck, buddy.

First grow, random seed, no idea if it’s auto or not, and wondering if I’ve over fertilized.Hello grow masters! I’m on my first ever grow, and on a slim budget. After buying some equipment, I decided to try to germ some old, random seeds to start, and buy good feminized seeds when I have more cash. 1 female worked out, but no idea of strain or if auto or not. Is it ok?

What is happening to her?I noticed a few stains starting to appear. The old tips are kind of burned and the new are a little yellow. I fed her with a compost tea but with nutrients on it, maybe was overfed? Could be PH issues? It's possible, I couldn't take the ph on the last two times I watered her.
