Hey, to me it looks like you sprayed your plants with something during when the lights are on. If so, you should never spray plants with lights on, always have it off. Nutrients burn leaves under the light.

Manchas en hoja
Hola! Aparecieron estas manchas en una hoja de una GG#4 de zamnesia en su quienta semana vegetativa. No es algo que me preocupe, ya que la planta tiene una apariencia sana y crece vigorosa. Pero nunca vi este tipo de manchas y me gustaría saber su posibles motivos. Un saludo!

Does this look like minor leaf burn, too many nutrients or something else?
I believe two of the plants developed minor leaf burn. One has white streaks on the middle and outer portions of several leaves, and the other has a rust, reddish stripe parallel to the center of several leaves. I’ve attached pictures above. Thoughts are greatly appreciated.

Brown spots on lower leaves
Long and short of it is that I'm wondering what's going on with these brown spots on Tiamat. The solution pH has been dropping rapidly, even though the PPM has only very slightly raised (250 - 275 over the past 3 days, whereas pH has shot down from 6.2 to 5.8).

Spotted Leaves – somethings wrong! HELP!
(See previous question as well) The girls are getting worse 😬 Only the bottom leaves seem to be impacted though. Only thing I've done today is water them (three day since last and they were dry). Any suggestion to what might be wrong with them?

One of my seedlings, seedling A, is twisting a bit as it grows and has some small lighter patches on a few of it's leaves. The other seedling is growing in the same conditions but very normal in it's growth. Any idea if this is a genetic variation, or an environmental issue?
