Hi! You probably want to check on the pH of your drain at first.. :) If it's too low, there could be lots of deficiency signs but caused by low pH. All the best!!

Cotyledon issue from seedling Have seedlings from Auto Colorado Cookies (Dutch Passion). One already has cotyledons, but not opened yet. I see some yellow and bigger brown spot of the tip. In the beginning I had 250 PPFD, could this be the issue? Now I am around 100 PPFD and put the light a bit up. See photo.

Light burn, light burn due to humidifier water lights?What do you think caused this brown color on that leaf? I have 5 leaves like that, all the others are ok. I believe it's due to pulverizing water and droplets acting as magnifiers for the light, causing small burns. Also, since they are burnt, should I just cut them out?

Many or low nutrients?Hello Growers What could it be? I thought it would be a nutrient deficiency (EC-1.0) so I picked up the nutrients to EC-1.4, but it's getting worse. Do you think they'd have a lot of nutrients?

Leaves curl, become crispy and have weird colors I need help. I've not had this problem before. The leaves get crispy and have weird colors. However, the buds continue to develop as usual. What could it be? Not all plants are affected. But it spreads slowly.
