started grow question 4y ago
The coloration on my first leaves is worrying me. First grow. I really don't want to stunt her. G&B potting soil, filtered soft water, Myco+ in my water, 100w AC infinity Ionboard.

Looks like its getting a bit to cold for her. Temps below 16C/60F will cause stunting and hinder nutrition uptake.

Problem with plants in the 3rd week of vegetation.
I'm posting again because I accidentally marked it as resolved. I was using BioBizz CalMag from the beginning, but when I switched to Advanced Nutrients, I stopped because Ph Perfect Sensi Coco Grow A and B already contain CalMag.

Gray leaves on buds with a massive concentration of trichomes. What is it?
No clue what this is. Light gray leaves, tons of trichomes. I'm a bit confused here. Should I just cut the buds that look like this to be safe? Or is this normal?

Dunkle Flecken auf den Blättern.
Hey.. On one of my White Widow plants, dark spots have been appearing on the leaves for days, and today I've also noticed the first spots on a Blue Dream.. Can someone tell me what's going on and how I can get rid of it? Removing the affected leaves hasn't helped.

Leaves are getting dark
Leaves are getting a little dark and cotyledon seems a little sad. I suspect it is caused by not watering her enough (i was only spraying her with water the first 4days) Any advice?😀

My seedling doesn't look so good.
This is my first coco grow so could be possible that I made a mistake. The other three seedlings are super healthy but this one has this weird thing with it's leaves. Somebody seen this before? I gave them some root juice and fertilizer before transplanting with ph between 5,5-6.

The problem in plants when I supplying CO2
Hello! After adding CO2, I noticed problems on the leaves of my plants. Grow in coco+perlite, water with 1100ppm solution, 1000ppm co2 in air. Drain from the right 1400ppm and 1800 from the right. Is it related to co2 and irrigation system?

Blackening leaves on 2 week old seedling.
Any ideas what has caused the blackening on the leaves? More effects of the overwatering? Hope it's not a lost cause but I'm losing hope.

Yellowing to slight grey leaves
What's the cause of the older yellowing leaves with some grey and the slow spread to the newer growth? I'm between pH problems and or deficiency but not too sure.
