ThatBritishEntstarted grow question 6 years ago
Most of my new growth is showing yellow tips as can be seen in the photos, some older growth is also affected. Some tips are also curling under. I believe this to be nitrogen toxicity or light burn but would love a second opinion, what do you guys think?

Really dark green leaves, check. clawed leaves tips, check; yep you have nitrogen toxicity. Stop feeding, give plain water at least until the leaves turn light green. Also, I think you could also have signs of wrong pH, there are a few leaves with curled edges; get a pH meter and check your water and feeds pH.

Why suddenly curly leaves ?My S.A.D have not looked good for a few days, the leaves are curling up and some of the leaves are turning purple / red. Is that because of the cold? Last week it was very cold and rainy, between 6 and 13 degrees. Over-fertilization is impossible, I have only fertilized minimally

Plant growing weak (leaves); don't know what to do / to expect with herOne of the plants I'm growing is looking feeble. Leaves are growing thin and she drinks less than the others. Same strain and same growing conditions.
Seedling was stuck in his seed's hull and I had to remove it myself, scrunching a bit one of the cotyledons. What should I do ?

Top of plant chewed offI woke up this morning to the top of my Passion #1 seedling chewed off by birds. Is still worth growing? I can't imagine the amount of stress that plant endured. It's a rare strain so I'd like to try and finish it but not sure if the juice is worth the squeeze?
Thank you!
