GrischaBXL
started grow question 4y ago
Hi Breeders, Elizabeth is growing well, but the bigger leaves are curling up at the edges. I already increased lamp hight and lowered to 18/6. Is it air humidity? Or too much water?

When leaves curl (taco) it's usually a sign of heat/light stress.

Hey friends! My middle plant is tacoing and shooting out a lot of white pistils (only plant doing so and is directly under sf4000) . Is this a light issue, phenotype or mainly a ph and nutrient ovefeeding issue as other taller plants aren’t displaying these signs. TIA!

many problems with the leaves
the leaves have been turning yellow and falling faster and faster, especially those below; the upper ones curl and become burnt with dots and turn yellow should I try to put the lamp higher? (I haven't given fertilizers for a week)

What is she trying to tell me ?
Could anyone tell me why some leaves of my orange sherbet are dying ? Is it stress (the plant is in front of the fan) or cal-mag-potassium deficiency (I don’t have neither cal mag or potassium). Thanks a lot 🙏💚

Light burn or nutrient issues? Female?
Does this look like light burn and maybe a lack of nutrients? Also can someone confirm that she’s a female or is it too early? I am first timer and think I see her lady parts already.

Curling new growth
All of my new growth is curling a little bit. I dont think it's N toxicity, but it's also probably not heat because all of them look like this. Is it N toxicity or something else? Thankss
