Hey, guys, can you please help me with my problem?
I'm growing from the seed for the first time, I've always started with clones before. I successfully germinated, put them under CFL for a while, now they're under 600W MH lamp.
Setup
- 9 Bubba's Gift plants from Humboldt Seeds
- 110x110x160 growbox
- 600W MH lamp (Superplant)
- Coco
Fertilizers
- I put just a small amount of Jungle in da Box fertilizers + Supervit.
- pH 5.8
Now the problem:
Symptomps:
- Slow growth. I literally didn't see any change for a past weeek.
- Leaves curling as you can see on my photos
- Branches are very close to each other but that may be a problem of the strain
Dates:
- Seeds germinated on 7.10.
- I put seedlings under 600W on 16.10.
^ this means the plants are almost month old. Are they supposed to be this small?
Probable causes / What I tried
- At first I thought the plants are freezing. The MH lamp doesn't produce much heat (it's in cooltube) and I use a humidifier that produces cool mist. Cool mist is the first thing I thought is the problem. I stopped using the humidifier for like a day or two, but it didn't help and humidity dropped to 30 % so I turned it back on. The temperature is 20.5 - 24 °C. Humidity around 50 %.
- Because of the cold problem, I closed a window a lil' bit. Not entirely, there's still a gap. But, I thought that maybe plants are not getting enough air. However, opening window didn't help and I used this technique before with much bigger plants with no problem.
- After reading some articles, I suspected my plants are suffering with bud rot. However, roots are not brown or slimy and there's no smell.
- I'm 90 % sure it's not overwattered or underwattered. I water them every day with little bit of water and fertilizers and next day, they're almost completely dry.
