Space Bucket auto flower now transferred

Looks like your pH might be a little wonky man. 3 fingered leaves + yellowing + possible cal/mag deficiency points me to that conclusion. Maybe she is a little hungry for some nitrogen depending on your soil and watering frequency. In my opinion those brown spots look like an early stage cal/mag deficiency. Light stress or burn turns your leaves tips and edges white first, then the leaf dies. If you Google light burn cannabis, you will see it looks really distinctive. Best of luck on the grow. I love space buckets. -G

Ta muchly been looking at different teas you can make with different ingredients and techniques etc. Need an air pump me thinks. Very interesting. Thanks again

Looks like you're off to a great start. I have heard about this space buckets. I will be following along. Best wishes on the grow.

Almost looks like you have an air circulation issue. Is your grow getting enough fresh air?

I've got a 4" USB fan that is on a timer and is only on 4 hours a day(might increase the time to 12 hours on and 12 off) and I have a UFO led which the fan has been turned upside down to act as an exhaust fan.
