Think about the volume of soil in the earth man....I am a big fan of saying bigger is better. The more natural nutrients the plant can pull outta the soil without having to add any. No chemicals from this end man... Thats why led is going to be wonderful. More natural nutrients in the soil, last longer, less water, etc. etc.
What size pot are you using? Yeah, the led may be extending the ripening a bit, that switch should def. help man. I fought mites for a year once...it was a year of nothing...try after try after nothing....grrrrrr
Anywho...Jumbo be rockin bro. I feel your pain...
Best of luck Irish. you deserve it for doing what you've done thus far. Many people have swung the way of the Jumbo. I don't think they will be unhappy.
Peace mang!
