Yellowed bottom leaves patchy - is this potassium deficiency?

Nahh. I could send you a little notill starter kit. Just would need to get some cash flowXD shipping to sk from bc wouldnt be bad. All you would need is a cuft of good vermicompost (i can help you find that online but shipping is sometimes more then the product(worth it though)) some sphagnum peatmoss and some lava rock. Both of which you could find in town:) i spend about 5 bucks a run on nutrients. Ive seen people spend 200 on a runXD
