Yellowed bottom leaves patchy - is this potassium deficiency?

Good vermi compost is hard to come by. Most stores have garbage. Before wasting 30 bucks call or email the company that makes it and ask them what they make it from. I spent 90 bucks on 3 bags of peat moss that has been run through a worm binXD and lava rock you can get at like home hardware or a garden supply store. Also landscaping companies have tons and if you ask for a 5gal bucket usualy they laugh and give it to your for freeXD raindeer naturals in vancouver is where i get mine. They ship it. Costs me like 25 a bag and 35 for shippingXD worth it in my eyes though. And the ratio is 1:1:1 ewc:peat:lava rock. Make sure to amend the ewc before adding it to the mix. I would send you the amendments when i get some cash:) most of it you can only buy bulk (which i did)
