Guava x Sticky Soul

Build a soil has a schedule for all their amendments and when they're called for on their website. As well as Jeremy's youtube catalogue being a plethora of knowledge regarding his products.

From what I understand - the seed has enough nutrients stored to get through the first few weeks without any supplemental nutrients. If you plant into 'hot' or nutrient-rich soil, there's a chance you'll burn the plant with toxicities e.g. Nitrogen. Please take note - I have no experience with using your line of amendments, but I would wait to feed for a couple weeks at least. As long as your potting soil has enough drainage and has optimal moisture level to germinate, the plant will do the rest on its own. Also be sure to provide enough humidity and keep the little seedling in optimal temperature range - as they're vulnerable in their infancy. Good luck! Excited to see your progress.
