Rule 106.6a
Official source text from the 10 August 2018 Rules release
Some replacement effects increase the amount of mana produced by a spell or ability. In these cases, any restrictions or additional effects created by the spell or ability will apply to all mana produced. If the spell or ability creates a delayed triggered ability that triggers when the mana is spent, a separate delayed triggered ability is created for each mana produced.
