Sounds to me like you are doing it in the wrong order for your system. Sounds like the cubes suck up high PH water, then you lower the PH of the water not already sucked up, then over time the water slowly mixes the PH goes up. PH the water first, then double check it after. I would water the top of the cubes to try to push old water out to where you are measuring in your double check.

You don't really need it to begin with for seedlings. Just try to crack it open a hair for a day or two to let them adjust without sudden shock and don't over do the light when they are babes. You only really want a humidity dome when the roots can't keep up in supplying water to the top without it.

An injured plant or a larger cutting may require a humidity dome/bag.
