the first 10 or 12 days you don't need to feed her anything. She has everything she needs within to get her started. a 5.5 pH in your soil is a bit low. You have time to correct it. Aim for 6.2 pH and try to keep it stable. Wide pH swings can cause stress on your young seedling. Remember, less is more right now. Don't water log your soil right now. Just a little bit around the stem will do more for your girl than douching her soil with oxygen stifling water. Keep your temperature moderate and your humidity high. 75F with a 65 to 70% relative humidity. And don't mist your plants, ever. Unless you are doing regular foliar feeding, which i don't believe carries that much benefit, as it does making things dirty and at risk of pathogen infiltration.

just keep ph-adjusting slightly beyond your intended target relative to current pH.... when it starts to even out, ph-balance to intended target. ph scale is not a straight line. it is a steep curve originalting from "1:1" ratio of hydronium to hydroxide at 7. The futher you go, th emore each incremental value means. .1 difference from 7 is much smaller than a .1 difference from 4. logrithmic scale.

Just wait'n'see if it works. ^^ Measure the PH of the soil regularly to check that it's at the level you want. Here's a chart to help you target the right PH: https://howtogrowmarijuana.com/wp-content/uploads/2017/02/marijuana-growing-ph-chart-soil].jpg
