I've grown outdoors since the late '60's. I recently went indoors and bought a computer. So, being a veteran, (though not indoors), I say you are doin' fine for your first grow so far. After the Ph problem is fixed, you should be gettin' ready to add nutes in the next week or two.
Good job, (besides Ph mix up, we've all been there. Myself at least 20 X's) you are doing what is expected of a first time grower.
