Help w/first grow

[gwr]

Seem to have a few things going on. Need some help suggesting what to do.
I have a 7 week outdoor white widow in happy frog soils using half strength fox farms soil nutrients. I PH water going in but runoff is way low. i did a nice manifold and plant is bushy and growing.
heres my negatives im worries about.
1. Lower leaves lookin a little yellow
2. Some leaves with some brown spots
3. Looks like something chewing some leaves too

I'd be most concerned about what's eating the leaves - little fuckers know how to hide sometimes when they see you coming - so look everywhere twice.
Lower leaves will whither first cuz now they are getting the least amount of light - can't make them green again so sometimes - snip snip.

yeah the nutrient situation seems fine, maybe a bit light green for a plant in rich soil fed with nutrients, so what i recommend is to start watering with nutrients at a high ph in order to neutralize the acidity in the soil. use ph up to bring the ph up to 7 after adding the nutrients, keep checking the runoffs ph and when you see it reaches 6.5 (after a few waterings, may take a couple of weeks) just keep on feeding at 6.5
