Soil week 9/10

Can anyone help? I've been trying to keep in veg state until I can fix the problem. Started in miracle grow so 3/4 of the 5 gal bucket is MG and 1/4 is Foxfarm I've been putting on top, when I water her the soil sinks alot and the bottom of the bucket feels light.

Kinda looks like u gotta ph issue. But what's your concern specifically?

Bugs being outdoor but everyone esle is saying PH also. So its probably a mixture of both

I don't see the issue
