Update N Qs

Here's the latest shots of my gal, looking really nice when u can look up close, nice bush, lots to look at. i have one of those PH testers and its showing in the 6 range, slightly acidic. How do i counteract that?
Also the centered leave in the second shot is curling, why is that?
Some of the older growth curled on account of the temp i think but this is fairly new....As always im open to any n all help/criticism

1Buy some PH up.

2You need to start giving your plants nutes if you havnt already, and if you are try something different. Basic tomatoe plant food that you get anywhere would get those looking alot better then they are just mix it at 1/4 str.

3Dont worry about every leaf on the thing after all it is a weed!

The fert comment is mostly directed at the second pic as I dont notice it as much in the first.

Ive been using jacks blossom booster 10-30-20
1/4 strength and every other water i use plain water
