2 month old dieing??

i really hope you guys can help me out. this plant is almost 2 months old from a 2 inch clone. i've been using it for a mom to take clones. she was veged under 3x23w cfl's . MG soil with MG nutes 24-10-16 or sum shit like that. she was doing really good for a while and than the very bottom leaves started dieing. i assumed it was from no light and now these black dots are popping up on older and new growth. oh ya and please dont say pest problem unless you know for sure lol i've sprayed and checked all over for any little fuckers

the bottom leaves look like they arent getting enough light but they are done for already. the brown spots look like ph spotting before nutrient lockout... what is the ph of the water you are using and the ph of the runoff/drainage water?

i have a ph meter but i've been told its a cheappy but it says 7 and when i stuck it in my soil it was about 7.5-8 and i dont really water till it comes out the bottom should i start???

i read on peakseeds that you should water till 10% of the water leaks out

wut does the ph need to be at and how can i lower it i just went to the grow room and my soil ph is at a solid 8

it needs to be 6.2-7.0 in soil...i would add in dolomite lime (main agent used to buffer ph of soil and keep it around 7.0), the soil mix most likely came with it mixed in already but after about 2-3 months it doesn't buffer soil ph very well anymore. also, are you using liquid nutrients or is that a time release you added to the soil? if you use liquid you might also consider ph adjusting the solution... also, adjust the ph of your water to 7.0 or a little lower when you are watering. that should hopefully take care of your problem. 6.5-6.8 has always been the target i try to shoot for... once you start getting up over 7.0 it can cause some probs.
