help!! ph flux????

i am about 3 weeks into my first grow. its just a seed outta some kush i smoked. i am starting to run into some problems. the leaves are begining to become discolored. it doesnt look like its affecting any growth (but this is my first time) its just a lighter shade of green splotched on the leaves. i did some research and it looks like ph flux possibly. i will add a pic. anyone please help

damn it i put this in the wrong category

whats the ph of the water you are using? have you added any nutes? What soil are you using? What light are you using? is it far from the light?

not sure of the ph. i use purified water that sets out awhile before use. need to get a ph tester when i get paid lol but i gave it one waterign with nutes. i use the azalea camellia rhododendron plant food for veg. the problem had already caught my attention before i used nutes tho. i have only watered with nutes one time 2 days before this pic. the soil is some shit i got from a freind that grew sucsefully. its called green thumb top soil. personally i think its the soil but im a beginer. its under one 42 watt cfl about 5 or 6 inches away

Every grower should have a way to test both soil and liquid Ph. Try to get a soil Ph tester and post the reading. That said, Ph probably isn't causing the leaf damage. You're using Miracle Grow fertilizer? Please try to get some good organic ferts like Worm Castings, Bone Meal, Blood Meal, Bat & Seabird Guanos, Worm Castings, Fish Emulsion and Maxicrop soluble seaweed powder.

so if i get some of those ferts it will fix it? bcse i only used the nutes one time AFTER it had started to have discolored spots

Not that the fertilizer you used damaged the plant, that it didn't fix the problem. Check the soil Ph first as that's most important. Without being in the correct Ph range, the plant won't be able to absorb the nutrients it needs. If you bought just one new fertilizer, some Guano with N, P and a little K in it would give it most of what it needs through it's vegetative life.

thanks alot man
