have a couple plants with a couple questions..

ok guys well i started growing around 2-3 weeks ago and slowly been getting my supplies as i go along .. and it now seems that one of my bigger plants have gotten hit with something and its starting to show affect.. I'm defiantly a beginner grower..

Soil- Im using the miracle growth potting mix ( 6 month feed bag )

Water- i was using filtered water from my fridge since start of the plants .. but got the ph water tester today and found out that my filtered water has a PH level of around 8.2+- i got the cheap one from Walmart so i dont know exact points.. but i bought distilled water today and watered them with that with around 6.6+- ..

Light- 1 150W daylight spectrum CFL.. and 2 100W cfl ..

Nutes-i have the miracle gro tomato plant food (18-18-21) laying around i just dont know if thats gonna be good for the babies ..

any pointers would be great still need alot of info about growing still a noobie

yes. the ph was definitly off. But you wont see results from the ph change for about a week. Its going to look the way it looks til it has time to recover. If your ph is 6.5 then it should be good now. keep it that way and see where it goes. If you keep getting that light bleach color on the leaves then move the light up as well, although I just now read you are using florecents so in that case its just the ph most likley.
