PH levels..

[She]

Hello, I too am a beginner and would love to know what good ph levels are and bad ph levels? I have three auto's growing indoors three weeks old. Had to transplant due to stretching and they are way behind in growth. Look nice, but tall n skinny

Hello She. Welcome.
pH levels vary whether you are growing hydro or in soil.
Hydro you should head for 5.5 - 6.0.
In soil go for 6.0 - 6.5
There is some variation between strains so just keep an eye open that your plants are healthy and thriving.
