Yellowing/browning of older leaves

[chib]

Hey everyone

I've had this plant for a couple weeks and ever since I got her she's been doing this yellowing...

I have her on half dose nutes right now and with 3 part GH series system.

She's in soil and from clone and on 24 hour light. (225 watts cfl)


The 'curly' leaves have been that way since the day I received her.



Really scratching my head at this one...

Water PH? Soil PH? What's in the soil?

How often do you water? How much? Pot size?

Grow room temp? Humidity?

It looks extremely over watered.

Your plant appears to be either over watered or under water and possibly has a pH related issue. What are you adjusting the pH of your nutrient mixture to? How often are you watering your plant? What nutrients are you using and how many millilitres per gallon? What mixture are you using for your medium? How often do you flush your medium? Have you measured the runoff waters pH?

You want pH 5.8 for hydroponic and soiless (peat moss and coco coir) and pH 6.5 for soil.
