Seem to be having a problem with two of mine nine girls: yellowing of leaves between middle and top. I just repotted all of them today as they were getting a rootbound (mainly at the bottom of the pot) in their previous containers. 3 days earlier I fed them at 1.2 EC with some Plagron Grow and Roots and the yellowing started about 2 days later. Please refer to the attached images for a better idea and a list of growing details as follows:

Strain: C99 (Female Seeds) and Utopia Haze (Barneys)
In Veg for : 34 days from sprouting
Seedling or clone: Seedliing
Growing in compost or other medium: Somas soil mix
Water : RO water
pH of the water + nutrients you give: 6.5
EC of the water + nutrients you give: last feeding EC 1.2. Before that EC 1.0
Temperature lights out/lights on: Lights OUT = 24C. Lights ON = 25-26C
Relative humidity: between 65 to 55 %
Nutrients, which and dosage: Plagron Grow, Plagron Roots, Plagron Phytamin.
pH of the medium (if you know how to measure): +/- 6.5
EC of the medium (if you know how to measure): recently repotted to a 2.0 EC medium. Before that it was lower..dont know.
Symptoms you see on your plants: Yellowing of leaves as per pics
