Same here,Some yellowing is o.k. I did feed them last night, and today I just watered!! Look healthy and strong! I will be giving them two more feedings of nutrients and then water the last two and weeks, They are a ten week strain but you can pick at eight..I shall see.. the temp is 82.3 in there this evening with humidity at 48% they have great circulation and The light is about 14 inches above them..They were watered with a P.H. of 6.0. I go by weight of pot as far as how much..They like to get almost dry before being watered again (S.S.H.) the rest like to be a little moist..
The N.L. is my baby, I got her in Feb from a Disp, I had it in hydro, then put her in a bucket outside for a month,She got some bugs in the soil so I transplanted in the 2 gallon and look at her now 28 inches and the stalk is as big as my thumb, With 3 side Kolas and 1 Main Kola..I have two clones from her Im going to mother..
The Cyber Crystal is fruity smelling and very pretty..Slow though..
The GDP are very main Kola type plants and smell like a gum,Very sweet and yummy, You just want to eat it!!!
