Nice pics, that's how mine used to look p until a couple of weeks ago. Lol. What should I expect to see in the plant if it is recovering? Obviously greener leaves but anything else that indicates I am doing something right? Well... I listened to what you had suggested, let's hope it pays off and I get some lovely vanilla kush
Well the yellow leaves will wilt further and fall off , you should see new growth appearing from the centre, little clusters all curled up , the thing is nobody can be a 100% sure of a perfect cure for your plants ill health , 1 thing is for sure, your plants will appreaciate what you have done , if you overwatered, problem solved , if you overfed and caused nute lock , problem solved , you have improved the quality of your grow medium you have a 50% better chance of growing a healthy plant,
Next thing is getting your feeding right , i strongly advise you read someone's journal/grow diary who has grown vanilla kush to see roughly what kind of feeding pattern they like , this would be useful , be careful with canna nutes , they are very strong i use canna pk13/14 bloom and canna terra flores as a 2 part nute , but i gotta say i hate the stupid bottle and measuring system , they are crap , it spills everywhere , burns the crap outa my skin and unless you use a syringe its really hard to gauge accurately , normally for first time growers i would advise a 1 part feeding nute , but as you have spent the money , go with them just be careful ,
Are you currently running the light 18/6 or 24/0 ? i advise 24/0 for a week if you can manage it , or if you have to run 18/6 try to break up the 6 hours dark into say 2 parts of 3 hours , the more light you give them now the better they will respond.
