Hey man, I had been giving them 1.5ml a + b for coco combined, I have sinced upped it to 1.5ml of each per 2 liter and she is looking much better, also been giving 0.5ml of clamag every other feed and foliar feeding a few hours before lights on come on each morning with nitrozhyme. When I fed her yesterday I added 3ml of rhizotonic in with the a+b and clamag. Have a look at her now in the pics below, what do you think? She keeps burning on the fan leaves for some reason but all the new growth seems a nice dark green like you said. I had previously burnt the said fan leaves in the early stages.
Thanks for looking
Edit: Just seen in your previous post you mentioned the red stems, you are right, it's on the fan leaves. I noticed that last week it does get a bit cold in the room they are in, could it be that? Temps when lights go off goes down to about 18-19 degrees celcius, when they are on they are around 25-27.
