being in with 8-ball kush and mango ladies.
one with pipe cleaner is mango.
is this a mag problem?
What nutrients are you using?
i can clearly see burnt tips and the yellowing is because it has too much nutrients not too little, i say give it straight water for a week if its not time-releasd nutrients.
You didnt ask this but like brotherjericho said these plants arent even near done and that lamp doesnt look like anything i would be flowering under.
^^ That's why I asked about the lighting, looks like what I get sometimes (just not as bad!) on particular strains under my LED panel. I typically have no issues with sativas, but many indicas cannot take the LED within a certain distance.
