Hey fellow growers hoping someone can point me in the right direction I have 1 female plant under a 250 watt hps it is almost in its 3rd week of flowering since its last feed of Canna Terra Flores ( I'm growing in soil/perlite ) at a ph of 6.1 it has started to show signs of yellow leaves at the bottom of the leaves and dark green at the tips. Is this from to much nitrogen? Ph problem? Magnesium or iron deficiencies or is it normal??? I don't have much indoor experience but I'm trying to learn as much as I can. The room generally sits around 24 degrees C or around 75 degrees F for u guys on the other side of the world. Any info much appreciated cheers!! Sent from my iPhone using Grasscity Forum
