Hey everyone, I have been growing a plant for the past couple of weeks and everything has been going great. I started her off in a plug, now shes in a local organic soil we have down here called Thunderhead. I have a nice little box with good ventilation and discreetness, and there are two 46 watt HCF lighting her. However within the last couple of days her leaves have been yellow and there is a brown spot developing on her primary leaf, which i diagnosed as either nitrogen or phosphorus deficiencies. I have been foliar feeding here and there at night, and gave her her first (very low) dose of feed in soil yesterday, however I have yet to see any signs of improvement. Could it be anything else? the Ph is a bit alkaline, and I dont know very much about the tap water here in San Marcos, Tx? I would really appreciate some help, and i know its best to get these things sorted out early.
