If you are at 6 weeks there shouldn't be too much feeding left to do. It's a normal part of the life cycle for the larger fans to yellow and die off in late flower. If I were you, I would probably just feed pH'd water from here on out so as to not compound any problems you may already have. Also, you don't want to pound nutrients and make a flush before harvest impossible. Take em another couple weeks if you can, on water, and give em the chop.

Have you looked at your trichromes under a scope yet? That'll tell you how close you are to harvest.

Have you done any transplanting in these plants lives?

How long have they looked the way they do? When did the leaves begin to die off?

Are there one or 2 strains growing?

Just some questions to help out with the analysis.
irydyum Reviewed by irydyum on . HELP!!! Nutrient Lock Out? Hi. This is my first grow, and I think my girls are very sick! My set up includes a 600w HPS bulb with daystar reflector. I am growing in Fox Farm Ocean Forest soil, using tap water which I let sit overnight before using. I switched my lights to 12-12 on May 15th, so I am 6 weeks into flowering. My ph is stable at 6.8. I had purchased Humboldt Nutrients Bloom, and had been adding 3ml/L of water. Now I am having a severe problem with leaves yellowing and dying. I am watering once every three Rating: 5
