Hi guys, I was hoping someone could help me this, I've got two plants about fours weeks into flowering. Both are are yellowing rapidly and have been for about two weeks now, apart from that they seem fairly healthy, buds developing nicely and the fan leaves sticking straight out. I know the leaves start yellowing during the flowering cycle, it just seems its happening a bit too soon. They are 18 inches tall, 1 gallon pots in FFOF, I know my pots are a bit small and that could be contributing to my problems, I've been following a tight nute schedule using AN, micro, grow and bloom. I gave them a flush last week using 6.5 ph water, measured the run-off ph and it was 5.0, my question is how can I raise the soil ph?? could i just put water in at say 7.5-8.0 to balance things out, or should I use something else to do it. I'm thinking that the soil being so low is causing lock-out or some other kind of problem.
I'd really appreciate some help with this.
Thank you.
