My ph is running 4.5 to 5 and I wondered in my ph might be too low but I've never seen this happen before and it isn't my first grow.
PPM is running 1000 to 1200 which is within the guidelines for the budding cycle and I do have some bud sites forming. I have experienced low yield in the past and figured that it was nute issues because of a lack of a ppm meter. Well I have a ppm meter now.
I have had a timer issue and just replaced the timer with a new one and was wondering could this be a light issue?
Any and all help would be highly appreciated because I need these meds.

The best pictures I could take hope you guys can help.

Hello there, I will be more than happy to help, do you by chance have a yahoo sign in?

Your ph is rather low, I usually set at 5.5 and let slowy drift up.
Lets say you set your ph at 5.5 if the ph drifts down over night into the 4's you probably have a root pathogen. (though sometimes this happens when using organic nutrients as well)

With your ph being so low, several nutrients are become unavaible to the plant.

But just dont pour ph up in your solution as you will shock the plant, you want to gradually adjust the ph back up to 5.5 over a day period.

I do not use PPM due to the different conversion scales, Do you have an EC reading you can supply me with?
looking at your plants I would give them a 12 hour flush, and start feeding at a lower ec than you are currently using,
can you take some pictures of your root system as well.

Tell me more about what line of nutrients u are using, are you dong bubbler buckets?
