my flowering plants have turned yellow and brown, help!

[Bobby44]

My plants have turned very yellow and brown of the course of four days. they are 5 weeks into flowering and were looking mostly green and healthy. i went out of town and my roommate folllowed watering instructions with ph down to around 6.7. i am currently using fox farms tiger bloom and big bloom about once a week. the leaves seem to go from yellow to brown and kinda have a slight claw look to them alll of a sudden. i dont know if its the ph or if its simply nitrogen def or maybe mag/cal def. what would be the best course of action to get this plant healthy?

High Bobby,

Second here is a ph chart that will help you to better understand where you ph should be, and what nutrient get locked out if its to high or to low:

A you can see 6.5 in soil is best, @ a ph of 6.7 you lock out manganese (Mn) & iron (Fe) which are micronutrients/trace minerals. Not having thee avalable to your plants can and will cause the issue that you are currently having. and be ure to let us know how things are going.
