hey everybody just fed my plants with 6.5 ph water and nutes. so I decided to see what the runoff was and it was 5.9 is this something to worry about? plants are in 3 gallon containers in soil

Pics and info. Everything you can from nutes to temps, age etc.

Could be nutrient build up and could be soil makeup.

okay, where do I start....apparently I have been watering them with about 7.6 ph water up until a few days ago not knowing because I was waiting for my ph pen to come in the mail, next is nutes I was using some stuff I got at the local hardware store, I can't remember the name off hand i will have to look for the bottle. as for temps the water temps are in the 70 degree mark. tent temp is usually around 78 degrees. my neighbor brought me some fertilizer today that brought the ph down to 6.5. I think it was called grow more or sure grow, something along those lines. that's what I fed them and phed the runoff. as far as soil goes, it's a mix of BG. about 50% Black gold 25% coco and 25% perlite. so far, indoor growing isn't my strongest skill. LOL

What are your night temps that's quite a bit of purpling in the stems. They look a bit hungey

I'm not sure on the lights off temp. I would ASSUME it's about 65 degrees. I will take a peek tonight when they go off. they have been purple since I've got them but haven't really had any good nutes for them to try to bring them out of it. and I'm sure the 7.6 ph water didn't help any. I ordered some advanced nutrients 3 part nutes and some cal-mag Friday. also have an EC/ppm meter on the way but it got delayed and won't be here until Wednesday.
