Plant leaves tacoing, plus yellow spots. Looking for advice.

    Hi guys,
    This is my first indoor grow so I'm extremely new. I have grown a couple of time outdoors and read a couple books so I understand the extreme basics but that's about it. My issue started on my biggest plant and has started to spread to my other three plants. Basically, the top leaves began to taco and fold in, the very tips started to point down and a couple tips started to yellow. The leaves are kind of rough and the edges are slightly bumpy. Also on some of them, I have noticed some purple close to the base of the leaves on new growth. These issues aren't extreme yet, but I want to stop whatever is happening ASAP.

    Some content to help, the plants sprouted on 4/20, so they are a little less than a month old. They are in 7-gallon pots with 420 organic soil which I added some bat guano too. At around 2 weeks or so I also gave them some Floralicious Plus but haven't feed them since. Right now they are getting 18-6 light, with each one getting about 30,000 lux from LEDS about 2 feet about. The humidity is about 60-65%, with daytime temp at 75 degrees and night times at about 67-68. The water I put in is tap water that has a PH of about 7.1. two days ago in an attempt to solve my issue I half flushed the biggest one, and the runoff was about 5.7-5.6!!

    I have two theories, one being that the PH change is shocking the plants, and the second being that gave them to much nutrients to start because it seems that they are all having various signs of different deficiencies which leads me to believe that there is too much and they aren't able to properly absorb anymore.

    Those are obviously just theories and I'm extremely new so that might all be off and would love some help and advice. Thanks.

    target ph is 5.9
    5.7----6.1 stay within this.
    PPM's for small plants around 350 going to 500 at the time of 12/12
    RO water is prefered, but tap can be used if it has no chloramines in it, they will not leave the water and will kill the roots.
    inspect the roots make sure no rot is starting and no light can reach the roots. I use great white for the roots but there are several good ones out there.
    I think PH is your problem.
    If you add new water and the ph goes low, nutes are too strong, high then raise PPM's if the rooting system is pure white and healthy. Oh they will get stained with the nutes if a bit to strong.
    Finish the plant at around 750 PPM's

    Shit mis-read, you are in dirt. PH is still your problem I think, disregard the PPM info

    Thanks for the advice. Yea I gonna start focusing on getting my PH in range. About what range should my water going in be, and what range should it be coming out as run off? I think 5.7 is crazy low for run off but I was also trying to flush it out so Im not really sure.

    And what are chloramines and do I have to worry about them with soil. I just use tap water right now, mostly because Im not trying to constantly buy gallons of distilled water ever week. Do you have an alternative youd recommend?

    I think your instincts are spot on. Over fed. Soil gives you the freedom to say screw the ph, I'm watering.

    So would you say I should flush? Or is it acute enough to let it handle itself and focus on balancing out PH? Cause 5.7 run off I feel like is super low compared to a 6.2-6.5 range for soil.

    The tackling on that one plant is heat stress check your temps make sure you got air flowing through their good

    Thanks for the response. I thought there might be some heat stress but the temps stay between 68- 75 degrees during the day. Could the heat stress be from light intensity? A lot of reviews on the LEDs I'm using said that they were extremely intense and they are only about 2 feet off the top.
