Slow root growth, yellow new veiny growth. purple stems/feel like wood

  1. Hi there. been having some issues with my plants about the lAST week or so,
     
    Slow grow. new leaves looks a rough and wavey.
     
    What do you guys think?
     
    They are Texada time warp/ Northern lights from Peak BC seeds. Its not strictly an indoor strain. Like they grow in in Kewlona and stuff here in BC. ..... anyways. I think theres somthing wrong with my ladys.... They want to grow. they are trying to grow. but there is just somthing holding them back....... Ive only fed them 3 times in their life ( besides teas) because they just havent been seeming to be really able to handle them...

    I just transplanted from 1 gal to 3 gals and i notice the root ball was really small for 2 months. like barley even pot bound :?

    Anyways heres the specs.

    800 watts -> 400 hps 400 Mh
    promix HP with 5-10% worm casting
    3 gal square pots
    Advanced nutrients grow mico bloom - ph perfect
    19/5 light cycle.
    1-2 tsb dolmite lime per galon of soil.
    Watering with ph tap water at 6.? ph. i use the General Hydro drops and I look for a yellow color.


    So.... After that.. what do you think is wrong with my plants? Grow SUCKS! super slow. NEW GROWTH is the affected area. OLD LEAVES ARE FINE.... New growth is all yellow and veiny and skinny.

    My stems feel like wood! like i couldnt even clone theses plants if i wanted to.

    Petules ( stem directly of the leaves) are red/ purple

    I flushed 2 weeks ago and have just been giving water. 
    ---> i think its somthing to do with the Promix SOILESS mix. like becoming to acidic from the peat or not having enough nutes ect.

    Please any help would be great!

  2. The pics are kind of small, but from your description I might guess that you have too much magnesium and calcium. All pro-mix is pre-limed, so adding more might have thrown off your ph a bit and added Ca/Mg (2 tbsp per gal is a lot, even in a mix that isn't pre-limed, unless you meant tsp). I don't know the source of your tap water either, but if it's from a well then it probably has a lot of Ca/Mg in it already. If your water goes through a softener then the added salt will cause lockout, even if you PH it. What's the PH of your tap water before you adjust it?
     
    If anything, it's an immobile nutrient since it's occurring on new leaves. Likely caused by lockout through an imbalance between your soil and the water you use. Have you tested your runoff PH?
