Ik vroeg me gewoon af waarom ik groene / gele vlekken op mijn bladeren heb, ik denk dat het door lichtstress komt, maar ik ben er niet helemaal zeker van, ik geef het 700PPM aan voedingsstoffen, alvast bedankt!
Light stress, or bleaching is i think what your referring too. I would disagree what is your PH set at ? this sounds to be a PH problem to me depending on how large your plants are 700ppm seems to be quite low for a vegging plant I would bet my bottom dollar she needs more (N) in her diet. Though that is just my opinion, Light stress will cause a plant to turn bright white not yellow ant this only tends to happen to plants right next to the light. Best of luck with the rest of the cycle :) 👊
