    Default Whats wrong with my plant since clone

    Ive had this plant for a week now and ever since i transplanted to larger rockwool the thing has just gone wrong not to metntion having to feed it without a ppm or ph meter for the first 4 days but now all is good
    can someone tell me whats happening it appears its going yellow from new shoots and spreading out.
    Ec. 1.4 now dropped to .8
    7 day in veg
    ph 5.8
    feed 3X 1min 6 hours apart

    anyone know what this is from im sure its heat stress and nute burn but why the yellow?

    well you've provided a couple of snippets of info needed, but you dont say what nutrients your using or how high/low the temps are, this info is necessary too ok

    i can tell you that its not heat stress from the look of the plants in the pics, but it does look like nute burn happened, id guess your plants aren't getting enough of one or more micro nutrients, primarily Iron (Fe) and Sulphur (S)
    but until we know what nutrients your using this is only guessing

    Thanks dude. Is there a chance of those green leaves which have a similar look to nute burn as they are not at the tops and going brown on edges its only happened to a couple and the tips are rolling down and up.

    Someone said overwatering and Fe is the problem. How do i add more Fe ????
    Also is 1min every 6 hours too much feeding especialy as the ring i got around the stem is about 20cm in diameter and has 15 holes in bottom at 4-5mm each
    Should i make holes smaller? Should the ring be smaller? Maybe the water aint reaching the small roots as of yet which is causeing it not to get.

    Im thinking of flushing the whole rockwool with PH of 5.8 no nutes because my runoff after feeding is about 7- 7.1 is this normal or should the run off be the same ph?
    cheerz

    Here is an update of whats going on now.
    Growth seems to be coming back on one plant but the other is slowy changing to good so im happy as you can see the new shoots are green but down near the bottom im still experiencing crispy tips and curling up and down.
    Im changing my feeding to only twice a day for 1min as i think the time where i cannot check it, i think the ph is jumping up to 6.8 locking out Fe.
    Anyway heres some pics thnx guys

    it does look like an Iron (Fe) deficiency, but it could also be a case of overwatering along with cold night time temps
    well like i asked in my previous reply, until you tell us what nutrients your using, its going to be a job to say whats wrong
    your pH rising to that level isnt good, do you leave the water to sit for a minimum of 24 hours before adding your nutes and pH balancing?
    what are your max/min temperatures?
