    Check your run off EC, I suspect that it is above 0.9, if so, reduce your feed

    I agree with MC, looks like a salt build up, and probably feeding toomuch, or not getting enough run off from your feed, or even not getting rid of the run off. Test your run off EC on the next feed. Is it all over the plant or in one place?

    Its only on the 1st nodes leaves nowhere else, I did run out of dechlorinated water a few days ago and did not have enough to get adequate run off so that may be the issue

    Could be splash burn. I doubt it’s over feeding with your base at 0.5 and total Ec 0.9 unless you’re not getting run off

    Could also be light or wind burn if its just in one localised area of the plant. Make sure your fans aint blowing directly at the leaves, and oscillating. And of course making sure your light is far enough away from the top of the plant. Let see what that run off EC is saying later, thats the most likely cause I think

    I currently have my 400w MH 13" away from them, is that too close?

    I have another question, I'm wanting to top these plants and scrog, they were repotted a week ago but are getting near to the 5th node coming so should i repot into final pots now so they have time to settle and destress ready for topping? or is 1 week not long enough?
