Probably burn. Test the EC of your runoff. Also test the pH of runoff. If EC is high, your soil is too hot and you probably will have a low pH.

Any idea what is causing this crisping on a few of my leaves? I am maybe seeing some slight curling/taco-ing on the upper leaves too? I think the PH might be a bit high in my water too, it's 7. I've ordered a filter and some PH Dwon, the PPM was only 250. Related?

Living soil and rain water problem Has using rain water killed my living soil? Has anyone got experience of using living soil with rain water? Apparently the ppm is too low (just like RO water) for the plant to take in nutrients. So basically is my living soil now just soil or is the microbial life still there?

What can I do? Leafs starting to turn yellow. First grower Yesterday, I noticed some leafs starting to turn yellow and also the tips of the top leafs to be a bit brown. So I watered (nutrition in the desc) and calmag 2 ml, because I thought it might be either lack of PK or cal mg. What else can I do? What about my watering schedule?

Top leaves turn dark and curl - What can I do?I've had Nitrogen and possible Cal/Mag deficiencies 2 weeks ago. Mid last week I started noticing some burn a the tips, so i dialed nutrients back again. By this weekend the tips of the leaves curled further and turned dark. The rest still looks a bit pale, but buds look good.

Calmag or Potassium deficiency Starting to show hard yellowing on plant #2 looks like it can be calmag Deficiency or Potassium Deficiency. I gave them a bit extra calmag a few days ago and it seams like things are not improving too much.

What do you guys think?It's my first grow (automatic, 6 weeks old) and compared to other plants, my plant looks a bit small/ridiculous. I give her 24/7 light (I read that on guides) is that maybe too much? What's your impression of her? I use two growlights (one from above and one from the side).
