  2. growing in coco?
    looks like you need calmag supplement
     
  3. I see very dark green leaves with yellowing on the insides of the older leaves.
    Nitrogen toxicity.
     
  4. When the yellowing is in between the veins on older leaves, it's a sure sign of a magnesium deficiency. Your plant doesn't look bad for 25 days - I suggest mixing in perlite on your next grow though. Good luck.

  5. Well it's 60% peat and 40% Coco it's a mix I got from tropic so I'm not sure if it's classed as Coco or soil Screenshot_20180916-042942.jpg

  6. Peat and coco is the equivalent to running hydro essentially. No nutrients to be found other than what you add.

    Edit:

    Read the write up about the combination you posted. Very weird. I’d rather use something without slow release nutrients IMO. It seems they’ve amended the peat and coco with things to slow release. I’d pick a different option to grow in personally.

  7. With all the magnesium that’s supposed to be readily available in that mix, I would check your ph. That’s early onset of magnesium deficiency but what is causing it?

  8. What kind of light are you using? Could be the strain but they seem to be stretching just a little between nodes, maybe try topping, and I would definitely suggest LST mine are on day 28. Topped at day 21 above the second node.

  11. Light mix is for seedlings. You can stay in coco/peat, just add 30% or more Perlite at transplant. The plant looks great besides magnesium deficiency. What is your ph in and ph of runoff?

  12. Ph in is 6.2 I don't tend to test run off
     
  13. Do it next time. Feed a bit more than normal so you get runoff and test the ph. It will give you an idea of root zone ph
