Identifying a Deficiency

So this Thunder Cookies #2 is on day 19 from seed and just noticed that the first set of one pointed leafs had this on them. None of the other leafs are affected. Just the first 2 leafs.


So you can see it’s alittle droopy which I’m assuming is because I topped a few days ago and yesterday realized I had broken a leaf near the topped area and only one top was shooting out. So I tore that top out and now hopping it grows 2. But it’s still recovering lol

Are the affected leaves closest to your soil? Possible soil splashed onto them during watering?

Well yes it’s close to the soil but I know it hasn’t splashed.

Your plants look good, maybe a tiny bit of nute burn from the FFOF.

The FFOF soil is a hot soil, and younger plants be be susceptible to nute burn as a result. Keep doing what you are doing, don’t add any nutes. Make sure that the pH is 6.5.

If you are using distilled water. You are eventually going to need calmag.

When you water, water to runoff, and measure the pH and the ppms of the water you collect. About 10% of what you put in should come out the bottom.

You need to transplant soon. What size pots are they now and what do you have available to upgrade to?
