Yellow between veins

Hi all, due to my hectic schedule, this sweet amnesia haze got off to a less than optimal start and isn't looking so great. Just as some background I germinated this seed around a month or so ago in a paper towel and transferred it to a solo cup with some Coast of Maine seed starter mix shortly after. As she grew I started noticing some yellowing between leaf veins, but figured it was because I may have kept it in the solo cup longer than it should've been in there for and possibly the seed starter soil was depleted. On 3/22 I potted up to a 5 gallon fabric bag with Sohum Living Soil and decided to give her a week in hopes she would find whatever she needed in the stronger soil, but I haven't seen much improvement and I'm seeing some brown spots in the older effected leaves. I know there are two schools of thought when it comes to pH'ing water in organic soil grows, but for what it's worth I haven't been adjusting the pH of the water at all thus far and just tested some I had at it is around 7.1pH. Any one have any ideas where to start? Should I give it more time in this soil or take some action?

It looks like it could be PH related, but that really shouldn't be a problem in an organic grow, unless your water is way out of whack, and 7.1 isnt out of whack! About the only thing I can suggest is give it some more time and see what happens. Hopefully others will have some ideas.

Looks overwatered. It could be the reason for ph being off maybe?

Yea I was hoping when I tested to pH last night that it would be way out of whack because at least that would give me my answer! I've read the same thing about pH in organic grows, but I think I might just pH it to around 6.5 anyways just to see what happens!

This could be it now that she's in the 5 gallon, although she was yellowing even when in the solo cup and I'm pretty sure I maintained a good soil moisture then. I thought at that time it was possibly underwatered because I kept it in the solo cup probably a little longer than it should've been and there were a ton of roots down there to absorb the water pretty quickly.

Looks like it could be very hot soil as well.

Possibly, although it was yellowing while in a seed starter soil I used on about 5 autos. That bag has been sitting around for a year or so so unless it's possible for N to build overtime, than I'm not sure. The dark leaf color does remind me of Nitrogen toxicity for sure though.

You might be on to something, I don't think I've ever seen exactly what you've got, but it could be that there's so much N (dark leaves) in the soil that it's locking out other nutrients. The new growth looks like it's worse than the older growth. Normally when the new growth is most affected it's a non-mobile nutrient, like Ca or Mg (or Fe, or several others).

Had this posted on a different forum and had some people saying the same thing about possible Ca or Mg. I was almost positive that was it. Really, a deficiency in anything would've made sense to me seeing as how it was in a solo cup for so long but not seeing any progress now that it's in a full strength soil is a bit disheartening. I may try adding calmag in the next watering. I'll keep this thread updated. Thanks for the advice, friend!

If you up potted a couple weeks ago with good soil I don’t think it’s a lack of nutrients, over/underwatering or root issues may present as a nutrient issue but that soil should easily provide everything she needs for at least 4 weeks. And with top dressing you have to stay a couple weeks ahead of your plants needs. Food for thought

I agree. Possibly lack of nutrients in the solo cup and she did seem slightly root bound coming out of that cup, but it's in nutrient dense soil now. I tried lightly loosening the roots when I transplanted so hopefully she'll start rebounding soon!

You have some kinda build up that's throwing your uptake off. Do you use any silica products
What soil is it in now
