New Grower Can someone take a look at this?

[AFNG]

Problem: I see some yellowing on only a couple older leaves.

Medium/grow method: Organic soil. 5 gallon pots using nature's care organic raised bed soil and nature's living soil Super Soil Autoflower Concentrate mixed into lower third of pot.

Feed: and supplements used: None

water source: Tap water left out for 24 hours. Don't have PH meter but know I have hard water with minerals.

Strain/age: Trans Siberian from AutoSeeds 37 days old.

light used: I have 2 SF1000 lights in tent.

Climate: Mid 70's with 45% humidity

Additional info: I have been tucking some leaves to allow more light to certain spots.

I did some some light yellowing at tips of some leaves so I raised light a little and that's fine now. Only these couple lower leaves are currently having issues. The rest seem fine and she is seems to be chugging along.

Hey from what I've read about it is that its most likely a nitrogen deficency because they are older leaves but it could also be K+ or Mg.

I just took some pictures today too.

I've heard of people growing soil only sucessfully. but I think it requires regular topdressing to keep the nutrients levels up.

natures living soil causes this when using layered method..might just grow out of it. water with a tablespoon molasses per gallon every other watering or better yet brew a compost tea n use that..might just be the miracle grow was hot in some spots..
i used nls and had same issues.. ive seen it other places as well..same issue.

Do I just leave those leaves or take them off?

 

[1337timmay]

I would leave them because they are still good and will be absorbing light

Hey growbro you gotta lil more than yellowing going on. Them brown spots could be a problem for your ladies. This has been my best resource trying to self diagnose problems. https://www.growweedeasy.com/cannabis-symptoms-pictures
In my totally un expert opinion you got something blocking uptake of manganese.
And naw them leaves won't recover, watch the new growth to see if you've nixed the problem.

It's definitely spreading on lower leaves.

I got some Dr earth pump and grow organic fertilizer 3-2-2. Put 2 squirts on soil and watered.

How long to see results if it's working?
