Hello,

I was wondering if anyone could help identify whats going on with plant.

Facts:
Seeds sprouted 4/19/21
Media = Ocean Forest
Pot= Fabric Pot
Strain = Green Crack
Location = Outside
Amendments = Alaska Fish Fertilizer 1tsp/gal every 3 weeks or so PH 6-6.5
Conditions: It has rained a lot

Description of the Issue:
The leaves started yellowing which I thought was due to the crazy rain we have been getting. I kept an eye on it and now that its drying out its not getting better. The yellowing has started from the bottom. Now the leaves have developed brown spots and crispy tips. The yellowing seems to start at the tip of the affected leaves and moves inward toward the stem. The new grow at the top seem t look great but the yellowing seems to be moving up the plant slowly.

I am thinking this is either:

1. Nitrogen deficiency because the yellowing is moving up the plant from the bottom. This doesn't seemlikely because I have added the fish fertilizer which is 5-1-1 npk unless its lock out see #5

2. Magnesium deficiency because the leaves are yellowing and there are brown spots.

3. Leaf Sporia because the speckling of the brow / black spots

4. over watering because of the rain

5. Neut lock out because the PH is not correct causing either item 1 and or 2.


Any help would be greatly appreciated,

I'm thinking you're got two problems: Low N and something else (maybe a pest) causing the brown spots.

It's hard to see without a closeup of the affected leaves, but the brown spots look like they're following leaf veins. Have you scoped them for pests?

I had to balance a diet between two plants on the same reservoir and had to drop my N for one of them. This same thing happened to the one still stretching. Eventually she cam out of it but with all that being said I would think it is an N deficiency with some over watering from the rain. This is just a guess in my part. Otherwise she looks pretty awesome!

Also if I can give a suggestion? I would elevate her some for better bottom drainage when it does rain.

Ill try to keep an eye on the Nitrogen input going forward and hope the rain holds off a little. Ill try to post some more up close photos this evening.

The plant is actually on a small stand under the fabric pot to let it drain easily.

I lightly raked across the top layer of soil in small areas at a time and look very closely and I could see the larvae moving. Had to look very close but def seen them. Once I moved the dirt around I seen a couple gnats fly out and I knew right then what it was!!

Hi, I have only 2 years of growing under my belt but I was thinking that the reflective light and heat from the deck could be just a bit too much for the lower leaves. I know how hot those decks can't get in direct sunlight. Maybe raise it up on top of a stand ? Hope all went well with this grow! Wishing much luck from upstate N.Y!

Flush flush flush and start with feeding balanced nutrients. Check ph AFTER adding them to water.
