Problem- One of my plants has been dropping really bad for the past two weeks. I have not over watered nor under watered. They are showing some yellowing on random leaves between the veins, but green every where else. A little yellowing on the bottom due needing a little nitrogen. The other plant, same bag seeds, is perfectly fine and budding up nicely.

Help please. I don't know how to post pics from my phone. Any ideas?

Thanks everyone,
Frostie.

She looks overwatered to me. If there is a deficiency it's likely related to the ph of the water you use. However it all looked green on my screen.

 

[Frostie]

That was my first thought too but I've let her pot dry out a few times to make sure i wasnt overwatering and she doesn't seem to perk up at all.

Thanks, Frostie.

Thanks, Frostie.

If anything, that looks like a Magnesium deficiency. If your ph is good, up your cal mag for her. Magnesium deficiency will start at the bottom leaves first, yellowing between the veins until the leaf completely dies, then drop off and progress upwards on the rest of the plant.

If this pattern of deficiency starts at the top of the plant, it opens more possibilities. Manganese, iron, and zinc deficiency can show the same pattern.(I'd say one of these would probably be ph related) With phosphorus or potassium toxicity also similar(due to nutrient lockout), but usually accompanied by burnt leaf tips(nutes burn).

Thank you. Reading around more I am thinkING of supplementing them with some Epsom salts.. any tips for me?

If it's Mg deficiency Epsom salts will fix you up. I believe 1-2 tsp per gallon is standard, but I always just feed 1 tablespoon per gallon. I have a lot of Mg deficient plants.

Right on man. I will be trying this out and let you guys know how it goes.

Thanks again, Frostie.
