Hey all this is my first post on any forum, so bare with me!

I am posting because I started seeding slight yellowing on some leaves last week but today I really started noticing it throughout 5 plants. I have not fed anything get just water @ 6.5. I have not used any Cal/ Mag this far but I have used some ”Fish Shit” and one serving of Grandmas Molasses.

But if anyone has any thoughts on what the problem could be I surely would appreciate it!


On the first pitch it looks normal but I don’t grow in dirt

Leaves may have touched the soil, and may be the normal process of scavenging nutrients and dying off. It’s normal to lose a few leaves as the plant matures, and some leaves die off naturally.

PH going in is good, and you’re feeding properly, you should be fine.


@NcBlaZe. Did you mix the two soils, or layer them? Ocean forest is a “hot” soil. Meaning it contains a lot of nutrients. Sometimes too strong for young clones and seedlings. It could be a touch of nute burn. A lot of growers, like myself…layer the ocean forest on bottom half of the pot and happy frog on the top half of the pot. That way the plants are bigger and stronger when the roots hit the ocean forest. Welcome to the forum and best of luck. But then again…your girls look pretty good. :+1:


Thanks for the responses!

@NugFlush I mixed the two soils together along with extra perlite and worm castings. I appreciate it🤙

@Covertgrower that is a very good possibility being that I didn’t see it until after starting LST.

Well your plants look pretty good, if the ocean forest was too hot, I think you would notice more issues than just a small amount of yellowing. Some strains with good genetics can handle the hotter soil, versus a seed with poor genetics. I wanna ask ya tho…what’s your opinion of the fish sh!t? I recently picked up a bottle of calmag at my local grow store and they gave me a free sample bottle of the fish sh!t. Just wonder what ya thought of it and basically…the method to your madness? How? Why? Goals? Proven results? The simple I read the pamphlet that came with it and it sounds good. But doesn’t all labels from the manufacture? Lol. Since you brought it up…I’d thought I’d ask Stay safe and stay medicated :exploding_head:
