I've got a Pineapple Thai X CD, a Chem D X BananaOG, a Chocolate Covered Strawberry and three Bag of Oranges X Panama Red that I started about a month ago. As you can see in the pics, I’m getting yellowing and dried out tips on the lower leaves of these plants. I think the likely cause is nitrogen deficiency, but I don’t know for sure. Could use some help determining the issue and hopefully resolving it. (I’ve tried to provide all the details I could think of, so I apologize for the length of this post.)
These plants are 28 days old since sprouting. They are primarily growing indoors under an LED light, though I began taking them outdoors for short periods everyday since 5/11/22 to get them used to sunlight. For the first couple of weeks, they were on an 18/6 schedule, but I’ve been slowly lowering the hours of light downwards so the plants don’t flip to flower when they get transplanted outdoors. Towards the end of May, they will be transplanted outside, in the ground in No-Till soil.
The soil in the cups is year old Soil King Baby Big Rootz mixed with a small amount of worm casings (maybe a 1/8 ratio). Up until 5/16/22, I only watered the plants with water or water mixed with a small amount of Harmless Harvest coconut water. The water was filtered and Ph balanced. About a week ago, I started to see some yellowing and brown tips on a few of the lower leaves. I figured it was time to start feeding them some nutrients. On Monday, 5/16/22, I watered using a tea I made. I placed about ½ teaspoon each of Neem, Kelp and Alfalfa meal into a cheese cloth and let it soak in a quart of water for 24 hours, stirring periodically. I then mix the tea, at a ratio of 1/5 with water, and Ph balance it. Today, I again watered with this concoction. I’m thinking this tea should provide enough nitrogen and other nutrients, but that may be a bad assumption on my part.
I’m trying to wait another week before planting them in the ground because daylight will be closer to 14.5 hours where I live. Once in the ground, I know they will get all the nutrients they need. Maybe I’m over thinking all of this.
Does this look like nitrogen deficiency? Do you think my tea should be providing enough of the necessary nutrients that these girls need? Should I just stick these into the no-till soil and put this issue in the rear view mirror?
Any help and advise will be truly appreciated.
