Yellow leaf edgesI have a couple plants that are about 5 weeks old, and one has started getting yellow edges around the leaves. I feed them with worm tea, kelp, and calmag every other week, but it's a light dose so I think this is a deficiency and not a toxicity.Leaves. Edges burnt

Triple-leaf Speedy Chile: what is growing there? Why becoming yellow?My triple-leaf Speedy Chile (see also week comment for more info): 1. The 3 cotyledons have become yellow. I also see on lower leaves slightly some yellow tips. Nutrient deficiency? Underwatering? 2. What are the small leaves coming out of soil. Another plant? Should I remove?2y ago

Is this really a potassium defiency? Any suggestions how to deal with it?Hey Guys, need your help please. It's FD 28 and the leaves of my three White Widows show some signs of a nutrient deficiency (at least my assumption).I'm growing in living soil w/o any additional fertilizer and watering with a 7:3 mix of osmose/tap water and 0,5 ml/l CalMag.2y ago

Last week she started lightly fading yellow on a few of the smaller, lower leaves. I saw claw down leaves and figured N tox so I did ph 6.5 only for a few waterings. Now she’s turning totally yellow with some burn marks. Not sure what happened or what to do!Week 6

General feedbackAny feedback would be greatly appreciated, to me the plant looks healthy, however it is a bit small considering it’s age, right? I’m thinking it may be because of the cheap ‘300W’ light I was using at the beginning of the grow. What do you guys think? (Video end of week 6)5y ago

Drainage issueI'm not quite sure why this cup doesn't absorb its waterings when the other two solo cups are getting Watered every day. All 3 cups have no drainage. They are all grown in the same conditions.
My first instinct is lack of drainage, do I need to make some holes, bottom or side?Week 5
