Thanks for the info. https://www.roguesoil.com/launch-pad-components this is the web page of the product and whats in it. I like the idea behind it. If the manufacture of your nutrients has a soil based feeding guide line check it out and see what it says. You may run into salt buildup in the soil when using liquid fertilizers, as they don't drain out of the medium as well as a soilless one. To fix that if its becoming an issue you will need to flush your medium. This is the feeding chart for botanicare, they also have a soil based flower feed in the same lineup. https://www.botanicare.com/documentation/pure-blend-pro-soil-feed-sheet/ **When using Silica Blast, always add Silica Blast into your reservoir FIRST followed by Cal-Mag. If Silica Blast is not being used and Cal-Mag is, Cal-Mag should be added FIRST, then add the remaining nutrients** This is a snip it from a blog giving suggestions for feeding guidelines. They also stated it was important to read your plant as well in case it wants more or less. Early Growth 400 - 500 ppm 0,8 - 1 Seedling 500 - 600 ppm 1 - 1,3 Transition 600 - 750 ppm 1,2 - 1,5 Vegetative Stage 800 - 850 ppm 1,6 - 1,7 With soil grows dry amendments works really well in them like Gaia Green or Dr.earth even Down To Earth, these brands are fantastic. I am not to familiar with liquid nutrients in them indoors. I used liquid nutrients in soil on my balcony for a few years before switching to whole organic items because it can hurt the soils microbial life over time. With that said they loved it and did very well for the first two years. amazing vegetables and flowers. third year not so much. If you plan on tossing the medium after the grow this will not be a problem for you. I think you are on track to doing well. The plant might have just need some extra food and now it has some. will take a day or two to see it recover. The feeding chart says it wants more but the PPM is within range. Maybe next feed only give Grow and skip on calmg and silicon for one feed. Good Luck and Happy Growing!

Nitrogen and magnesium deficiency is the most obvious to me, maybe just increase your nutes a little, check your ph is all good, you got a fan blowing on it too? It looks a little "weak" 🌱👍

Could be a bit hungry? It's just a guess though. Few Questions I could not find in your diary: What are you growing them in?? brand and breakdown of the soil composition. What was in the lite feeding you give them in week 3 dairy,just compost tea? how much of it did u give them? What is the PH of the water you are watering with? and how much water? How do u plan on feeding them in the future with what nutrients? With the above information we should be able to help you out a bit better. Cheers,
