Seedlings are not growing after 2 weeks?

If you’re growing your seedlings in coco coir, keep in mind that it contains virtually no nutrients. That means you need to start feeding them from day one and pay close attention to the pH of your water, as coco doesn’t buffer pH like regular soil does. You have two options: 1. Start feeding your plants with a nutrient solution specifically designed for coco substrates. 2. Transplant your seedlings into regular soil. Personally, I recommend Canna Terra Professional as a growing medium—I’ve had great results with it and can highly recommend it. Keep growing growmie

You are growing in coco coir. It has zero nutrients. You need to fertilize your plants from pretty well day one. Coco growing is basically hydro in a potter.

Having a tiny plant in a large pot makes watering properly difficult. If you are not watering all the way down to bottom, you are doing it wrong for sure. If this is soilless, also need 10% runoff. Water a small circle around plant and increase as it grows. Despite the common belief that you should not transplant an autoflower, You really should treat it like any other plant. They, like coco are not magical and do not require unorthodox behaviour. In 300-400ish transplants, i've yet to see 1 plant get "shocked." You'd have to use some sort of g.i. joe kungfu grip action on the rootball or maybe throw it against a wall while transplanting to cause shock. If you don't ride the short bus, you'll be fine, in other words. Also, even in coco you want 1/3rd perlite. Coco on its own does not have sufficient aeration properties. These do look small for 2 weeks, if that is accurate - 2 weeks from sprouting? If nodes are not spreading out, reduce light slightly. The "stretch" is your guide to light intensity. This looks like coco coir, which is usually an inert substrate and requires you to provide 100% of nutrition through fertilization. If this is the case, you need a well-balanced formula every time you fertigate and get 10% runoff out the bottom, religiously. This avoids build up over time in the substrate - no flushing is ever necessary. That's a pretty stressful thing to do to a plant and should be avoided as best possible. If you ever have to do it, it should be in response to a pretty serious problem. Basics of watering -- fully saturate, wait for appropriate dryback and repeat. If you wait for the same loss of weight between irrigations, you will use the same volume of water. Do not choose the volume. You give what it takes to get the job done. Partial or suprficial watering is bad behaviour and will only lead to problems. With the added complexity of a tiny plant in a large pot, you attempt to water a smaller circle around the tiny plant. While it helps, it does not prevent water from absorbing into a wider volume of substrate below the surface, obviously. This leads to very long periods of time between irrigations, which is not ideal for the root zone. IF you don't water all the way done, you train superficial roots, too. So, it's a damned if you do, damned if you don't situation that is soley caused by listening to some bro science, lol. I say this with 100% confidence you can do a transplant without issues : Only a retard would fuck up a transplant... you are gently placing a root ball in a larger pot and covering it with more substrate. This is not stressful. Make sure roots can hold the media together and don't do it when it is bone-dry and it's easy as pie. So, if this is coco coir with no nutes pre-amended, it's most likely a lack of nutrients. Start feeding a well-balanced 1.3-1.5 EC fertilizer formula. This is not high enough to ever burn a seedling as long as you don't drip it directly on the growth tip above ground. If you don't want to fertilize on initial irrigation you should at least start on the 2nd. It is not a "hot" concentration and probably less so than anything it'd experience in the wild, so more than robust to handle it, too.

honestly everything looks good to me. they may be going slow but i think theyll survive and youll end up with a harvest under your belt. maybe increase light intensity and give a very low dose of nutrients like 1/8th of what is on back of the bottle. start doing that every 3 days unless it creates adverse effects. also jack up the humidity to like 70% baby plants love high humidity and will benefit from it

Hey Growmie, It could be overwatering, especially early on—autos are super sensitive at this stage. The soil looks pretty damp, so I’d let it dry out and lightly water around the base. They might bounce back if the roots catch up. Don’t give up just yet!

24/0h, 7-10k lux, watering under stem could be overfed if u haven't flushed the soil
