Wie geht es meinen Pflanzen, was sagt ihr ?

I would always plant automatics in the "final medium." According to AI, there should be a slight calcium and potassium deficiency, what do the other growers say? I've always followed the "fertilization plan" from Plagron, but now I only use 65%-80% of the recommended amount, meaning I continue to fertilize as usual and not OVERwater. Best regards

Always plant autoflower seeds directly in the final pot, so the plant experiences as little stress as possible during growth, since the vegetative phase is already very short. Everything else looks good.

What's happening is that you are in a very low PH level for an autoflower and to your system integrate organic compounds as Biobizz. You should be on a PH interval between 6, 2 to 6,6 ( normally you start your veg phase around 6,2 and as you go trough the weeks on your grow and facing flowering in the end you raise your PH up to 6,6 as maximum limit. Probably in Germany you will have another situation that you should be aware and once every three weeks you should irrigate your grow with some organic Cal/Mag. Keep it up. 420

They look good size-wise for day 15. But I can see from the leaves that you’re giving them too much water. They are a bit overwatered. And just a tip, never transplant autoflowers, always plant them in the final pot. Once the root growth has stopped in autos, no new roots will grow anymore.

You should always plant autoflowers in their final pot and only stress them to a limited extent, because otherwise you risk your plant not growing big enough and flowering too early. So you can top them, but only on healthy plants and starting from the 5th-6th node. You should avoid repotting if possible. Keep the pH between 5.5-6, leaning more towards 6 is great.

Hey, I would plant the autos directly in the final medium and not transplant them. It can definitely work, but as a "novice," I wouldn't do it. PS: I've NEVER done it either. The pH of the water I always keep between 5.5 - 6.5, but it's best to aim for around 6. I'M NOT AN EXPERT! MY EXPERIENCE AND OPINION! So far, I think your plants look good except for that one leaf with the "stripe," but I wouldn't do anything and NOT water too much. Best of luck and happy growing!

Cool! Please know what I share is only my opinion and I'm no expert. Personally, I'd shoot for a higher PH (preferably 6.3). I'd also use a larger pot to begin with and would advise against transplanting autoflowers. The stress of transplanting isn't worth risking on an autoflower in my opinion. The plant needs time to recover, and autoflowers don't have the luxury of time to bounce back from different stresssors without impacting yield and quality. Lastly, If they're in a small pot, you might need to water more frequently as soil can dry faster in lower volumes. Keep up the good work and Happy Growing!!
