Stealth SoG with few auto strains

Hi krok464 You possibly facing two issues Over watering and over feeding . And they could cause slow growth. You need to act quickly. 1-Try to lift the soil around the seedlings to get more air penetration and quicker dry cleaning ff the roots. 2- get more Air circulation around the steams off the seedlings. 3- if Growing in plastic pods try punching a few half 0.5 mm holes around the pods to get more air in to the soil. 4- you possibly have room to up your temperature a little to 27C so it will help with drying out the soil quicker. 5-If nutrition burn shows up best solution will be transplanting them in new soil. Because a flush will only worsen the overwatering problem. Hope this helps and good luck with your grow. Happy Growing. If you need more help text me in PM.

Your plants are on the smaller end so too much defoliation could impact results. I would stop at this point currently. If possible, try to do some LST and spread the branches out a little bit without injurying them to let the light get to the bottom bud sites

The best is looking by yourself at the trichomes with a microscope I personally prefer them to be 30% amber color and then start flushing for 2 weeks they usually will finish with 40% amber trichomes, the high is different. It’s up to you buddy
