I'm having an issue with some other plants, t...

You need to be careful with feeding when so young, I'd advice to wait two weeks before adding nutrients. The seed and soil contain enough nutrients for the first 2-6 weeks. They look like they're stretching towards the light, try and reduce the lamp to plant distance. And don't spray for bugs! Hey done sticky yellow stripes out helped me out a bunch, caught hundreds of little bugs!

As you say "with some other plants", these gorilla breath up here aren´t the plants we are talking about? Hard to tell what to do. If you mean these plants here i can only see bug tracks on your leaves you already sprayed. But they need some mor light intensity and some wind to strenthen the stems. If you mean other plants you should check your drain first with a ph-meter. Many problems at once are often caused by a nutrition lockout due to a wrong ph. If so, correct the ph of your nutrition-solution to about 6.5 . If its not the ph, you should feed them with N-only nutrition 2 times till the N-deficit is gone and no more burnt tips appearing. Then go on normally.

Hi @StonerAlien! Don't be a chemical freak, sometimes less is more, especially with such young seedlings. Your babies are suffering from lack of light, you can't fix this with nutrients, you need to decrease your plant-to-lamp distance, and/or increase the power/wattage of lighting in your environment. If you're growing by the window, I would recommend to consider buying a LED grow light. As for nutrients, it's always easier to fix a slight deficiency than to recover from a toxicity, so I would suggest to focus on good soil + good pH and see how the plant reacts week after week. No nutrients but root stimulator for the first 10-12 days. Hope this will help, let me know in the comments section if you need any further information. Happy growing! 👊

Hi, shortcut: no nutrition before week 3 or 4... ok and now explained. As you are growing in soil, and transplant the Girls, they get their nutrition from the soil, so normally there is no need before floweringis near to feed them. My solution will be... Give them a biggert growingpot and they will look fine.. Get some airflow to strengthen the stems, get closer with the light. The stems looking very weak , that because they stretch for the light. So taslant them, dig them deeper, get some airflow or shake the stems daily to stregthen them. Otherwise your plants fall down. ....... for later... if you reached the final pot and your older leaves show some yellowing you may start feeding.. but take a lower dosage to look how the fertiliser work and how the plant responds.. ahpy growing

From pic I am not seeing any type of defeciency. But if u r yes u need to flush with pH distilled water or ro water. Then resume feeding but half of what you are using then go up from there. This will solve your overfeeding. Also when growing in soil you don't need to feed seedlings till week 3. Good potting soil will contain enough food for the seedling till then.
