3rd week veg complete but still so small. What am I doing wrong?

Need to add a taste of nutrition about day 10 to 14. Then continue to add based on size. Usually half recommend dose on bottles. Also need to test run off water ph to know soil ph is to prevent lock out. I would keep going so you can get more experience vs starting totally over and repeating. If you select my answer feel free to message me and will happily help with anything i can. Good luck and happy growing 🌲🌲🌲👊

Oh and also just to further my point. "Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. Water is necessary for plants but only a small amount of water taken up by the roots is used for growth and metabolism. The remaining 97–99.5% is lost by transpiration and guttation." .. Cannabis uses about 99% of the water it intakes for Transpiration the other 1% is used for metabolic and life functions. Plants Need water.

Yup I agree with Cachimbo.. Your mistake was your feeding,. Cannabis likes Calcium but it doesn't love Calcium.. And excess nutrients will slow any plant down. So it's like there is enough Water.. You can't overwater cannabis.,. You can only suffocate the root zone. So unless your doing daily watering and not letting it dry out.. Then it's from the Calcium.. Any seedlings.. Iv'e started over 50 seedlings and I can honestly say they want/need and thrive on only water and sunlight. Our natural impulse to want to influence and make things grow faster causes what your plant did. I hardly ever use Cal-Mag because I am so adverse to how over used it is.. Save your wallet. save your plant.. use less nutrients :).

Your soil is lacking nutrients if it’s turning yellow at such a young stage. I would add add nutrients with a higher (N) npk. Also try moving the light closer. A 1-1-1 formula could help also

Scratch that, I took the liberty of looking at your stats. With the TS1000, you should be 24" or so away.

Hi, that could be from the nutes too prematurely, lights to close or in too high, wrong conditions—- too cold, not enough humidity, etc. Good luck ✌️🏻💚🌿

IMO the issue started when you first gave the seedling Cal-Mag. You should be giving nothing to seedlings until they have their 3rd node. https://www.rollitup.org/t/giving-cal-mag-to-seedlings.992130/ Hope to be helpful
