First grow. Something is wrong with the leaves - looks like scorched.

Beginning of burning due to incorrect feeding. Watering and feeding every day is the issue. Water/fertilize the entire pot until run off and then do not water again until the top inch to inch and a half have dried out again..........be this one day or ten days. When growing in soil a schedule of plain water/plain water/fertilizer/plain water/plain water/fertilizer etc etc works well. Also, "root juice" is a supplement that should only been given every 10 - 14 days, not every irrigation.

Leaching is a process that consists of the superficial washing of mineral salts into the deeper layers of the soil, mainly by the runoff of surface water. In this sense, leaching causes losses of nutrients from the soil, the main consequence of which is acidification. Certain nutrients are more easily leached into the soil because, due to their chemical properties, they have greater mobility throughout the soil profile.One of the nutrients that suffers the most leaching is Potassium (K+). When present in the soil solution, the nutrient can be lost through leaching according to the amount of water, the dose of the element applied, the texture of the soil and the cation exchange capacity (CEC) of the soil. Potassium generally does not leach through soil significantly, especially in clay and silt soils, as it tends to be adsorbed onto negatively charged soil particles. However, leaching occurs in soils with low cation exchange capacity. Each time you water because you have low cec soil, K+ will leech further down the pot each watering if you blanket feed from top. Roots will only reach about same size as plant, as above so below. Probably the pottasium nutrient you need is in the pot its just that its leeching out of reach. Eventually your rootzone will fill the big pot. Just a possibility that crossed mind. Wish you best of luck with the wee bonnie lass. Gluck.

Mobity applies to both nutrient deficiency and toxicity. What i see presents as a mobile nutrient. Brown spots look familiar to nitrogen toxicity being they form on tip first distinctive🤔,but I'd expect a darkening of the green and possibly red/purpling of the stem if it was toxicity. Maybe it's just early. Only other possible nutes that cause spots like that are calcium but that immobile and presents across the leaf not the tip. Pottasium fits too but I'd expect a little more yellowing with the brown a little darker. People like to think of K as flowering nute and that's true it mostly is, also responsible for tugor pressure and cell expansion, your plant does look a little stalky so it could be she is running low on potassium, the pressure created from transpiration is what drives cell expansion so it could be having a hard time with the internal waterworks if there is no pressure then nothing extends much in that cycle. Add a little Extra dash of k to balanced feed see how she responds. Or apply K foliar see how she responds overnight before committing to a choice. Hmm

Either watering to offend or not enough nutrients more likely your watering not enough to often. Make sure to water the soil completely so 20% of the water runs out the bottom Then wait till soil is dry and pot is really really light then water again

Looks like a combination of early nutrient burn and maybe low humidity or light stress. The dry brown patches on lower leaves are typical of hot soil or overfeeding early on, especially if you're using pre-fertilized mix. The white tips and browning on upper leaves suggest either light being too close or low RH causing edge crisping. Let the medium dry out well between waterings, avoid extra feedings for now, and check your light height and airflow. It’s still early – they can recover fine.
