Athosanswered grow question 7 years ago Mmm. things to improve or keep an eye on.
First don't spend a shit ton of money on expensive nutrients, specially if this is your first indoor experience, you can get a great results with just the basics. Actually move nutrients to the bottom of your "things to keep in mind".
First thing to keep an eye on: over watering, this is the number 1 rookie mistake, for a newly sprouted plant like yours half a party cup (7 to 8 o) of water is enough for 5 to 7 days; as the plant grows, you will notice the soil will dry faster, meaning that the seedling is consuming more water per day, then and only then you up the amount by small amounts (I usually up by increments of 50%, that has worked as a rule of thumb so far). Remember too much water severely restricts root oxygen uptake and this means no growth, the plants literally drowns.
Second: temperatures. This is of utmost importance. In the correct range the plants will thrive and grow rapidly. When the temperature is low, the growth slows down by a large margin. When temperatures are above 23°C (73°F) the growth is really fast. Regarding this, try to improve your lights out temperatures (I turn the lights on during the night, so the heat emitted by the led I'm using keep the indoor warm). As for an upper limit, as far as you are below 30°C (86°F) you'll do fine.
Third, use quality soil, this will feed you plant freeing you from having to use nutrients for weeks. Lighter mixes will require feedings sooner, heavier mixes, can lasts you weeks. I use a heavy mix on 3 gallon pots, and that allows me 8 weeks of no nutrients.
Fourth, save yourself a Future headache and get both a pH pen and EC/PPM meter. Always measure and adjust pH (even in soil).
Fifth. Nutrients. You only need a grow nutrient and a bloom one, the rest is not actually needed and with quality soil you can forget the grow one. Master everything above before thinking on getting root stimulators, bloom boosters, etc. In my experience plants don't need those.
