Slow Growth, Few Leaves. Stresskiller Auto CBD from RSQ.

Only water when needed, otherwise a lot of weird shit can happen in the medium. Its also entered flower so its going to be stretching as well. Autos are ok but not the best for first timers, should stick to photo periods, gives your more flexibility and they can take a bit more abuse.

lack of magnesium, guess bad ph, see something with nitrogen and maybe too intense light. soil needs not only good wet'dry cycle, but good saturation when you have watering , aka wet cycles begining. epsom salt and some grow nutes would be very wise, would raise lights a bit till plant will start to grow more rapid and healthy.

Heyoo Mate, your light is too weak your lower leafs dying off. I would start with atleast 150W, everything else doesnt have the PPFD or Penetration you want or need to grow cannabis. a pH of 6-7 approx is better for soil and you dont water enough. Actually far from enough, and better every 4-5days than 2-3. Here a shedule how i feed my plants, just guesses but pretty close: On plant 2L in 18l soil On day 5 500ml directly on plant Day 10 500ml Day 14 750ml Day 18 1l Day 22 1.2L Day 26 1,5L Day 30 2L When the plant is big enough like 40cm, I start feeding till I have 10% runoff, mostly up to 3,5L Ofcourse you cant just start at the shedule at the day you are, because you underfed her till now and she is too small, but you definetly should feed her atleast 1L better 2L. Also you need better lights

She has probably eaten the nutrients in the soil and you have to feed her some nutrients. However I think your lights are lacking. Lumens is a light measurement for humans. When it comes to plants you want to look at lighting in PAR/PPFD and it’s measured in micromoles per second. This is what plants need to thrive. For plant that started May 20th she should be much further along than that. I’m sorry to say but these lights will not produce a good end product. But too many unknown variables to give you proper tips. What’s the temperature and humidity?
