Hey guys, hope I can find some assistance here with my first grow. I planted two strains on the 25th March, both auto fem seeds, after germination. One is original AK, the other is auto blueberry. I was not able to get grow equipment before or even now during lockdown in order to grow them in a controlled environment unfortunately so I decided to grow them by my window sill with lots of light. I'm fully aware that window sill grows don't come with very large harvests and this is my first grow so I'm not expecting much. My plants grew a bit 'leggy' and stretched out for a while, and wasn't sure what to do other than just dig down a bit deeper and carefully lower the seedlings leaving about a fingers worth of stem and plant above the soil. This was done a few weeks ago, and while they seem healthy now and have slowly gotten more leaves, they aren't getting taller and judging by the white hairs it seems to be going Into flowering mode now as a result of the days getting shorter / nights getting longer. So this is a little upsetting for my first grow but you live and learn so it's okay. I have no way of checking ph balance at the moment, and I do have nutrients which I'm wondering should I also start using that now? How can I get my plants to grow a bit taller, more leaves and atleast a couple grams of bud? Maybe 10 or 20 grams atleast? I have them in 5lt pots in some soil mixed with a bit of dolomitic lime and some river sand. After this lockdown I will be getting a proper grow environment and doing proper research and going about it the right way. How do I start/how often should I feed these plants nutes? Every time I water? I know i have to water when the soil is dry, so no problems with the basics. I just want them to get a bit taller now and look a little less like seedlings. The plants each have about 10 to 15 leaves each, but very small and the stem is still seedling - like and thin. I can't seem to attach images, so i hope my post helps thank you so much in advance for your help and assistance!
