A newbie here, just wanting some reassurance/advice. I have 4 plants, 3 weeks old, growing in soil 50cm under a 400w bulb in a small grow room with intake/outtake fans and an oscillating fan. I water every 2-3 days and mist daily, the humidity is around 35% and the temp between 70 (night) and 90 (day). All SEEMS to be going okay, the pics show one plant but all are the same. My worries are the stretching (may be due to them growing on a window sill for the first 10 days) and the slight yellow/brown mark on the larger fan leaves (could be due to me mistakenly giving them ferts too early ,won't do that again), and the lighter colour of those fan leaves. What do you think guys, am I being an overprotective parent or are there improvements to be made here? I had one die early on and don't want to lose any more. Thanks.
