Hi, I wonder if anyone would be kind enough to give some advice regarding leaf discolouration on seedlings. I am mostly inexperienced growing skunk-or any plant... The seedlings are about 3 weeks into grow but don't look very healthy with browning of leaves and noticeable wilting. I'm using a heated propogator with avg temp 70-80f on 18/6 cycle. Propogator lid has been removed for most of lights on and put back on for the dark cycle as thought it would have helped during the lower ambient temperature in the evenings, possibly a mistake.. should I have used the dome at all after germination? Then there is the grow light.. I've been using a Mars Hydro 48 led approx 20" from top of plants. It seemed to work great at first but now I'm wondering if the light intensity has been to great for seedlings. The soil is a mix of seedling starter, perlite and a small amount of worm castings. Watering generally when the top soil has began to dry with bottled water PH around 6 to 6.3 and no nutrients. I have attached photos and would be very grateful if experienced growers can advise, heat stress, the led light, under/over water, nutrient deficiency etc. Thanks all, thctalk members. Phil.
