i have litte babys that are a week and 3 days old...looks like on the outer edges of the leaves there getting a brownish color and on the tips of 2 leaves there starting to turn a yellowish color.....should i start givin them nutrients or are they too young for that?
Add just a very slight bit of nutrients and stop watering them soo much, that looks like the problem to me.
i have a thing that tells me how dry they are but really how much should i be watering them every week for the first month? there under 24/0 light with 125w 6400k and 4 23w 6500k
