well definatley do not add nutes at all plz i hate when ppl say add more nutes to a seedling DOESNT NEED NUTES. i would leave it for now if your using flourescent lower the light to about 1 inch from seedlings and keep the air a decent temp let them grow see what the second sprout looks like...
simply switch the lighting back to 18 on 6 off although this could shock your plant into being hermaphrodite or male depending if u know the sex of the plant or not
yea although i dont mind the longer flowering just because longer u can flower bigger the nugs will probably be but as of right now the smell of the plant is about 5x stronger then the original its really giving off the stink.
by the looks of the leaves that were pruned off kinda looks like nute burn to me although in the one pic are those holes throught the leaves? if it is bugs is right
i had the same problem was almost like the air is too dry and its drying the leaves out they feel dry...... but i left the plants alone and when the new shoots grew no other leaves had this problem and they turned out fine just the 2 or 3 leaves had the problem so i pruned them off but i dont...
hes obviously not gunna trim every fan leaf off his plant the huge fan leaves are basically useless during flowering they use up more energy then they make i trim my plants and ive never had a problem
