after reading the first post i lowered my light and ripped down the tin foil. i got rid of the dead leaves. four days on and i have seen a massive improvement, new growth all over the top of the plant and down the stem. if there is no hope for these plants how do i go about cloning so i can salvage something. i have researched it but i have found so many ways of doing it and dont no which 1 to try. thankyou all for all your help!
