    hello

    my bigger plant looks like it has a problem, some of the new growth is yellowy green and the leaves are turning up at the sides

    any advice guys

    the bottom of the plant is fine,the leaves are dark green and look healthy, it just seems to be the new growth since the plant went under the 400 watt hps and i started feeding with bio grow

    the light is very hot indeed but i cant move the light any higher!!

    would putting the circulation fan pointing straight at the tops of the plants do an good

    if its from the heat you need to get more distance between the plant & light, whats the temp on the top of the plant?
