I need help with my plant. The leaves used to be very dark green, and they are yellowing, they are reducing in color, as well as spots of yellow. Also i think i might have over watered them. Too much light? 400W HPS 24/7. Too hot? 77F....Oh by the way its about 5 weeks, had 4 sets of leaves and recently cropped...to get more grow

Have you fed any nutes to your plants? It sounds like a nitrogen deficiency. Check out the GrowFAQ link up at the top left, there is a section for identifying plant problems.

You know at first i thought so tooo, however, I added bat guano...it reads [IMG]file:///Users/ruslangogichaev/Desktop/J_720265.jpg[/IMG]
10 - 2 - 1

total N -10%
5% H2O soluble i added it yesterday

Phosphate-2%
potash-1%

If you just started the bat guano yesterday it will be a few days. The yellow leafs will stay yellow but you should not see any more new ones. On a side note DONT cut off the yellow leafs they still are doing some good for the plant.
