whats the matter!?!?!?

could this be a cal. def.? or could it be a ph prob? help me out let me know im new to growing.

any one have any ideas?

Are you in the veg or flower cycle? where on the plant is your leaves turning yellow? What kinda nutrients and light setup do you use?

im in veg cycle. i use b.c. grow and b.c boost. im using 4 floresent uv light bulbs and a heat lamp (from far away so they dont get burn but get the heat and light) ph is a 6.3. room temp is at 70 to 80. the humidity is at about 50%. oh yea and a fan to move the air.

here is some more pics any more ideas what it could be?

The last set of pix looks like normal leaf-rub irritation. (along leaf margins) The first picture looks like either you are spraying too often, or when you water or fertilize, you are splashing enough of it on the leaves to the point of pooling. Water collects, and damages leaf if done repeatedly. (leaf tip die-off)

thats a first.

another thing is there are some holes like bug hole. ive seen 1 or 2 small black flys in there but not recently. maybe gnats? or something around there?

i keep the room at about 80 at highest and 70 at lowest. the ph is at 6.5. humid. stays near 50%.

anyone have any other ideas?

theres a recent pic of how close the lights are. could it be heat stress?

one more pic..... help you guys out?

Gnats munch on composted materials, not your plants. Doubtful it's bugs, or more the leaves would show signs, and you would have mentioned the sighting. (you've looked for bugs, right?)

Heat stress generally starts at the top, working it's way down.

You've been givin the benefit of my knowledge, but since you seem to discard opinion...good luck. :jointsmile:

But if you desire...you might want to fill-out the troubleshooting form, and hope someone comes along with another explination more to your liking. :thumbsup:
