got some sick looking leafs :(

i got several leafs, both fan leafs and the ones on the shoots, ill show you the pics cuz they speak better than me, lol, i dont know all the terminology and im baked

im 30 days into flower, 250 watt hps, 4.5ft, 3.5 gal bucket, soil hydroton mix (75/25), flora nova nutes, water every 4 days, i have gnat problems but i dont think thats it since iv had them for a long time...theyr pesky but i cant seem to get rid of em

2 pics of the leafs and one of my 2 babies

thanks for any help guys

if it has spread to the smaller fans next in line age wise on the branches, good chance is either K or mg. either one exhibits almost the same thing until later in the deficiency.

Are you checking your pH? This looks like nutrient lockout caused by low pH -- look at the red in the main veins of your leaves -- this is lack of Phosphorous.. not cuz your soil doesn't have any, but because your pH is probably too low for the plant to pick it up. Your leaves can't get nutrients up into them, so the plant is breaking them down and feeding off them to drive the flowering process. This will cost you yield if left unchecked..

Stop adding nutrients until you figure this out.

Do you have anything to test pH with? Do you have a Hydro store nearby?

i have one of those cheapo color coded drops and its reading ph7
this started about 2 weeks ago and it looked to be spreading slowly, ill take a pic under better light and post in a few mins
the leafs have splochy spots on em that are brownish and dryed out

im having some trouble uploading the pics, ill try again later
i thought id also mention that this problem seems to be contained to one plant, they both are treated equally

Color-based tests are good for detecting bad swings in pH. If your test is reading 7.0, you're probably okay there.

A couple of pH testing tips:

1. Rinse your testing container with distilled water first -- 3X is ideal; shake with the cap on to remove all contaminants from the vessel and the cap.

2. Rinse again with the soil runoff that you're going to test -- these two steps assure that you don't contaminate your test with residues from the containers or past tests. These steps are critical to getting a good reading.

If you've done these things, great..If not, you may want to repeat your test using these tips, just to be sure that's not your problem.

ok, so my camera was acting up, turns out i needed to re install the cameras firmwear, lol
got my cam working so when the lights turn on ill snap some better photoes
thanks Kriegs for the tip, i rinse it thoroughly but i just dont rinse with the runoff water, ill try your method but i think my readings are ok
ittl be easier to see what the leaves look like with the flash lights, the hps makes everything red

ok so the problem that i had before i still have but its not as bad and i pruned off some more leaves that had that problem and it seems to have slowed down, although the top leafs on my pants have have yellowing edges, i took some better pics to show you guys, i was looking at slufer and iron
take a look, tell me what you think

bump!
anybody??

Yo ganja, looks like a nute lock out, try this link, it helped me alot, I was having 8.4 ph readings in soilless coco, got it down to 6.0, This link helped me out!! Guide to sick plants!! On this site!! http://www.icmag.com/ic/showthread.php?t=11688

It was very helpful to me, look at everything on the link, its a long one!!!

first thing I notice is very dark green leathery leaves-most likely caused by an overfert of N. seems you may have used too much grow nutes and not enough bloom nutes. I see the begining of a K deficiency but at this stage nothing to do except stop any nutes containing N and increase slightly your bloom nutes

thanks for that link, iv been looking for that one, the one on this site and 2 others i kept finding had the same pics and not very detailed
from the pics im guessing it one of these or a combination of: magnesium, zinc, boron

That light looks to far away and to small for that tall a plants i wuld try to get the light closer to those nuggys

i had originally planed to veg for 45 days and go to flower but i had problems getting my hps so i flowered till over 75 days, oh well, i dont have to much ventilation in that closet and im away for a couple days at a time so thats why i have to move it in big gaps at once
but the problem on the leaf is to do with the deficiency
next time around ill try with cones and do a scrog setup to avoid the light issue

here is an update
i took some nice close-ups of the leafs
they are droopy cuz i under-watered them
look at the yellowing at the edges, all the leafs affected are at the top

i was looking around for a while and couldnt find to many conclusive answers, iv been watering with only water for about a week so im going to water again in 2 days and ill use nutes at 1/2 strength then for the next 2 weeks ill flush em then harvest
i have 18 more days till iv been flowering for 60 days, im expecting them to be ready by then
