I know the pics a bit blurred but if you zoom in you can see the spots, the other pics is one i got of off web which looked very similar
Iv googled it and all i got was ' septona' ? Or some sort of N defect, and it says the spots start at the bottom of the plant, but these are from the top,,

Its in soil and there only on a few leaves. Its in week 5 flower,
But i did give it abit of liquid seaweed ( someone said it makes the buds denser?)
Ok thanks
 
very blurry picture, try seeing if it matches upto any of the pics below

looks like mites. did u look at the bottom to the leaf. if no bugs there or in the spoil then check this.

Marijuana Diseases – Leaf Septoria – Yellow Leaf Spot
Yellow leaf spot, as you might expect, produces yellow spots on
the leaves of your cannabis plants. It is a fungal disease that
mostly shows up on outdoor marijuana plants that have been
exposed to warmth and rain simultaneously. Spots will start to
appear on lower leaves first, before working their way upward.
In severe cases, an entire leaf might turn yellow and then start
to crumble away. For the most part, only leaves and occasionally stems will be affected and
your crop as a whole won’t be endangered because of yellow leaf spot.
Still, yellow leaf spot can decrease yield and it’s important to avoid it at all costs. Preventing
yellow leaf spot is all a matter of using sterile gardening practices. For instance, you should
always till the ground thoroughly and maybe even use a fungicide in the compost so that
yellow leaf spot is dissuaded. If that doesn’t work and you still get yellow leaf spot on your
plants, then there is a way to beat it using a mixture of baking soda and other practices.

Hey folks, so here is info on diagnosing your ill plant and my guide on plant body language too! hope it helps!

[color=\red\]Nutrient Disorder Problem Solver

To use the Problem-Solver, simply start at #1 below. When you think you've found the problem, read the Nutrients section to learn more about it.

Diagnose carefully before making major changes.

1) If the problem affects only the bottom or middle of the plant go to #2.
cool.png
If it affects only the top of the plant or the growing tips, skip to #10. If the problem seems to affect the entire plant equally, skip to #6.

2) Leaves are a uniform yellow or light green; leaves die & drop; growth is slow. Leaf margins are not curled-up noticeably. >> Nitrogen(N) deficiency.
cool.png
If not, go to #3.

3) Margins of the leaves are turned up, and the tips may be twisted. Leaves are yellowing (and may turn brown), but the veins remain somewhat green. >> Magnesium (Mg) deficiency.
cool.png
If not, go to #4.

4) Leaves are browning or yellowing. Yellow, brown, or necrotic (dead) patches, especially around the edges of the leaf, which may be curled. Plant may be too tall. >> Potassium (K) deficiency.
cool.png
If not, keep reading.

5) Leaves are dark green or red/purple. Stems and petioles may have purple & red on them. Leaves may turn yellow or curl under. Leaf may drop easily. Growth may be slow and leaves may be small. >> Phosphorus(P) deficiency.
cool.png
If not, go to #6.

6) Tips of leaves are yellow, brown, or dead. Plant otherwise looks healthy & green. Stems may be soft >> Over-fertilization (especially N), over-watering, damaged roots, or insufficient soil aeration (use more sand or perlite. Occasionally due to not enough N, P, or K.
cool.png
If not, go to #7.
7) Leaves are curled under like a ram's horn, and are dark green, gray, brown, or gold. >> Over-fertilization (too much N).
cool.png
If not, go to #8.

8) The plant is wilted, even though the soil is moist. >> Over-fertilization, soggy soil, damaged roots, disease; copper deficiency (very unlikely).
cool.png
If not, go to #9.

9) Plants won't flower, even though they get 12 hours of darkness for over 2 weeks. >> The night period is not completely dark. Too much nitrogen. Too much pruning or cloning.
cool.png
If not, go to #10...

10) Leaves are yellow or white, but the veins are mostly green. >> Iron (Fe) deficiency.
cool.png
If not, go to #11.

11) Leaves are light green or yellow beginning at the base, while the leaf margins remain green. Necrotic spots may be between veins. Leaves are not twisted. >> Manganese (Mn) deficiency.
cool.png
If not, #12.

12) Leaves are twisted. Otherwise, pretty much like #11. >> Zinc (Zn) deficiency.
cool.png
If not, #13

13) Leaves twist, then turn brown or die. >> The lights are too close to the plant. Rarely, a Calcium (Ca) or Boron (

deficiency.

If not. You may just have a weak plant.
