Flower week 6 clawing and spotting.

[Craigc1509]

-Problem: I have a Blue Dream That started week 6 of flower today, I have noticed a bit darker shade of green and some clawing over the last couple of days with some spotting on the leaf edges that are about 5 days old, they haven't got much worse, but have probably progressed a bit. I want to say my issue was using the grow part of the trio fertilizer with the bloom as well for too long causing a N excess which has caused the issues. I think the brown spots were from a Potassium deficiency also being that i was still using part of the grow and part of the bloom mix, when I should have been on only bloom nutrients. I have not fed any nutrients in 3 days, Should I skip at least one more feeding?
I am just curious where my issue lies so I can avoid making the same mistake again!
-Medium/grow method: Soil; Fox Farm Ocean Forrest.
-Feed and supplements used: Fox Farm Trio.
-Water source: Clean PHed tap water anywhere from 6.4-6.7.
-Strain and age: Blue Dream
-Climate: 78 degrees during the day and 70 at night.
- Light used: 2-Electric Sky ES300 LEDs
-Additional info: I had similar spots on the leaf edges on a few other plants but not as bad and no clawing on any other plants like this one.

Apologies for the sideways pictures. my ipad does that when i dont have the auto rotate on..

You probably have as much experience or more than I do but I think your problem may be OF. I'm having a lot of trouble right now and I believe it's in large part from OF. It's just too hot to feed much which makes it very difficult to get a handle on a nutrient mix. I know some will say they have used Ocean Forest with good results but I will never use it again. I think you're looking good though and as far along as you are you should be fine. Have you checked your runoff ppm? Slurry test for soil pH?

Are you using just the tiger bloom and big bloom?

-- I think you called it mate, it's N-tox', often a cumulative thing, not just an overdose from one feeding,.. plants store N in large amounts, but only can handle so much...
Stay with Tiger only, use the Big Bloom (good stuff, but not really what it says it is, look at the NPK#'s.... in the decimal range, beyond weak as a fertilizer)...
Looks like K defc. to me as well, probably will halt with some Bloom nutes use,.. You can also try skipping the Tiger for a round or 3, and use a no N bloom booster to cut out the N for a bit, and boost PK...... GH KoolBloom 0-10-10 comes to mind, but there are others....
Are you checking pH going in? And as always, in-pot pH is something to not be ignorant of, that's the [HASHTAG]#1[/HASHTAG] ass-biter I see in here! To check that, look into getting a soil pH probe for direct measurement, none of this run-off crap which is dubious at best.... Accurate 8 is a good one, or a alternate brand equivalent (same probe, less$, different brand name, but same Chinese factory made!)....
