N toxicity?

Hi all,

need some help identifying the issue here. I’m not sure whether this is a nitrogen abundance or possibly a potassium deficiency. The fact that the leaves aren’t dark green is what is making me think it’s not N tox. But there is the famous clawing

strain:Bigfoot glue -Hsc
Cycle: 4-5 weeks into flower
Feeding: I have been following FF trio soil feeding schedule to 60% of the what the chart says

I thought I was seeing signs of lock out so I flushed with sledgehammer on 7/30 and I’ve since continue to feed with schedule. I typically water 3 times then feed and repeat. Ph has been 6.3 run off has been within .1. I use RO water and have been using cal mag with feedings . I thought this might be more of a magnesium issue so I added half a teaspoon of epsom salt the the last 3 waterings. I also bumped ph up to 6.8 last 2waterings thinking it would make it more available. Someone help I don’t want this to affect the bud development! Thanks!!!

I would give them some epsom salts (1tsp/gallon) , quit using the tiger bloom and instead up the amount of big bloom.

Thanks so you think it’s a mag deficiency? And why no tiger bloom I know it’s a lot stronger and contains some N but curious on your thought process

I used to use tiger bloom before switching to full organic growing. And from time to time I had issues. I quit using the tb and upped the amount of big bloom. When I started doing g that all of the other issues went away.
the magnesium issues I had while using tiger bloom were set straight with a light foliar spray with epsom and adding it to the water. There could be other issues too.
I don't ph anything anymore but 6.3 seem a little low. I would try to vary the ph more and lift it a little.

And since you are feeding I would feed more often than every fourth watering. They may just be hungry as the discoloration is even across the board. Anyway those are the things I would try.
Good luck friend!

The like green plant makes me think needs some nitrogen in the diet.

I would have been doing some top dressing in their

They look hungry. The claw can happen during a light cycle and go away when lights are out. Look at a high speed video during lights on, they move around quite a bit.
