Mute burn or deficiency?

Thought this was looking like a nitrogen toxicity so flushed plant down to 1,000ppm and about 6.2 ph was at 5.8. Kinda looks like a potassium deficiency as it went farther along. So I fed it fox farms nutes without nitrogen. Just seeing if anyone has any ideas what it could be.

Most likely nutrient burn if you’ve flushed “down” to a PPM of 1,000. It should be maintained at 1,000.

pH problems are common later in flowering when using the FF Trio. Your pH target is 6.5. Most good cannabis soils will revert to a pH of 6.5 with a flush down to 300 to 400 PPM. What soil are you using?

Are you using a “bloom booster”? They can cause problems too.

Those spotty looking leaves make me suspect pests.

Yes, take a quick look under those leaves looking for bugs

Using fox farms happy frog. And would you suggest flushing again but to the lower ppm. Some of the leaves are starting to turn yell that have the burnish spots. I do not see any pests. The only thing I see are little white bugs in the soil(living soil) I also have worms in the soil

My other plants I have. I have only been using phd water at 6.4-6.6 and so far no signs of anything with them that I see

@MidwestGuy @HMGRWN these are what the “burned” leaves are looking like now.
