Tubington9started grow question 4 years ago

I seem to be experiencing nutrient burn and nitrogen toxicity, is this fixed by just flushing with PH’d water for the next couple feedings?

Yellow tips New grow, new leaf colours! I think it could be over feeding, but would like to see peeps opinions if possible. Have stuck to the feeding schedule, but the fabric pots might be making things more complicated somehow?

Small brown spots on leaves This plant is now 6 weeks into flower in a 5gal dwc bucket and after changing the water yesterday these spots started showing up this afternoon but only on a handful of leaves. Am I looking at a deficiency and if so what would be a good remedy or additive?
