Just curious if this looks like early signs of Nute burn to you guys. Im running Maxibloom only at recommend amount of 1tsp per gallon (approx 4.5 grams) I guess my question is, can you still burn plants with low PPM's? I never go over 1000ppm and my plants typically always look great. I just flushed these 3 days ago and kicked back in with nutes at 900ppm. Im noticing burnt tips on almost all plants. Which concerns me because I just kicked in KoolBloom today for day 40. 4tsp for 5 gallons and topped off my rez. Thoughts?
