You have nute burn. Test runoff and flush if runoff is hot.

Please look at last picture - there is an area of crispy brown on the lowest leaves of the Red Diesel. I'm thinking it's a little bit of light burn, but am not sure. Any thoughts from any of the experts?

Leaves burn
Hi! Is this nutes burn? Damage is on the upper/middle part of the canopy on very few leaves, but many more have black tips. I’m puzzled because during veg I was feeding the plant higher ppm than now and never had a problem!

problems in DWC. I am using TA nutrients (Lucas formula). Running EC 1.8 and pH 5.8. One of my plants look good but the other plant shows lots of problems. RH is 55%, Temp 25-26C. PPFS is 450μmol/m²/s on average. Any idea how to fix it? Dilute the nutrients? Ideas welcome

Yellow leaf edges
I have a couple plants that are about 5 weeks old, and one has started getting yellow edges around the leaves. I feed them with worm tea, kelp, and calmag every other week, but it's a light dose so I think this is a deficiency and not a toxicity.

Leaf burnt edges
One leaf has burnt edges and is a little different looking, than the other leaves. Is this some kind of nutrient burn? I am using a light mix soil, and have not fed the plant with additional nutrients, except for a little root stimulant (half of recommenced dosage).

Leaves yellowing and burning mid flower
Air exchange, pH, nutes, and water should be good. Could my 230 watt on 100% be too much for her? Does she need more humidity? What causes crispy leaves?

Deficiency?
OK so my plants are in week 6 to 7 of flower. I'm seeing what I thought was a potassium deficiency. The nutrient line that I am using is Remo Nutrients. I added an extra bit of Astro Flower (which has the most amount of "K" in it) to the last couple of watering top ups. DWC.
