Nutrient burn/nitrogen toxicity?
Tubington9
started grow question 4y 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?

Yellowing, burnt tips and edges
Hello fellow growers I noticed this happening rapidly after I top dressed. What kind of deficiency is this? Is this nutrient burn as well as a deficiency? Solely a Ph problem?. So far I’ve come up with maybe potassium deficiency and improper Ph when watering? Please help

Burnt tips
My leaf tips are clearly burnt. But not curling up? I thought it was nute burn but I also read lack of potassium can burn the tips. What do y’all think?

I am having issues late in flower. Curling leaves at the top and some brown spots. Please see photos marked #1 and #2. Last week I let her dry out too much (coco), so runoff EC eas very high. Have been keeping runoff below 1.1EC

Light green leaves in color and burnt tips. Some leaves have brown spots.
Hi guys, can you please help me diagnose the issue. The plants are in BioBizz All-Mix soil. Treated with Bio Grow, Bio Bloom and Top Max from BioBizz. Also BioBizz Cal-Mag in the past week and 1ml of B52 (twice). A week ago I flushed and initially they were looking good.

What do these yellow markings on the leave tips mean?
What do these yellow tips on the leaves mean? Are my lights to close? Looks like light burn to me and have adjusted the lights up 10cm for now. Still wanted to make sure since I thought they need more lights during flower. Thanks heaps

Twisted, yellow/brown tips.
Hi, My plant has shown signs of a nutrient excess throughout its complete cycle. It keeps to the tips of younger the leaves that have a tiny twist in the end. I don't think it's the light as it also affects leaves in the lower canopy. I keep on flushing but nothing changes.

Discolored, burnt and curled up tips on higher leaves
Several symptoms, always on tips of higher leaves : they are discolored/burnt or burnt/curled up. LED @40cm (deemed 70% of 300W) and I just gave them the 2nd flowering feeding, 4 days after first one (pots were very light). I was planing to start compost tea... What should I do ?
