Burnt leaves? Nuts burn or something else?
Burmeseanswered grow question 3 years ago
Hey friend, When I look into your diary, I see alot of problems there.First I see curling leaves , may be caused due to over watering or nitrogen toxicity.To fix this, let the soil dry about half to one inch down from top.You have already switched to flowering circle.So stop or reduce feeding nitrogen rich fertilizer.Another thing is burn tips.They could be from nute burn due to excess of nutrient.Soil don’t need much nutrient.You should reduce your dosage strength.I hope you are not using folior spray fertilizer.Cause they could cause burn tips easily.Last thing is I found out is some brown and dry crispy leaves at the bottom.They seem to be Cal-Mag deficiency to me.So add more Cal-Mag.Remember always adjust your water pH around 6.5 whenever you water.In this way you can get rid of those in no time.Happy growing.. ✌️

Thanks for the answers guys, I originally thought I had burn so flushed my soils and then Realised I actually had a calmag issue. Have been feeding some trace elements and a magnesium supplement. I have stopped feeding growth nutes for over a week now and have only given one lot of bloom nutes but have since stopped and have only been feeding water. Do I feed the calcium and magnesium supplements every water or do I do it every couple? I haven’t got a water ph tester but is definitely something I need to get going forward. Hopefully now just feeding water for a week it will flush out the nitrogen so I can start some half rate bloom bites next week.
Thanks

Dark green leaves and downward curling- almost definitely N toxicity. Make sure you are checking the EC in and out (runoff).
Hard to really tell much else without your nutes being posted but I'm guessing this is what happened: you saw leaves at the bottom yellowing and after some research figured that you didn't have enough Nitrogen so you increased your N. Unfortunately, what was actually causing the yellowing was a calmag problem, so you ended up giving her nitrogen toxicity.
Bring down the N and add some calmag. This is the best advice I can give with the information provided.

Spotted crisp leavesWhat's up with these leaves? They've all been spotting up, crisp edges and tips curl. I keep flushing them and it helps. I feed them 1 tsp calmag to each gallon and often the mixture gets diluted as much as half. PH water was 6.2 but soil 4.5. 15" from 70% light.

Leaf issues with 3 Pineapple Express Autos - is it burn or deficiency?All 3 plants are having issues to the lower leaves. They are dried and brown blotches, brown edges of the leaves, leaves drooping off and curling down and brown. They switched to Canna Terra Flora two weeks ago - is this a over feed or deficiency?

Harvesting a struggling plant or just letting it fightCan she be saved or just flush her and harvest what I can? She doesn't appear to be happy. Has some CBD genetics so the lack of trichomes don't worry me.
Rest of my garden is fading as well. Flushed em last feeding and they didn't seem to like it.

Burnt looking seedlingWhat's going on with my #2 seedling? I thought it could be light burn and raised my light by 4" but the odd coloration on the tips has gotten worse 18hr later. It also doesn't seem to be drinking whats in the coco yet so I'm cautious about feeding.
