Burnt leaves? Nuts burn or something else?
Burmeseanswered grow question 4 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.

Browning of leaves, heat burn or pests?Plants are showing signs of browning, and other weirds leaf markings, kind of grey-ish not too pronounced. It's been very hot and sunny here for 5 days, temps reaching above 37°. I left them in the sun during this period, is it heat stress? Otherwise growing nicely.Leaves. Edges burnt

Heat or deficiency? Or something else?I'm noticing some sort of deficiency or toxicity. I need help on figuring it out. I water with distilled water, cal mag, and 1/2 strength bloom boosters. Ph @ 6.5.
Could it be heat? It gets a little over 80 F. I have AC running, It's still cooler than outside in the sun thoughWeek 6

Is this due to the sun and hot weather?Some parts of some leaves are looking like they're burnt or something.
Is this due to the sun? Or do I have another problem?
It has been extremely hot last week (around 35 degrees all week). And the plant has been in direct sunlight (I've moved it into the shade yesterday)4 years ago

Sick leaves, good budsSome leaves look sick. (Last photos at 8 weeks) Is this an overdose? Do I need to fix this? From fertilizers, I apply only ripen. I plan to give it 2-3 times and then flush and harvest.
I know that ripen helps to end life and makes the leaves turn yellow, but not so!4 years ago
