Goodvibsstarted grow question 4y ago
Hi all, I have had very slightly yellow tips on this plant for a while. She is mid week week 10.
Two days ago the leaves started to curl and the yellow has spread slightly. Last night I flushed her with PH water and have dimmed the light slightly, anything else I can do 🤙thanks

Quite simply, the yellow tips is burning from feeding too much or too often, or both.
The solution is simple......

Leave your lights at 100%, it is not caused by or is a lighting issue in any way.

Going to disagree with my grommie here... magnesium deficiency is first spotted on lower leaves, not on top... BUT I agree that dimming your lights is going to help ... my thoughts are that this is happening due to heat stress - and you're certainly much too humid for the flowering stage! So try to drop both your temps (70 would be great) and your humidity (it should be about 40% not 60%!). Making sure your getting lots of fresh air to your grow will help as well... You're going to want to fix this so you don't end up with foxtailing, too!
Good luck!

hey there GoodVibs, what you're seeing is magnesium deficiency , reducing the light cycle does help with that, but really you do need to add a calmag supplement to stop the spreading and see the plant recover. Hope this helps growmie ! 🚀

Surplus or deficiency?Can't tell if there's a surplus of nutrients or a shortage of potassium? One plant looks like nitrogen burn and the other two look like theyre maybe a little k deficient. Was thinking of chilling out on the feed on the burnt one and just feeding micro to the other two. Thoughts?

Is the slight yellowing ad curling of these leaves ok or indicative of something?Curling and yellowing of leaves in a few instances, both near the top and bottom of the plant, with no noticeable discoloration on the branches in between.
I'm feeding it 1/4 strength Grow Big (2Cups) and 1/4 strength CalMag (1Cup) when I water every 3rd day. Ph runoff 6.8.

Yellow and fragile leaves 2 weekCouple leaves yellowing and bit curved up. I suggest there can be the options: 1) magnesium deficiency; 2) nitrogen deficiency; 3) Light burn.
For case it is magnesium deficiency I sprayed the leaves with magnesium sulfate (solution - 1g per 1 liter), but it won't help.

White tips at the end. Brown patches. Leaves curling.
I've been feeding it 0.5L Advanced Nutrients Coco Big Buds.
The light was fairly close, at 30cm. I've raised the lights to 60cm.
It was also very humid, so I've opened the air vents .

Leaf problem and purple stemsHi,
I have a problem with my auto.
I have purple stems and problems with the leaves.
The soil contains organic nutrients and mycos sometimes I add flowering boost from royalqueenseeds so I don't think it is P or K problem.
Is it a nitrogen deficiency ?… Show more

Week 2: One of the plants still doesn't look good + other beginner questions :)Second week and one of the plants has weird spots + leaves curled.
Not sure what to do. Do I overwater? Is it some kind of disease or deficiency? No idea.
Also, when should I start feeding the plants?
And how much water do I need at this point? 😥
