Yellow tips
ItalyGrowstarted grow question 5 years ago
Dont know why but one of the girls is suffering from stress. I think this is the cause for the yellow tips or do you have a other opinion? I did LTS training every two to three days, maybe therefore?
A other reason could be light burn. But with a distance of 50cm I dont think so

There are several issues that could be contributing to the issue. First, dark green foliage and clawed leaves (tip pointing down) that's over feeding, in this case Nitrogen. Second; 0,4 liters of water per day is too much at this stage. The yellow tips, it is probably due a minor element lockout (again because of over feeding). 5 Gallon of soil does not need feeding yet, wait until the plant consumes the nutrients in the soil and shows the first signs of deficiencies, most probably you will not have to feed more than once or two times in the whole run.

Dark green foliage + some clowing on the leaves = Nitrogen excess , I feel like you could experiment a N excess but it's not the answer to your question.
The fact that the yellowing in not starting from the bottom leaves to spread to the upper leaves makes me think that it is not a primary element ( N P K ) or a secondary element ( Cal / Mag / S ) deficiency , it would have start with the bottom leaves first so I feel like you have a trace elements deficiency , which one ? I'm not specialist enough to tell you that , sorry .
Looks like a K deficiency ( potassium ) but the older leaves would have been afected
It's not a light burn like you said , my Sticky beast started to burn when she was 5 cm away from my mars TSL1000 and even at 10 cm it takes a couple days before the burnt become serious ( and by serious I mean soft , I know what a hps burn can do so this one is a soft one )

What can I do? Leafs starting to turn yellow. First growerYesterday, I noticed some leafs starting to turn yellow and also the tips of the top leafs to be a bit brown. So I watered (nutrition in the desc) and calmag 2 ml, because I thought it might be either lack of PK or cal mg. What else can I do? What about my watering schedule?

Living soil and rain water problemHas using rain water killed my living soil?
Has anyone got experience of using living soil with rain water? Apparently the ppm is too low (just like RO water) for the plant to take in nutrients.
So basically is my living soil now just soil or is the microbial life still there?

Can I use magnesium sulfate foliarly?Hello, this plant is at the beginning of flowering and apparently has a magnesium deficiency, right? Can I use 100% Mag Sulfate from the pharmacy via foliar treatment? I'm using Calmag 2ml/L but it's not having any effect.
I should add Dolomite Limestone to the soil this week.

Yellow lower leavesHello,
This is my first grow and now I'm confronted with the first problem.
The lower leaves on my plants are turning bright and yellow. A few leaves have very small brown spots. Can someone help me and perhaps have an idea as to how I should proceed? Thanks.

Nitrogen deficiency but why?My Critical Auto is more and more wilting and yellowing. Most likely due to nitrogen deficiency. Some have red tips on . PH of soil was normal, how can I make sure that it's not nutrient lock anyway? Should I flush it nonetheless? Feed it more? More info in my diary.
