55 days into flower and some leaf tips turning purplish, normal? underfed?

[chimei]

55 Days into flower in soil that is being fed every 2 days with half gallon of water and 1/2 Tsp (1/2 Strength) Tiger Bloom, and 1 TB of Big Bloom, PH adjusted to 6.0.

I am not over watering, ever 2nd day the plant is wilting just a bit and the soil is dry.

I just noticed at around Day 49 some of the fan leave tips turning purple, but now more is. (See pics) It does not look burnt anywhere that I can see, is this me NOT feeding them enough? I have never seen this before.

Max room temp is 75, low is 60. 30% Humidity

I am worried because I have at least 10-15 days before this one is done, so if it is a problem I can fix I want to try. I am worried if it goes to all the smaller leaves I will have to chop early.

Thanks for any help!

2 pictures showing purpling that is happening.

Completely normal, you just have color changing strain
Your night temps are low; a lot of times this causes strains to show there color changing genes. normal it takes around 70 to 60 F range to show this..... colder temps on the other hand can slow down your yield and make it smaller; but none the less it's beautiful when you see them like that! Congrats and some very fine healthy looking gals!

I guess I got worried because it seems to be coming on like a deficinency or something. It probably has to do with the fact that I am in late flowering and some of my fan leaves are going south that got me worried. (coupled with the blue)

If I remove the blue coloring from the picture I guess you are right, everything is progressing like normal. (By this time I normally have Fan leaves start to be used up by the plant)

None of my smaller leaves are being used up yet, but some seem to be turning blue also now very gradually (tips first).


Thanks for the information.

I have a strain that stems purple on maturity. I killed one or two treating them for phosphorus def.(lol) It turned out to be my most outstanding pheno. Now this trait I breed into every new cross. This trait is pretty dominant.

This is my first experience with purple so I wanted to make sure before I went and made it worse. I assumed I must have some sort of defeciency. I am just going sit back and see how much of the purple coloring comes out.

you used blue coloring? like food color?

Yep, just a genetic response. Just the plants pulling nutrients from the fan leaves during finish. Some strains show purple when they start using up the phosphorus on the leaves. Normal. May be an indicator to give them a tiny bit bigger dose of Tiger Bloom but not necessary.

Normally phosphorus would be a lighter brown purple; like trees when they response to a colder temp and less light hours there leaves change color, does not mean they have a nutrient related issue; but I would not give them anymore of anything; the plants are perfect.
