Purple leaves

Hello people,
Got a little purple issue see below.

Stain: white widow

Stage: start of week 4 flower

Watering every 2- 3 days mostly every 2 days

Using miracle grow flowering 15-30-15 at half strength. Due to living rural and not having access to stores with better stuff.

Yesterday I found the leaves on the top of the plant turning purple, I read that its possibly p deficiency.
Yesterday was water day so I used my fertilizer and lost my dam ph strips so I just assumed the water was as normal and added a drop of ph up. My water is well water and the ph is normally around 5.9 -6 if I remember correctly.

Today the problem looks the same or slightly worse.

Can anyone confirm this is a p issue.

What course of action would you take?


Cheers!

Don't change a thing. That appears to be natural color. No burnt tips, no curling. Healthy growth.

purple leaves and flowers? Was supposedly Girl Scout cookies......only some if the flowers look like this. Also 3 weeks into flowering and no trichomes or smell at all!, growing outdoor, using dr.earth and black gold in air pots. We have had an unusual amount of rain. What have I done and what can I do to fix.?. Please help!!

although it dose look like what you expect from possible P def
using that fertilizer its highly unlikely

the middle number "30" is the amount of P
the first number is the amount of N and the last number the amount of K

the P is clearly the largest portion of that fertilizer

are the lights on in that pic? can you get a pic with the lights off

are you getting cold temps... is the source water extremely cold?... is the cement floor cold ? do you know or can you check the temp of the soil?
do you have excessive iron in your source water?

High P and K bloom feeds will cause a radish purplish color sometimes.

Hi. I'm not sure if I replied to my pics....I'm using fox farm tiger bloom. Also used some dolomite lime b/c when I tested the soil ph it was around 6.added 1 tbsp Dolomite to 1 gallon water. I use well water and it does get cold. I have also in the beginning used neem oil and bk spray. They were in the ground but so much rain they had to be moved to pots 10 weeks into veg.

Even the flowers are a little purple

that's an interesting issue you've got there

I think you should start your own thread and post the pics over there.. im interested to follow what it is

what size pot, what strain,

add a picture of the entire plant

1 tbs of dolomite wont be enough, maybe a suggestion after you've told us the pot size

I removed a few initially thought to b bud rot

How did you test the soil ph? Soil ph swings as it dries and was Probably ok where was at though the lime isn't hurting.

Watering with cold water can do it. The tiger bloom can. Let your water warm up a day and cut back on the bloom. Mic a little grow formula in. Cannabis still needs N in flower.

I did a dirt sample from 3 different areas. soil was damp. Had so much rain it's always damp

Not sure why I want I can't start a new thread possibly operator error

if the ph is indeed low

I say you need more like 4 oz dolomite to bring it up to 6.5 to 7.0

its showing in what looks like new growth,

im wondering if its a micro nute issue of some type but I don't remember purple being an issue with micros that I can recall

ive grow some strains like Da purps and the flowers where very purple from the start. but not in the fan leaves like that..

picture of the entire plant would help alot

May be genetic. I wouldn't worry if it continues to look healthy.
