Mine did same thing @Hellraiser said it was probably just genetics and some others said it might be a phosphorus deficiency

Never did find out for sure but I trust hellraiser and the plant seems fine otherwise

Are you adding any other nutrients other than cal mag? What soil are you using?

Cal mag help but does not have everything a main nutrient line does.

Plants usually Use up all the nutrients from the soil in 4-6 weeks. If you’re not replacing them the plants are hungry.

That being said purple is usually genetics. The purple can be brought on a little more by having a larger swing in daytime temps and night time temps. I believe upwards of 15 degree temp swings.

Looking good though!

I added some big bud for week 3-5 as well.
Soil was a home mixture. I have used this before with success.

Regardless of wether this is a P deficiency or not, I recommend a good bloom fertilizer. There are organic and synthetics available depending on your preference.

P deficiency: The older leaves will be the first to show signs of a lack of phosphorus – especially leaves located near the bottom of the plant. The symptoms will begin there and will move upwards. The affected leaves will turn a darker green, then will show purple and blue colors.

Yeah I’m betting yours is like mine, in that other than the topmost leaves around buds turning purple, you don’t have any of the other signs of p deficiency

Looks normal. Just genetics and cooler night tome temps. One of my last Gorilla Glues was all purple.

Not a Cal-mag deficiency. So I wouldn’t increase the dosage. :+1:
