I'm pretty sure it's phosphorus deficiency but i think it also resembles cal/mag deficiency but I wanted to make sure.

These girls are 2 weeks old feeding daily on full strength GH week one of trio w/ 5ml calmag and 1/4 tsp of supertrive. @ 600 ppm. Ph test with dropper 5.5-6.5 area.

Growing in coco

Please help me guys

Hey, you should check the ph of the water and soil. Usually tap water is extremely alkaline. Here in montreal it's about 8,5. If you don't have one, buy a ph meter such as this (that's the one I have, it's cheap and it works) http://www.amazon.com/dp/B00Y0NVH8C/ref=twister_B00VRJE3KG?_encoding=UTF8&psc=1

You should get your water ph around 6 to 6,5. I've also had ph problems at the beggining of my first grow and it's critical to have it right. Poor MJ plants really hate alkaline soil.

Thank you for the reply!

I do need to invest in a digi ph meter for more accurate readings. I guess im msking a trip to the hydro-shop tomorrow!

I check my runoff and it comes out pretty close to how its goes in and my ppms decrease by about 200-250 at runoff.
 
If those are your lowest leaves and the problem has not continued onto the upper leaves than I wouldn't worry.

Yeah digital is way more accurate than strips. I wish you good luck in your grow. Is it your first one?

No, not the first just havent run into this before. I have grown this plant (strawberry cough) from seed a couple times. And im definitely getting a digi one tomorrow.

They are the lower(1 finger) and first node(3 finger) leaves. I'll keep a close eye on things and post back for further update.

Thank you also for imput:bigjoint:
 
So I went and bought a nice ph meter and turns out what I thought was 6.0 was actually 7.0 :wall:

I adjusted my ph and feed them. I guess we'll see
 
I know, should hopefully be taking cuttings in a week or so and sex these ladies.

I'm curious now though if the solution in the gh dropper goes bad over time or something... cause I just flowered this same strain a few months ago and not once had any issue with it or ph.:?:
