this is a easy ryder about 6 weeks old. I alternate feeding between a gallon mixed w/ sea grow nutes 4-26-26 and a gallon mixed w/ molasses and cal/mag. the last watering it received was 2 days ago with molasses and cal/mag. Some leave are begining, as you can see, to turn yellow with brown spot and some with leave tips curled UP. This has come on way to fast for me to believe it jsut a maturing plants with leaving turning yellow. its not jsut lower level leave either some up close towards the top as well. HELP!
 
being a lower leaf don't worry about it at 6 weeks in, it's prolly a lack of light so the plant is moving those nutes from the leaf up higher and will drop that one soon.
 
Have you been feeding that the whole time? 4-26-26 is for flowering not vegging.

#1 question that the answer should be posted with your initial post/question> What is your ph in and out?

That leaf is higher up, Riz.
 
my ph meter broke. As of about 2 weeks ago the ph was at 6.7. I didnt start feeding the nutes til 3 weeks or so after sex. I know i need to get a new ph meter asap. I jsut didnt know if anyone could say from the pic wether it was nute burn and def.
 
Im not good with identifing problems but i can tell you from running the 4-26-26 by its self your gonna have low (N) and very early yellowing and leaf die off
 
for veg you always want the N to be larger than the last two numbers and in flower you wasnt the P K to be larger, i would also guess if you dont have a PH meter, and if it broke it might not of been working right,also you might think about getting a tds so you can watch your PPM's . and JM sent me this it might help some

sniper what do you recommend to help with the low N. I'm confused b/c I always assumed flowering periods required little N. I use cal/mag and molasses also so what else would I need?
 
i use the seagrow 16-16-16 till week 7 then flip to the 4-26-26 for a 10 week strain
