Well im not sure WTF is wrong, it has those brown spots deveoping and other then that is the best plant i have ever grown. I havnt grown very many plants and all have had thier own problems but with this one I want it to go GOOD I want it to become a momma but im not to sure if it would be a good idea unless i can get this problem solved. Oh Btw it is 15 days old in the pics.
I would love any help you guys could give me.
Well it would help if you told us what that soil is, what you are feeding them, and what their environment is like.
But it looks to me like you have a potassium problem. Check the runoff pH of your soil and tell us what kind of dirt it is.
When you post up asking for questions on issues like this, help us out by providing as much information about it as possible.
For starters... I need to know what soil you are using and the pH of your water source. It appears as if you have some kind of soil that isn't a very good choice to grow MJ in (looks way too woody). Anyways, when I look at "the Bible", the only deficiencies that you may be running into is an early P or Mn deficiency, but I'm not sure on that one bit. You could also have nute lock out. If that is the case, you will start to see more than just some spots on your leaves, so you'll know if that is it.
I'm willing to bet that getting some quality soil and a pH meter would be your best bet. Best of luck.
the plant has defencies, potassium is most evident, the brown necrotic areas look like burn
I agree the soil is poor, most of these low end bag soils that are barky seem to have an excess of ferts pre-added to compensate for the low quality or lack of soils and maybe burning the plant or Have you recently fertilized this plant?
additionally , although difficult to see in the photos , the new growth seems to be twisted & distorted, I would do a soil runoff test to rule out PH issues
complete a soil runoff PH test.......
with PH corrected water (6.5-6.8PH for soil ) pour enough water in the pots so the water runs out the bottom of the pot ...collect & test the PH of this runoff water....post both the watering going in the pots and the runoff ph
looks exactly like what my plants had
rust looking marks
my room was to hot and the lights where to close, i changed to distilled water(ionised)
problem went away
what temp lights, etc and water you use and fert?
i also improved the ventilation, problem has vanished
plus the soil looks bargain bucket stuff
the soil looks about the same as my favorite soil ,'Whitney Farms Premium Potting Soil' ... as for the spotting : Revised: The Complete Guide To Sick Plants,pH and Pest Troubles - PlanetGanja.com ... :smokin:Quote:

Heh, upinsmoke you need help? well reply! So we can help! def a "K" def, maybe a Ph thing? need input m8. Looks like coco is your medium? In that case I'm out. Never grown in that yet! Also try some Cal/Mg with next feed. What nutes? Need more info!
Wow sorry i havnt been on latly but thanks for all the replies, Ok to answer some of the questions, i do not know the ph :-( i havnt got a tester yet, the soil is crapy but its the only think in this god forsakin town it has nutes in it and i havnt been feeding it anything except super thrive its under a 26w cfl now it was only under a 7w in pictures, im using normal tap water ummm i wish i had more info oh ya the only vent i have is a computer fan proped in the door
I know miracle grow soil when I see it. I don't have a problem with it. It has issues but alot of them do. I believe you are overwatering. mg soil holds moisture for awhile. you need a penetrating moisture tester. $5 or $6 let that soil get dry, then give it a good watering. at your plants size I would say 4-5 days between waterings, but get that meter. Are the tips folding down? turning black? necrosis and drying? plus the rust spots and occasional weird curling of the leaves. all good signs of overwatering.
i use the drops and vile for testing the ph very cheap and accurate
i thought distilled was ok? anyway i use tap water now left to stand for 3 days
