Hello all, this is my first post and my 3rd grow but only my first sucessful one....

This is the first time that i have ever encountered this problem and i dont know if its because of the water or what... Ive always used botteled water but it was always zepherhills, this time i bought walmart brand and have encountered a yellowing browning problem....I have now switched to RO filtered water and will see if this helps..

Since this problem, ive done as much research as possible and i have increased ventilation, raised my lighting further away and just today started the babies on some nutes but what if i am wrong.... i need some help trying to find out if this was a simple heat issue or a nitrogen difeciency or possibly more?? i have attached pics too

lighting: 125w ultra compact flourescent
3 weeks into growth

certainly not a expert, but looks like nute burn, maybe your soil is too rich

What kind of soil is that? Mj doesn't like bark and shit. I'm guessing pH issues but could be nute burn or heat stress as well. I would transplant immediately and fill your pots almost full next time.

Agreed. you may have got it in time to survive the transplant. use the best quality soil you can find. there are great recipies on this site.

what soil, what's your pH, what nutes, how often do you water?

i just didnt think the soil would be that rich, i hadnt gave it nutes until this morning and now im worried bc i could be making it worse. going to the store now to get botanicare soil.....small waterings every other day or two

are you allowing the soil to dry between waterings

I always had the same problem. I started growing outside and never ran into a problem except for bugs. You may want to start a grow outside next spring cheaper too.

if i am not mistaken.....those are in plastic cups. never use plastic cups. nute burn is def the case here. looks like they can make it tho, ganj is a damn strong plant....just took a closer look......red drinking cups.....get them out of there. keep the soil, just transplant into bigger. being as how they are in such a small area, the soil has no way to quote breathe u nquote....lol......bigger pots, will def work. plastic holds in chems,depending on the specific material. plastic cups are a cheap plastic.
