pic 1 - nut burnt?
pic 2 - outer tips of leaves curling inwards? whats causing this?
pic 3 - any ideas?

cheers

hey buddy, if your asking for help you need to give as much info as possible. Your soil mix, your ph, lighting, what your doing.

I could ask why is my car constantly stalling? who knows, maybe its battery voltage, fuel mitxture etc.

Give us as much info as you can and hopefully we can figure it out.

I think your first plant is going nute def, and your 3rd is overwatered. but thats a harsh guess.

Here are the details:

400w MH 24/0 in a 4x4x7
4-in inline exhaust fan at ceiling
oscilating fan
humidifer to keep humidity between 55-65
3 soda bottles for co2 (yeast/sugar)
regular tap water using ph down to hit a PH of 6.8-ish
temp is usually 72-80
miracle grow potting soil (high nitrogen content)
all purpose fert (feed every week or so)
I water once a day or every other day (2 gallon pots with pond rocks at bottom for extra drainage)

plants are currently into their sixth week of life

you want to water 1st or twice A WEEK. miracle grow is bad, next time dont use it use schultz. all purpose fert? what 20-20-20? every week is too often. you want to feed one week on one week off. you cant feed everyweek. how much are you feeding?

dude, my plants curled just like that when they were younger. Turns out I had the light too close. I had it at about 14 inches and was told to raise it to 18 and let them grow closer to the light. The curling stopped and all is well. I was using a 400 mh as well.

I've only fed them twice since transplating into their pots, all purpose fert 1 teaspoon / gallon. I just measured their distance from light and its 16 inches. Doesn't make too much sense =/ Also, what kind of yeild can i expect? how many plants per pound? is it different based on how long they veg out for? Thanks.

Looks like over watering, as chronic says--- once a week is more likely adequate for plants that size in two gallons....only water when droop is imminent (if you can, cannabis really LOVES a wet and dry cycle esp. when vegging.)
Consider transplanting into soil with lots of added perlite[FONT=&quot]!

1 - No, Nitrogen deficiency
2 - Heat,either get ventilation or move the light higher
3 - Under or overwatering

These are the probs, the causes for this can be many...specially watering with pH 6.8 using MG soil....that pH should be higher cause MG soil is extremely accidic..

I don't think it could be nitrogen def. cause the miracle grow soil had a high concentration (24% or something) and is supposed to release over time-plus ive fed them all purpose (24-12-12 or something) twice already in the last 3 weeks (half dose). I moved the light up 3 inches to reduce the heat problem, maybe more depending on development. I think I need to let them go through a few days of a drought. Also, do you guys know about the yeast in the co2 mix poses any dangers (i.e. if the bottle overflowed and some got into the growroom). Thanks guys, always.

cheers

ps if it were legal to mail pot id send you each samples of the finished product

it takes a lot to grow a pound. theres some people with amazing plants on here and they say they got 2 oz per plant. thats well actually thats only 8 plants. i have 60 going and i still feel like ill never see a dried pound. actually i cant wait to see how much i can grow at one harvest.
