I'm ok letting them grow out (as tough as that is for all of us) - but I am worried about the Powdery Mold. Right now on the base of the Stem only.

thanks to all - I'll let her be - I'll flush for the mold issue and let her grow - I'll be back with pics and issues if any more arise.

agreed- check PH but I'd bet on N def. I use FoxFarm Grow Big. Also, recently read that sex is determined when seed is fertilized- not env factors - which can contribute only slightly. I usually grow 3 - 4 per strain, increasing the odds of getting at least one F to 4/5

How would I know if the buds have PM? - short of seeing the white mold on them - which right now I don't.

I also was giving N in the nutes - but will stop. I'll do a complete flush tonight and leave her for a few days and see - thanks

My first grow of Northern Lights (indoors) 8 weeks grow (2 seedling + 6 veg) to 24". Flowering - starting 5th week (from start of 12/12 cycle). 400W HPS in 4 x 4 grow box (with fan and heater). Using FF nutes Not sure how much longer. Lots of "frosting" on leaves and buds. web says 7 -...

btw - if you have 3 nodes you are not seedling anymore but are most likely in vegetative state. have u started nutes? Pics help ;-)

if the other (new) leaves are fine and show no bad signs then don't worry about the cotlydons (oval leaves) Temp s/b in around 75 f

Around week 5-6 you will see the beginning of pre-flowering signs. Look for posts on pre-flowering and go from there.

Seeds: As said, you are not guaranteed a female even with feminized seeds. I have started to growing 3 or 4 of a strain at one time, thus massively increasing the odds of a female. If I remember my statistics, with 4 seeds there are 5 possible outcomes with 4 seeds: 1. 4 Males 2. 4 Females 3. 1...

I'm a new grower and this is my first exposure to PM (see pic) Background: Moved flowering plant from closet to garage (4x4 grow tent). Temp diffs (night = low 50s -> day = high 70s) and increased RH (as high as 60%) I think caused PM to take hold. I have: 1. Added a heater to keep temps...

Male for sure- the little clumps are the give away Female has a single fig shaped pod with two small white hairs coming out. UNless you plan to retain pollen and pollinate a female for seeds - say good bye and let them go. It's hard I know - been there.

i agree - my bad I misread your post. Yes, if you're seeing yellow two weeks into flower (is that 2 weeks since you went to 12/12 or 2 weeks since the Primordia changed (went from making leaves to making buds). Also, is it all leaves? or just older ones? Are newer ones discolored? I would...

yellowing is normal and to be expected as the nitrogen the shade leaves is use dup bny the plant during flowering. I usually pluck them off when they are ready to go. I've read that adding N to the nutes during flowering (alleviate the yellowing) can actually delay maturation and harvest.

I will test again today and see -= thanks

temp runs in the high 70's there is an oscillating fan on all day on low.

Mistype - meant First Grow Using FF BB & TB (per label), giving about 1/2 gal water and the water is absorbed from overflow tray rapidly and soil is dry by the afternoon. At first i thought it's underwatering - now thinking too strong nutes. pH in 6.5 - 7 range. suggestions?

Well, Depending in how involved you want to get- start measuring soil moisture, consider watering with a fertilizer and read, dude, read - like we all do. If they're outside the you can't control light... Also - definitely consider the Security issues...

understood - and yet, if one grows and gets a bunch of males first time it's pretty depressing

Good light - I use HID MH about 12 - 18 " from plant 18/6 (or 14/10 for fems, I've heard). Not sure what "puny' means - mine after 4 weeks are about 7-10 inches tall, showing preflower signs and are bushy. Depends on strian. Temp, ph, humidity all play a facotr. I use FoxFarm Grow big +...
