I just got this Afghan strain from a buddy and by week 2 it started to get a lil brown on all the new growth. Now i'm in week 2 of flower and now they've gotten worst. I'm doing dwc, ph 5.6, supernatural bloom mix. I've seen a lot of pest and mildew but never seen anything like this before...

Hi, I'm in the 3rd week of veg and all the new growth is starting to die off or turning brownish. I'm doing dwc, 900ppm ph 5.8, strain is an Afghan crossed. It's starting from the bottom and moving it's way up. the fan leaves are even curling up really bad. Here's some pictures. Thanks in advance!

i'm in my 4th week of flower, doing dwc, 700-800ppm, ph 5.4-6.0, strain sour grapes. seems like the deficiency always starts about the 2nd week of flower. i'm using ro water but i add about 150ppm of ca-mag back in. it's a new strain i just started so it's something specific with this strain...

everything was pretty until i added gnatrol, 100ppm of GH micro and 400ppm of supernatural bloom. then 2 days later i get this deficiency. anyone know what this could be? thanks

i just got done transplanting these ladies into my waterfarm buckets and now they're stressed. i just topped them before going in so i'm thinking it might be that. i never remember a plant stressing out bad like this from topping tho. kind of look like over watering but these bitches are 24" and...

is it normal for pure RO water nothing mixed in it and when it sits for 4-6 days non aerated it starts to create a cloudy film on top of the water? i have nothing inside the rez or mixed any nutes but still gets this weird slimy film on the top of the water. what the heck is it?

I've been veggin for almost a month now and I can't get these bastards to take off. I had problems with my previous plants not growing as fast due to either aphids or gnats. So I tore down everything and started over with a new strain and it's still growing slow for me. Right now I got Kush in...

what do you guys think? i'm thinking it might be magnesium deficiency? if so, what's the best method to fix it? i'm doing hydro rdwc. Thanks guys

I got gdp in rdwc and on my 3rd of veg. they dont seem to be looking as green as i want it to be. my water temp is around 68-69, ppm 690, ph is 5.2-58. feeding them ro water with gh 3 part mix. so it looks like it's light green where the viens are on the leaf. i hope these pic will be enough for...

i'm having problems with my roots dying off. i know when using grodan cubes you can't keep them saturated at all the times or else it pretty much suffocate the roots. so i don't keep them wet at all besides the initial soak and if it gets too dry i top feed it. so it's been almost 3 weeks now...

so i've been having problems with root rot. i was told to use both sm90 and dm zone. i've been reading a lot and it's either u use sm 90 or dm zone and not together correct? it's been frustrating cuz i have a chiller and keep my water temp around 66-69 and still getting this root rot crap. is it...

sup guys, i was curious if you were to get raided and all you have is growing equipment. can the cops charge you with anything? does it need to be dismantle and put to the side or can u just leave it up but obviously have no plants? thanks!

hey guys, i haven't done GDPs in awhile and decided to go back to them. well it's been 2 weeks in veg and they're starting to look rough. i'm doing dwc and my ppm started at 350 and the 2nd week i bumped it up to 550. for some reason my plants are stunned and the roots stopped growing. the roots...

so i got half of these strawberry cough from a friend but it was in 12oz cup of soil. i only do hydro so i had to transfer it to these grodan cubes and it's been almost 2 weeks and i'm seeing very slow root growth and new growth. i know they're stressed but does it usually take this long? i...

whats the best and quietest fan on the market? thanks in advance!!

i've been seeing a lot of people using this lollipop method. i've never seen it done before but i would like to give this method a try. i just don't know how much to de-leaf and when to de-leaf. if someone can explain in depth on how to lollipop that'll be great. thanks in advance!!!

i've been vegging for almost a month now and they look like they're not growing anymore. i'm doing dwc with 1k mh and using ro water. so i just started to use AN a&b with liquid karma and that's y my roots are brown. well the LK left all this gunk on my roots so i flushed it for a few days and...

i yielded 4.1 with 20 plants under 3600w in bubbler buckets. is that pretty good or should i be able to yield 5lbs with that much wattage? i just feel like i should be able to yield 5lbs. i had like 4 or 5 runts out of the 20. maybe my expectation is too high!!! let me know what you guys think!!

so i've been reading a lot of different posts about the plastic in hydro huts releases off gasses that harms the plants. well i'm not using hydro huts but i'm using black and white poly and was wondering if that's safe? thanks...
