2 days into flower, i notice these ugly brown spots on some leaves including newer growth, plus some older leaves yellowing and dying off, could it be a cal-mag deficiency or is it something else? using fox farm nutes and soil

i always thought bloom nutes were added as soon as you flip the switch to 12/12, but recently i've read some posts that suggest you add it as soon as sex shows. surely this can't be right? why would you add tiger bloom for example (i am using the fox farm tri-pack) when your plants are still in...

i was running out of vertical space in my tent and i really hate having string everywhere so i just tied the branches together in a circular fashion. what do you guys think? is this okay? does she look ready to be flowered? i'm a bit concerned her stems are so thin... I never had a plant...

Can you bury the stem of a plant with no adverse effects? Cause I have a plant that has grown too rapidly and the rest are playing catch up. I was thinking of burying the stem about a half a foot or more when I transplant next week, just so the canopy will be pretty even with the other girls who...

heres 4 ladies, 2 aks and 2 white widows... approximately 72 days from seed. they are about 26" tall from the bottom stem to the canopy. i did some LST training and fimm'd there tops many times...also cut the bottom third of each plant completely since i don't want fluffy buds. Thinking of...

i have 12 clones sitting under this 42 watt cfl... they are in peat pellets as you can see, inside some plastic cups. i am a bit worried there is no condensation after they have been sitting there over an hour though. does this mean it is probably not humid enough inside and they will likely not...

What do you guys think of these cooltube reflectors? Do they create hotspots?

I am building a small veg cabinet for my clones. It's about 1.5x1.5x3 ft. I am using 42 watt cfls with y-splitters connected to a power strip. These cfls are pretty heavy but I think i can hold them with zip ties. Problem is I want to hang them horizontally on the side because I heard they give...

so i have a severely rootbound plant in a 1 gallon pot. i am planning to transplant in a 2 gallon next watering, but i just want to know what is the recommended method of dealing with the rootball. should i break it up or just leave it alone? i've seen people who recommend gently cutting it with...

Hey guys this question is mainly for those who grow in soil under scrog, but anyone can answer if they have an idea.. i want to know how to get rid of all that water in the last 2 weeks of flowering when you have to flush. if i remember correctly it is recommend you flush 3x the capacity of...

i am a bit puzzled about how to do this. i understand air exchange is important for healthy plants. i run a 400cfm inline 24/7 at low-speed to do it. this has probably cost me a little more in electricity but i don't care if it gets the job done. i'm wondering if other people do the same with a...

I am a little confused about the ratings listed for carbon filters on websites. My CAN filter has something called a "Maximum Exhaust CFM" which is 200cfm, and something called a "Max Recirculating/Scrubbing CFM" which is 400cfm. I have a 6" Inline Fan hooked up to a speed controller that's...

well i lucked out and 5 of my 6 plants turned out to be ladies. 2 ak's and 3 white widows. problem is that is too many for my personal grow. i would be happy with just 2 nice females, one of each strain, keeping them as mothers and taking clones off them. my question is what sort of...

I will wait a while just to be sure, but what do you guys think. Male or Female? Sorry for the quality of the pix

Why do these fans have such useless mounting brackets? Anyone who owns one of these fans please tell me how you hung them safely. The mounting brackets fit very loose on my 6" fan and make me uncomfortable with using them to hang over my plants. It's like they give you screws that are too short...

by chance i just happened to be looking out my window and spotted a black SUV with two guys in it (not parked, but coming out of an alley). i'm not good at making out models but it looked like one of those big american cars, maybe a Ford. anyways the scary part is it drove a full circle around...

this is a small annoyance i have with soil grows. my pots have lots of holes at the bottom, so whenever the soil is relatively dry, a little falls out the bottom when i move them around. how do i prevent this from happening? i was thinking of putting some netting, the kind on screen doors used...

thx they are gone

this is a 3 week old white widow growing in 8oz cup of FF ocean forest, its extremely droopy and stunted, leaves are papery dry and "claw-like". i don't know whats wrong with it but i'm using t5s so temperature is fine (mid 70s), humidity is in the 35-40 range. i thought i gave it too many nutes...

this is a really dumb question folks but exactly how do you arrange a cooltube, inline fan, and carbon filter together in, say, a 4x6 closet? i know where to exhaust the hot air (through a hole in the ceiling of said closet) and where to pull in the fresh air (through a couple small holes in the...
