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...

so my clones are about 2 wks old and they look like this. there are already roots sticking out of many of them. i am making sure the peat pellets do not go completely dry or get too wet, but stay moist with PH corrected water & superthrive. the humidity in their domes has stayed between 75-90...

yea i should have done that earlier in veg but i waited too long and the top of the canopy you see in the picture is about the lowest i can go. if i pull down most of the branches any lower i'm afraid they will snap, so i'm trying to get everything even at that point (and cutting any lower...

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...

actually they didn't stretch that much.. they used to have a bunch of branches there but I cut off the bottom third of each plant to focus their growth near the tops. If i had a powerful light I probably wouldn't have done that but I'm only using a 400w.

i can't wait that long, in that case i will just try out some super cropping and do some more LST. I am just going to transplant them from a 3 gal to 5 gal container. I hope that will leave enough room for the roots until they finish flowering. I checked underneath the pots and the roots were...

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...

ok but i only have a 400w hps right now so i cant get very good light penetration in that bottom area... you think it was still a bad idea? i forgot to add that my plants are in 3 gal pots, i'm hoping they dont get rootbound before i start flowering in 2-3 weeks. do you guys think i will need...

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 think some people use foam speaker grill material on their windows. that will hide anything you have on your window and still allow you to push/pull air through. its a black foamy type material you buy in squares and cut up to the proper size. any hot air being pushed out your window will be...

thanks so much. i forgot i actually have one of those mini hothouses. i will transfer them from the plastic cups soon. i am a bit worried about the PH since the peat pellets are supposed to lower PH significantly. should the PH of the clone medium be the usual 6 - 6.5 ? also what should the...

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...

same thing, that's why i'm asking. two of my gals had their tops turn lime-green/yellowish...i thought it was a cal-mag deficiency at first but that wouldn't make sense (two others are fine and the last two feedings were plain water)... i'm thinking it was the cooltube creating hotspots and...

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...

i am using the same soil. you are right 9 gallons is too much i think i am mistaken and the recommended amount is 2x the pot so it would be more like 24 gallons of water for 4 plants in 3gal pots which is still a lot of water so i may do what you guys recommend and flush over a longer period...

i am using one large 4x4 scrog screen made of balsa wood and wire so all 4 plants will grow under that. i was thinking of buying some pumps or something to syphon the water but i'm interested in seeing how others do it first.

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...
