I'll subscribe. I like the documentation so far. What is the size of the room?

[macnasty]

Welcome Bigsby, and thank you.

space: Flowering area is 2'x4'x8' tall.

I should add that I'm a novice grower. Not too many grows under my belt. I do not grow glorious and beautiful supermodel status ladies, as I run into a few problems that I have yet to overcome. Hopefully those stopping by might be able to give me some suggestions. But I know enough to make any visitors time worth while.

I'll post pics tonight.

[macnasty]

pic 1: group shot. 11 days into flower. noticeable deficiencies.

pic 2: group shot. 30 days into flower. Look healthier. sorry poor lighting seems hard to tell there are 8 plants here, as the back row seem to be hiding in the shadows. plants are about 8-12 inches tall. ill try to take better shots next round with some supplemental lighting.

pic 3: close up of one. some leaves twisting a bit. not sure why. any ideas? over fert?

pic 4: underside angle of one plant. during veg i cut the bottom nodes off to promote air circulation during flowering and minimal side branching. im aiming for one fat cola. i also nip the buds a little further up once i transplant to flowering tub, but leave the fan leaves in tact. i'm guessing this promotes photosynthesis while the plant has only a few nodes but eliminates further side branching and helps focus plants energy towards the main cola.

sorry i didn't post any pics of clones, or vegging. i thought it would be more interesting if i just got things moving along towards the middle stage of flowering, for eye candy. if anyone would like to see root structure etc or anything prior to the pics below just let me know.

more next week.

Welcome Bigsby, and thank you.

Nice tight setup. I'm wondering if those leaves are suffering from too much light / heat? How close is that blazing 1K light? What are the temps? If you put your hand just above the canopy is it reasonably comfortable? I'm sure you know this stuff but just throwing out a few suggestions.

That's a serious fan for 64 s/f. I'm curious, do you use a fan speed controller? What's the noise level? Are you cooling your light with it, just venting the room, or both?

Ill be watching. :jointsmile:j[align=center][/align]

Hiya Truepunk and welcome.

distance from lights: between 2'-3' from light source, depending on position in tub.

temps: i don't measure them, but it's below freezing outside so there is a constant flow of cold air coming in. i'm guessing anywhere between 55-65 degrees fehrenheit. very cool nevertheless, and always cooler than room temp. no discomfort at all when placing my hand at the top of the canopy, plants are too far from the light for that.

air circulation: i forgot to mention that the in line vortex fan is acting just as an exhaust, sucking out all the heat from the bulb, and that the air intake of the closet is passive. both use 6" ducting.

That's a serious fan for 64 s/f. I'm curious, do you use a fan speed controller? What's the noise level? Are you cooling your light with it, just venting the room, or both?

while the flowering space is only 64 sqf the closet is larger. it's divided into 3 sections, one for a mother, one for clones and vegging, and one for flowering. unfortunately, the flowering space is far too small and the other two sections far too big. in any event the fan exhausts air from all three sections at once, which is 192 sqf, a size more suitable for a fan that powerful

[bigsby]

That's still a pretty big fan, depending on the length of duct, elbows, filters, desired rate of exchange, etc. My space is 220 s/f and I use a 400 CFM inline dialed back to about 2/3rds speed. It still sounds like a turbo prop though which pisses off the wife no end. I vent my mother / veg room into the flower room using a small duct booster fan.

Why separate mothers/veg sections or is that just how it turned out? I have mine in the same space. Anyway, looking forward to seeing this progress. Let us know when you figure out the leaf issue.

[macnasty]

astute observations bigsby. funny thing is i just got back from the hydro store and the guy said my leaf issue is probably the result of low temps locking out nute absorption (i made a post in the plant problems section of some issues i'm having in the later stage of flower). he says it could be a mag/cal deficiency caused by low temps. never thought that could be the case. i could a) throw a submersible turtle heater in the rez or b) do what you do and get a reducer to dial it back a bit. option b would be a bit of a pain, as i'd have to crawl up into the attic to tinker with the fan. not to mention that's a lot of work for just guesswork. on the plus side there is ZERO noise from the fan since it is on a completely different level from the grow room (my exhaust runs about 20 ft as well as the passive intake). the only sound i get are those made by the air pump, which is noticeable nevertheless.

in other news...

got some cal/mag from the store today. i'm going to begin using that. today is rez change and from now on I will be changing the rez each and every week, rather than every other week. hopefully these two changes from the program will resolve this annoying leaf browning issue. crossing fingers...

Sorry! I've been busy and when I finally got around to updating, the forums were down! i took pics at day 37 though so here they are! some notes: the differences in plant height are very noticeable now. plants range from about 6 inches tall to 12 inches, so the canopy is definitely NOT even. the pics of single plants are always taken of the biggest one. the centre of this plant already has a thickness equal to my fist! this plant will probably produce 2+ ounces. others as little as 7 grams, and still others somewhere in between. i feel like rez changes every 7 days is too much, especially for such small plants, so i've been going every 10 days instead, filling 5 gallons each time and topping off accordingly. i think i'll start keeping the food levels slightly lower too, as i believe my plants are experiencing burn at the tips and very dark leaves. once last point; i'm beginning to see very small brown dots forming on some of the larger fan leaves, especially the ones found on the largest plant. nute burn? mag deficiency? i'm not sure, but i think it will get worse gah.

ec: 1.8-2.0
ph: 5.6-5.8
rez changes: every 10 days



pic 1: looks like some nute burn at tips. leaves are probably too dark too.

pic 2: pic of the largest plant. the width of the centre of this plant equals my fist, about 4 inches of bud.

pic 3: close up of the top with the HID on. curling leaves dont make me too happy. is that over fert?

pic 4: under shot of biggest plant.

comments, suggestions are welcome. more day 43ish...
