Slow grow at veg-stage.

[Litz_C]

wassup everybody. I'm a hydroponic (ebb and flow) grower and facing some weird problem haven't been face before. There the problem, I have some bubba kush and some afgoo vegging for like 2 and a half week already. They don't stench a alot and size still really small. I was thinking they were stun or shock but they still growing some new leaf out, right now only size of 5~7 inch and grow slow as hell(not even a inch in a week). I'm growing it indoor and i kept my temp around 66~71F and RH around 50%~60%. ppm stay around 400~500. Oh i forgot to mention all of them are newly root before i put em on Hugo under 1000w lights runs on 24 hours. I was accidentally applied 900 ppm nutes and burned sum leaves . Is there any way to save those baby put em back on track again. It painful to watch em not growing at all. Thanks.

Are they from seed? If so that doesn't sound too inconceivable, as the first 2ish weeks of a seed plant's life is a bit slow, then they start to take off from there.

PPM and environment seem alright. Why are you running the 1K 24/0? You may get some benefit from 18/6 or a different light schedule, I'm not sure, but most people seem to prefer something other than 24/0.

nah not seed it clones. those clone just rooted when i put em up to the 1000. i been grow over 2 years it the first time i experience such a difficult problem.

 

[GET MO]

maybe give um some rhizotonic to stimulate them roots a lil more...

 

[swampy_nz]

honestly dude,to me this is completely normal.
I got my clones already rooted in jiffy pots which i transplanted into 4" pots with soil mix.the first 2-3 weeks the growth was very slow,but after the 3rd they really took off,especially after in transplanted into 5 gallon pots.
check out my 3 pics.each is a week apart.see the explosive growth in the 3rd pic

You should probably figure out how to type/talk first, even if your from the hood that's go reason to talk like a tard. If it's real bubba she's a slow vegger anyway. Plus inches per weeks isn't shit

 

[JamieShoes]

here's a real newbie answer for you... maybe move the light away a bit and make them stretch for it? (ok flame me now :smile: )

 

[Litz_C]

things seem a bit better today they finally stretch a little bit. My been set my lights away from my plants like 3~4 ft.

What temp is your sol'n at? What are the temps in the root-zone? Maybe your roots are chilly -- cold roots grow slowly. Also, I've found E&F to provide the most optimal growth rate if you flood and drain as quickly as possible (my working hypothesis is that it allows for increased O2 in the rhizoshere), so you may want to try installing a couple more drain fittings/feed hoses on you table, to increase the speed at which you flood and drain. I should note that this probably won't make a big difference if you use rockwool and not hydroton, cuz it holds so much more water.

Heh, are you new to icmag or something? A good 10-15% of the people here type with a heavy amount of slang. And about 5% type in such dense slang that they're completely incomprehensible. But I digress, this poster did post up a comprehensible post and provided decent information about his grow... So perhaps you should lay off a tiny bit. Just sayin'.

 

[Litz_C]

i kept the root around 60~65F they all grow out of rockwool bottom already. Since the algae been grow on top of the cover of rockwool and slow down on the feeding already. And i don't use the feeding tube while on rockwool. What is the ideal temp for the root to be @? Thanks

Nope I've been on here for 4 years this is the first I've seen. Most people are well educate that I've seen. I was in a bad mood but if you can't even type English that's bad


And 3-4ft is way too far away to have your lights. I have a 1k in a batwing with a fan blowing across an I keep my light at about a foot and half away maybe two

 

[Philosophelon]

The ideal temp for the rootzone is ~68F. If I'm running CO2 and higher air temps then I might raise it a bit, especially in soil, but you don't want to go too high with hydro root temps, as warmer water holds less dissolved oxygen and is more likely to promote root rot.

Also, algae on top of your rockwool doesn't hurt anything. I'm not sure if you said that you have slowed down the feeding because of the algae, but if that's the case you don't need to do that.

What size cubes are the plants in?

This is an international community. Getting pissy about the quality of someone's English is really unreasonable. If you can't understand this person, help them be understandable. There's no reason to talk down to them.

I apologize, I wasn't in the best of moods that night. Been having wicked bad carpal pains sometimes I get a bit moody

this is a problem that I had for a little and had no idea why untillllll I got a nifty lil c02 controller.

are you running a sealed room?

if you are running a sealed room you MUST supplement with c02 in some way otherwise your plants will consume all of the c02 in a small room in the matter of a day, if not hours.

ambient atmospheric air has about 300 ppm c02 right now, if it drops down to 100 ppm, your plants will hardly grow at all regardless of perfect lighting/nutrients. I have my rooms completely sealed and have a chart to see the readings from all my different instruments (temp/c02/etc) 6 decent sized mothers would consume 500 ppm in less than an hour from a small room.

I had 6 clones started as mothers in the room before I started using c02 and noticed inCREDIBLY slow growth. a few months later with a different batch of clones now supplemented with c02, i have incredibly FAST growth.

I keep my roots at 67 degrees F regardless of c02 or not. the c02 enables me to run a higher ROOM temperature and actually the plants thrive a bit more in 80 deg temps

 

[Litz_C]

not really a seal room i m running right now. i got a exhaust fan on top the the ceiling to blow all the air out from the room. Been thinking about using a co2 tank before but somehow gotten lazy off the idea. Isn't the co2 generator/controller kind of pricey?

 

[ourcee]

yeah a quality c02 controller that does a good job isnt the cheapest. if running completely sealed, its a vital must though.

if you have fresh air being circulated into the room, even at a fairly low CFM, you should be just fine with the 300 ppm thats standard for our atmosphere right now.

you should be able to get a regulator/solenoid and timer application for 125-250$ if you look around. from there it is just a matter of dialing it in to put out the right amount and when.

not as fancy as the computer controlled options but also saves you a 450$ controller in addition to the 125-250$ c02 regulator combo.

this also doesnt factor in the tank but you can rent the tanks on a month to month basis from local gas suppliers, tell them you have a mig welder, a small one tho which you only use on the weekends so you just need a small tank.
