Is my plant sick? Purple stems? check out pics>>>

[potsim420]

So we started growing and the plants we have from the original seedlings (the seeds were from buds i smoked in the past, strain unknown, all plants different)are doing great, they look great, starting to smell also..

the only thing is that they are starting to develop purple stems..

Is that a bad thing or just the strain of bud?

also we aquired a bigger plant from a buddy and the leafs are starting to droop and turn a yellowish color, also the stems are purple once again. use the pics and let me know what u think...

thanks appreciate the info.
peace.

What is your nute schedule. they look hungry

[Revanche21]

I've grown two plants before so im not an expert, but both were from bagseed and both stems got purple at the parts that the light hit. The parts that were shaded by other leaves were still green, hope that helps!

and the ph as well.

[italian04]

im growing with potsim....ph is 5.4-5.8
we are using GH 3part....the babies are about 2 weeks old using very low dose-less than 1tsp per gal

the bigger one is about 4 weeks old but has been transplanted and is showing slow growth. nutes are 1.25tsp/gal....the tips of the bigger one are turning yellow/brown. but it is just the very tip. it is not turning the whole leaf colors. the tips of the baby fan leaves are even a lil yellow. is it nute def or nute burn?? need some help. just raised the lights a little bit too. any help is greatly appreciated. thanks and peace

[JeffersonBud]

I usually don't use ferts until I see at least 3-4 nodes or they start to show the slightest yellowing in the lower leaves. yellow tips are a form of burn. I would flush with 5.8 p.h. h20 and wait a day or two. I went very slow with the nutes and my plants have turned out very well.

[italian04]

ya im bout to put it in pHd water(5.6) and leave it like that for a day or two. then ill add a low dose of nutes after that. prob a tsp/gal and its in about 1.25 gal of water. its our test run so when i get my seeds i wont use fert for about 3-4weeks. thanks so much for the input. peece

[JeffersonBud]

I wouldn't even put that much in. is that 1/3 of what GH recommends for veg? I would half that or even 1/4 it and increase slowly.

[italian04]

ok well the first one they have on the bottle is 1/4 tsp per gal...so ill do that. how long until u increase after that? like every week or so?

[JeffersonBud]

Only you can make that determination. Every plants genetics are different. I never go by the bottle but from what I see. There is enough info on this site and smart people to help you out with every problem / deficiency there is. Never go up by more then 30% at a time though or you will shock them. Sometimes you might need to cut what the bottle says to put in, into much smaller fractions.

[italian04]

ya for sure...i know i fertalized too early but once get my fem northern bright ill know better. thanks for the help JB. i will have pics up soon once my other babies grow i lil bit more. they are a little over 2 weeks and are flourishing. just changed all the buckets today so they should grow quite a bit this week.

I can't say for sure. But i've read about and experienced purple stems several times...well..everytime actually.

What i've come to find, as far as the purple stems are concerned, is that light intensity/available light has a lot to do with it. I have 4' T8 fluorescents in my veg room and everything in there has purple stems, but otherwise healthy. As soon as i put them under my HPS in flowering the stems go green. Perhaps it's the new nute solution in the flowering Res, but i tend to think it's the lights that bring on the improvement.

who knows. all my grows so far start off great then crash about 4 weeks into flowering. Damned learning curve. i hope i was able to help. good luck.

Reddish purple stems are usually a sign of phosphorus def. That's why I'm thinking lockout. And I'm curious how often you actually check your ph italian.....at least daily?

True purple stems are a usually strain related imo......it takes awhile to be able to tell the difference but generally there is one. I personally have found that def related purple stems tend to be more of a reddish color.

[italian04]

i check the pH 2-3 daily. IMO it looks like where the light is hitting is changing the color just a lil bit. im pretty sure its not a lockout or a def. the other branches shaded a little bit from the rest of the plan are still green. remember, the bigger plant was transplanted so im really not too worried about it. i have my cannazym coming in the mail. the roots are starting to grow tremendously on all the plants. and the 2 1/2 week old plants look great!! thanks for all the advice WH. b looking for updates on the plants in the hydroponics section under "test run in DWC" i got some new pics up. peace

[Weedhound]

Checking two or three times a day ROCKS!! Good for you to put the energy in. :thumbsup: Hope your grow rewards you well for your efforts.

Good luck. :)

[italian04]

oh ya i stay on top of it. but i get pH down to about 5.5 then by the next day its at about 6.3. i did not ph adjust my hydroton this time which is adding to the rise. the roots are growing like crazy. am i going to have to flower the plants b4 i can tell if they are male or female??

[NaughtyDreadz]

could it possibly the temp??? maybe it's too cold... I remember reading somewhere purple stems were due to cold temps... nothing to worry imo

[italian04]

no temp stays 80-85. im waiting on my air cooler to get in this week

[Revanche21]

idk the temp in my grow closet but its definitely around 70-80 and the stems that get hit by light are purple and underside and parts not hit by light are not purple

I don't think it's anything to worry about

[italian04]

i dont either. just got my air cooler in today. fuckin sweet!! i do have a couple questions tho. so my closet is going to have a veg area and a flower area. is it bad if the 1000w hps mixes with the light in the veg area?? should i keep the two areas separated all the time. i have a huge tarp i am going to put up so the flowering area stays pitch black at night. but during the day is it fine to have both sections open??

[elskeetro]

I have both Veg and Flower in the same room, they face each other. I have a black plastic curtain that i roll up when the flower lights come on to improve airflow/heat/etc. and roll back down when the lights go off to block it from the longer light of the veg side. It's been great so far. If anything the veggie's love the little bit of red/orange spectrum from the HPS in addition to the blue spectrum of the Veg Fluoros.

I'd say it's ok to let your lights hit both veg and flower during lights on, but during lights off you better make sure they are separated really well.

just my twin Lincolns.

[italian04]

ya for sure. thanks alot! but how do you control temp and humidity on the veg side, when the curtain is down after dark for flower side? thats kinda what im thinking about now. it might get to hot/humid. my flower side has a door nxt to it that i can leave open. also i just got my cannazym today and added about 1tsp to each bucket(1.5-1.75gal). they look beautiful now hopefully i see some results. have pics up in a couple days. thanks for advice skeet


peace

[elskeetro]

Well, during the summer i have no problem with controlling heat during lights off...it's when the lights are on that's the problem!!!

During the winter i have an oil filled space heater (the little radiator lookin things...) to keep it 72F when lights are off. when the lights are on they put out enough heat to keep it warm in there.

I'm still trying to get my humidity under control. Looking into a dehumidifier or AC to keep temps and humidity down.

thanks

PS - It just occurred to me that we seem to be thread jacking. let's start a new thread if there's more to talk about. Sorry to the OP!

[italian04]

no no my roommate started the thread :thumbsup: ya so my air cooler isnt the greatest. im prob just gonna put that in my room. im looking into portable a/c's on craigslist. pretty expensive. my temp is 78-86f and rh is 55-60. so im not in too bad of shape. plus i still have a nother month till flowering starts. craigslist has the a/c's but they are a hot commodity.

[elskeetro]

yeah. you are in a better spot than i am at the moment.

My temps go from 72-89 and RH goes from 50% when lights are on to 82% when lights are off!!!! i'm just waiting to see my entire crop go to rot!!!!!!!!

I need to get a Dehumidifier ASAP. I was gonna try a lot of Calcium Chloride (the stuff damp-rid is made of) and see if that was a cheaper solution. i just haven't gotten out to the pool store to get it.

We;re a one car family and i'm currently sitting at work (been here 13 hours now today...just waitin for the wife to get out of work and pick me up!!! Good thing i have this board to keep me busy)

Check out the hail we had today...crazy! everyone who had their car in the lot has golfball sized dents in their cars. lucky i didn't have the car!

sorry for the crap post...just killing time...soooo bored.

thanks,
skeet.
