Hydroponics Question and Answer NewGrowth Style

Hey NG check this out.. Noticed a lil discoloration on some of my fan leaves and was told it was prolly a deficiency..Got some cal/mag and added it to the mix over the weekend. Whats it look like to u? If it is a a deficiency do the damaged leaves come back green? It wasnt real bad and corrected it soon as i seen it.
Also, Ho do u use the cal/mag.any input would be great thanks.

It's really hard to tell from your pics, the HPS kinda washes them out. I tell this to everyone: Micronutrient def is VERY rare and is usually caused by Ph imbalance or nutrient lockout from over fertilizing. Damaged leaves will never heal, new growth is the best indicator of current plant health.

Do you have a grow journal? I can check it out if you would like, might give me a little more back round info on what you are doing.

Yea man right here..I did have a ph problem as well my pen needed calibration for who knows how long.. My nutes have never reached over 1500 in flower.Anyways check it out.

I looked through it I think its just a low light situation. You are running a 150W HPS? Also how far are you into flowering?

I got 2 150's over the tub..I had them really close to the tops for too long and heat stressed alot of my cola fan leaves. I know its not much light.Then on top of that my ph meter was jacked up for awhile.. I moved things around and got the lights about 8 inches from the tops..I started out horribly..The tubs a lil less than 3 sq.ft.. I dunno.
Since i raised the lights and got my ph in check the NG is nice.. No more bumpy crooked leaves.. I flowered them directly from root growth so they were all about 5-7 inches when started..
Ive been thinking its a deficiency cause of the amount of plants i got in the tub.
Who knows tho.

Deficiently is obvious just follow my guidelines:
1.Water level drops PPM goes up: Drop your nutrient strength in relationship to the PPM rise.
2. Water level drops PPM stays the same: You may be able to fine tune you nutrient strength, if growth is vigorous leave it alone.
3. Water level drops PPM drops: Raise you nutrient strength in relationship too PPM drop.

I saw the old deformed leaves and thought Ph but you said you already corrected that.

Micronutrients could have been locked out of some of the growth you are seeing necrosis. Possibly just the result of your previous Ph issues.

Don't worry too much just monitor it for now.

Thanks brotha.. I am watching it closely.
Im currently using Bot. pro grow and flower nutes..cal-mag,fulvic acid and kool bloom..
ive noticed that cal-mag brings the ppm up considerably. and was curious how u would administer the other 2..should i use more backbone nutes and supplement a lil kool bloom.just trying to put my finger on the deficiency. what nutes will better supply the plants with what they need at this stage.

If you are using three part nutes your base should always be the majority of the nutrients you add. Bloom is added more as the more flowering progress'.

I don't like three part nutrients thats why I use Ionic. They also have boost which is good for adding weight later in flowering. Simplify your nutrient package and it will be a little easier to diagnose deficiency and monitor PPM levels.

I have another question about hydro. I was going to have 3 plants over the reservoir and have a canstant sprincle of water going into the plant pots and dripping back into the reservoir. would a constant water supply kill them and if so how can I get arount this with out buy much more stuff as I am running low on money.

lol at the amount of typos in that question

Depends on how you set it up. If you use rockwool for example the drip will have to be periodic so you don't overwater. If you are using hydroton you can run a continuous drip but you will need a drip ring to promote even root growth.

It's ok . . . I understand

So it has been a week since I bought clones and put them into my drip system. I was given a lot of wrong info about the feeding schedule, but figured out that I was over watering. I stopped watering and quickly noticed a difference. I now have several roots poking out the bottom of my rock wool and my plants look to be growing.

Now that they have been growing I am challenged with a new problem. My roots are turning purple. My PPM for the first week was around 300. I just set up me next rez and my PPM is around 540, but have not fed them yet. I think the PPM should be higher. What does every one think?

Thank You

Matt

Have any pictures of the roots? What type of nutrients are you using? Any additives?

Sorry... I said that my roots were turning purple, but what I meant to say is that my stems are turning purple. I am using Advanced Nutrients Sensi Grow A & B, Dr. Horby's Tarantula (also by Advanced Nutrients), Dark Energy, and Hygrozyme.

Thank You

Purple stems is not a big deal but it can indicate a Phosphorus def. I would just watch it for now since you said your cuttings just rooted.

Ok thank you.

Another quick question. Awhile back I trimmed off the leaves that were yellow and nothing has grown back. Why is this happening? I looked at the places that I trimmed and they are kind of brown. Before I trimmed the leaves off I cleaned my scissors with some alcohol rubbing pads. Finally, where should I trim the leaves off at? I cut some leaves of right at the base of the leaf. So now I have empty stems.

Thank You

You have to trim closer to the axial growth tips to promote growth. Cut that stem off and you should get some new growth.

THANKS MAN, BUT AFTER ALL THIS TIME OF WORRY....

Haha!!!! So after work i went to a local hydroponics store and asked if i could use my hydro nutes on my soil grow and explained that i was phasing out soil and thats y i didnt have any soil nutes and he said it would b alright. So i went home, made my mixture, poured it in, left for 5 hours, and when i came back it was like i had 2 completely different plants!!! Theyre all perky and happy now!! Thats all i needed the whole time? Man i feel like a jackass, but im glad i didnt kill my babies while i was trying to figure it out. Now that theyre healthy, im taking a cutting from each, and starting my flowering stage

woohoo!!!!

Also i noticed i have a few spider mites that i thought i had gotten rid of. Anyone know a cheap and easy way to get rid of em? I was told to just kinda rub lightly on the leaves where they are to squish em, and make sure u spray the underside of the leaves cuz they dont like wet areas, but apparently that didnt get all of them
