[BlueberryNutz]

hello everyone, this is my first post on your wonderful forums. what i have for you is k2 from nirvana seeds. it is just showing preflowers but i cant tell m or f yet. i got some funky colored leaves going on in the mid range fans. i dont know if its deffiecient or possibly too much nutes. it shouldnt be the latter because she is on a very weak feeding regimen. i dont have a ppm or ph meter yet so i cant check those out. heres a couple pics. as you can see, the top leaves are coming in very nice and green, so maybe it has resolved itself and will only be in the old growth. let me know
-thanks

 

[BlueberryNutz]

i havent quite figured out how to put pics on here yet

Click on Edit on yoiur post and go to upload pictures at the bottom; pic upload should be fixed now though......

What soil is your plants in and what nutrients are you using how much and how often???

Welcome to ICmag btw

 

[BlueberryNutz]

its a dwc running PBP. it is a pretty weak feeding but i heard it was better to go under than over

 

[MynameStitch]

If that is tin foil around there; remove it; it absorbs more light and reflects heat.. not to mention HPS is not good for smaller plants, because one improper spectrum which can cause them to droop and they can become stunted.

Can you take a pic without the HPS light on?

Also can you fill out some of these questions so we can know more about your grow information?


What STRAIN are you growing?
What was the establishing technique? (Were the seed or clone?)
What is the age of your plants?
How tall are the plants?
What PHASE are the plants in? (seedling, vegetative or flower) are the plants in?
What Technique are you using?
What substrate/medium are you using?(Hydroton, RockWool etc.)
What is the Water temperature?
What Nutrient's are you using? How much of each if using multiple?
What is the TDS/EC/PPM you are using?
What is the pH of the "Tank"?
Are you sure your calibration is correct on your equiptment?
When was your last watering?
When was your last feeding change? (ie. grow-bloom-micro-additional)
How often do you clean your system: example: Flush out water replace with clean water and nutrients?
What size bulb are you using?
What is the distance to the canopy?
What is your RH Factor?
What is the canopy temperature?
What is the Day/Night Temp? (Include flucutaion range)
What is the current Air Flow? (cfm etc.)
Is the fan blowing directly at plants?
Is your water HARD or SOFT?
Has plant been recently pruned, cloned off of or pinched
Have any pest chemicals been used? If so, What and When?
Are plant's infected with pest's

[DirtDoctor]

it looks to me like it's probably a pH issue. Get a pH pen - or at the very least the color drops.

 

[BlueberryNutz]

getting a hanna meter for christmas

 

[MynameStitch]

If you don't want light getting in get some black duck tape; foil absorbs more light than reflects by far and it also traps heat and can cause heat issues in the bucket and bring up water temps; get rid of the foil.

I need to see pics without the hps light on so I can at least start somewhere as to what is wrong......

If I were you I would get tDS pen and a pH pen; growing in hydro without one is much like a guessing game unless you can read your plants.
How much nutrients are you using per gallon of water?
When the plants take out nutrients you have no idea how much to add and thus you can burn them very easily...... this is one reason why a TDS pen is needed.

You don't know your pH which it could be high or low; your using acidic nutrients and RO water has a low pH value.....,too high or too low pH can cause the plants not to absorb things properly; your water temps also need to be around 65 to 70 F if you got too warm temps you can have brown slimy roots which is a sign of root rot.

Have you checked the color of your roots?

 

[BlueberryNutz]

the roots are beautiful white and very healthy. i will either get a meter by the 25 or perhaps sooner. i need one now. i will have to make a special trip. its almost 200 miles to a hydro store
i will get the black duct tape after i get off work tomorrow

 

[MynameStitch]

I hate when stuff is so far away......

How much nutrients are you using? the dosage.. you using 5 gallon buckets? I can try to give you a dosage to use and you can pick up some ph test strips from a pool supply untill you get your meter and we can see what we can get done if you like.....

When you get a chance I would like to see the plant without the light on, because the light hides the issue; I need to see the color of the leaves and I can tell the texture by the colors so I know what to look for and where to start.

Black absorbs heat and light.

Black absorbs heat and light.

I'd go with regular duct tape. It's cheaper than black, too. If you want to spend a little more on colored tape, I'd go for white over black, to reflect light and heat.

 

[MynameStitch]

If you got black duct tape on the bucket it keeps the light out, black duct tape is also reccomended for all kinds of bucket grows; including krusty tree grows.....

White tape absorbs the light more and alows the light to be in there; if you put white tape on a bucket and close the lid with a camcorder in there and record it you will see there is light allowed in there; I have tried many kinds of duct tape and I find that black tape completely seals out the light, and I don't think it traps heat, because if this was true it would NOT be used for hydro grows; as temps are very critical in hydro.

Do not spend any money on anything but black tape, colored tape will be a waste; black is the only color that you can ensure all light is blocked out if you put it on correctly; this is why they recommend you using black hose lines than blue, because blue allows too much light to come in causing alge growth and clog your lines.

 

[SinsemillaJones]

Keeping light out depends on opaqueness not color.

Keeping light out depends on opaqueness not color.

White tape tends to be less opaque than black, but if you use it for the top layer (it takes several layers of tape to completely eliminate light, anyway), the white will reflect away more light and heat.

White appears white, because it reflects all the colors of the visible light spectrum. Black appears black, because it absorbs all the colors.

A black surface is actually the most light absorbent and heat retaining color you could use.

 

[MynameStitch]

Ya, so if you buy white tape why use it if you have to keep wrapping and wrapping to keep light out anyways? More $ and a waste....... It would take ALOT of white duct tape to keep light from entering a bucket..... it states right here about that.
May I ask how long you have been growing? Around here for a very long time black buckets are very well known for growing and keeping light out when you are growing in DWC.

Hence when it says when you use white buckets you have to wrap them around in black duct tape; pipe tape is black too. So if they are telling you white buckets need to be wrapped in black tape; wtf is the point of using white tape to wrap your buckets????? you want something reflective wrap in black duct tape and use mylar around your buckets.

It is imperative to keep light from reaching the nutrients in the bucket. For this reason, it is recommended to use black buckets for DWC. When using white buckets,they can be wrapped with several layers of duct tape or a layer of anti-corrosion pipe tape. Be sure to tape the lids also.

Algae needs light to grow. Ensuring no light makes its way to the nutrients through the bucket is the best way to prevent algae growth. Algae also thrives in anaerobic conditions (lack of oxygen) so be sure that plenty of air is being pumped into the buckets. I dont know the minimum amount, but you should not have any problems if you are pumping in at least 500 cc's/min of air per gallon. 600 cc's/min per gallon will ensure plenty of oxygen is being introduced in the nutrients.

Black, generally, IS more opaque...

Black, generally, IS more opaque...

But not much more than regular silver, which is cheaper. It's not the color of the tape, but the opaqueness that keeps the light out. And reg silver is also going to stay cooler than black.

If I pay less for 2 layers of silver tape than 1 of black and it does the same job of blocking the light and stays cooler, too, then I think that's the way to go. Adding white tape, white paper, mylar, or any reflective coating to the outside surface will minimize heat absorption.

A thick quality white tape might keep more light out than a thin cheap black tape.

Putting white tape over black would make it more opaque, it certainly wouldn't make it less so. You don't have to use white for the whole wrap, just the top layer, if you want less heat absorbed by your container.

If your temps are fine with black surface buckets, more power to ya!

[BlueberryNutz]

the top looks slightly deffiecient and the fans look burned. i dunno about the ph yet. i think it has 1 1/2 tsp per gallon of nutes whis was reccomended for seedlings. my guess is it needs to be strenthened a bit. i checked the ph with a fish tank ph strip. it turned yellow which was leaning towards the acidic side but i have no way of finding out how acidic at the moment

 

[SinsemillaJones]

Don't wait till X-mas!

Don't wait till X-mas!

Get a ph pen now!

Unless you're incredibly intuitive or very lucky, hydro requires close monitoring of ph and ppm.

I'd guess you've been under 5 ph quite a bit, and that girl aint gonna last much longer, unless you get your solution properly dialed in asap.

You can get ph and ppm testers on e-bay, if you can't make the trip to the hydro store anytime soon.

Also, you're using RO water with PBP, so you might be missing some micros. You should use Cal Mag Plus with that combo to get the micros.

In the mean time, you might try tap water with the PBP. The tap water will usually have micros and often will be buffered up in ph in city systems.

However, city water also tends to be heavily chlorinated, so let it sit for at least 24 hours to let the chlorine dissipate.

 

[BlueberryNutz]

i will give that a try then. i wont have a ph pen for another week or so. hopefully it will stay alive. if it starts taking a dive i will clone the 4 good sites and the legacy will endure haha
