DWC plant starting to claw.... help me

[Homegrownfor2]

Hi this is my first grow and things were going well until two days ago. After the first week I decided to do a water change. After the change in noticed that two of my plant seemed to be starting to claw and the other started to turn yellow. Due to that I came to the conclusion that I screwed up the nutes so I changed the water again and went really light on the nutes. Well one full day after the change and the plants still seem to be claw shaped. What could be causing the clawing? I checked the ph and it was acceptable.

Grow details
•2x4x5 tent
•250w hps
•10gal tub with 3 seedlings(I plan on only choosing one after a few weeks).
•Top fed dwc with water pump pumping water up to the plants.
•Two air stones with air pump
•temp 70° to 80°
•Humidity 30% to 40%
•general hydroponics nutrient trio plus hydroguard
•2 small fans inside tent
•exhaust system

wait a couple more days. if it doesn't fix itself or gets worse, follow the .pdf i just posted. shake the shit out of your bottles and add them one at a time (micro first) in aerated water or do heavy stirring after each addition. just dumping the 3 parts in the rez can cause lockout.

or grab a bottle of flora nova bloom and mix it at 1/4 or half strength. im a fan of lucas formula and nova bloom is the easiest.

your light looks a little close.

what kind of water are you using? I'm guessing tap since you aren't using cal mag? if so, remember to let it breathe a couple days or use a safe dechlorination solution.

im new also, so im mostly guessing.

Thanks and yes I am using tap water. I'll have too look in to dechlorination more I didn't think it would be a problem.

Just leave the tap water out overnight to reid the water of chlorine, its in gasius form and will dissipate over night.
You could change the rez to PH adjusted water then change to a week seaweed solution at half strength for a few days, and then do a fresh res change with a weeker solution and add to it as nessesary up to half strength max for plants that size IMO (although I would stick to half strength seaweed solution for 4/5 days or longer untill you have a nice fresh bunch of new and older reinvigorated roots and lush new green leaves)...less is allways more for plants untill you become more aquainted with them & their needs.
but sounds like you've been given some good info (not read it though), but hope it helps Rudi

Thanks rudi i checked this morning and the newer growth doesn't seem to be clawing. Its in 50% strength nutes right now im going to wait another day and see what happens. Do the leaves that have already clawed go back or do they stay that way?

 

[rkymtnman]

50% = way too strong nutes for such little ladies. what ppm/EC you at?

 

[Homegrownfor2]

Let me be more specific 50% of what the suggested amount for a seedling is. So 1/8 tsp per gal vs 1/4 tsp per gal. I don't have a ppm meter so I'll have to tell you after I pick one up

check out the com-100 by hm digital.

good. ppm/EC meter is invaluable when first starting hydro. take good notes.

you using cal/mg at all?

what is your pH at?

 

[rkymtnman]

if you can get RO water, that would help too. eliminates water as a possible source of a problem

 

[Homegrownfor2]

Ph is good around 5.5 to 6.0. I'm buying a digital ph and ppm meter today. I am brand new to this so I'm learning as I go. The step by step I followed for my setup skipped alot of detail I'm learning the hard way.

 

[rkymtnman]

pH sounds good. 5.5 to 6.1 for hydro.

my 2 suggestions would be to get one of those 5 gal jugs at walmart of RO water and some cal/mag. the problem with using tap water is you have to add in the ppm's of it to the total ppm. so if your tap is 300 ppm and you are adding 200ppm of nutes, your total ppm is 500 which is way too much. with RO water, your ppm is 0 so you are only adding whatever nutrients/additives you put in.

the good thing about hydro is that you can identify and fix problems quickly. the bad thing about hydro is you can develop problems quickly too.

I think I will grab some ro water and give that a try. I just ordered a ppm and ph meter so 2 days til that gets here. We will see how it goes I'll update when I get the ppm meter and such. Thanks alot

 

[rkymtnman]

no problem. are you using tap or well water now?

although buying and refilling those jugs at walmart is kinda a pain, it does make it easier to have a clean slate for when you add your nutes. i'm still doing it 7 years later. lol

 

[Homegrownfor2]

I'm using tap water at the moment

if your muni water has chlorine/chloramine in it, it's probably negating the hydroguard. the one suggestion to let your tap sit and bubble for 24 hrs is a good one until you switch to RO

 

[Homegrownfor2]

Ok I'll try that. I'll have to see if I can track down some ro water

As a newbie myself, the meters I bought are decently priced and work well. Head over to amazon and check out the HM digital COM-100 and bluelab ph pen. Great tools, but get calibration solution for both. The General Hydroponics 7 is what I use for the ph pen.

never a bad idea to keep a bottle of the pH drops on hand, the ones that go from yellow to green depending on pH. if you suspect your meter to be acting up, double check with the pH drops. recalibrate if needed.

The ph pen I shared can be tested at 7, 4, and 10. This let's you truly calibrate it for accuracy. It should also be calibrated weekly.

I have never had luck with the drips. The ph test paper works well for me though.

yes, but wouldn't you be doing the same thing with the calmag? it may be 50ppm as opposed to 200, but it would be measured separately from the other nutes correct?
