Ebb & Flow problems - plants seem small

What's wrong with my plants?

2 weeks veg, 1 week into 12/12. So small!

Lucas formula + AN Big Bud, AN B-52 and AN Bud Candy put in yesterday.

EC about 1.0, was 1.4-1.6 in veg.

Strains are Barneys Farm L.S.D on side #1, Whitelabel Super Skunk on side #2 and one big Zamal x White Widow in the middle and three L.S.D cuts on the #3. (moved the cuts on the other side of the system and replaced the smallest Super Skunk from side 2 to the other corner close to picture)

Should I add a P-K additive?

They seem so small!

That is a 1,5L (50 fluid oz US) bottle.

I wish they would take off...

well i am sure everyone is going to tell you the same thing. we need pics of the plants to see what you mean.

Side #1

Side #2

Side #3

There ya go. I am pretty sure I posted the album link in the OP but maybe it is invisible, I am pretty sure I made it public folder though..

 

[newbie2006]

The cut on #2 had tiny roots of a few millimetres in lenght when it went to the system instantly recieving that 1.4 EC nutrient dose...

The cuts on #3 1/3 has rooted, 2 others still rooting.

.......


There ya go, that was an awful lot of questions.

Hopefully now you get a better picture!

Dump all the additives right away and mix your Lucas 1/3 strength of where it is right now. It is very easy to stunt growth with too hot of a mixture without seeing signs of burn. You are running more nutrients right now than I would in full flower. It's easier to recover from too little than too much ferts so run them weak until you know your plants. It would also be helpful to know your lighting before anyone can advise on slow growth.

Your nutes are wayyyyyyy too strong at this point of the grow...

 

[newbie2006]

Yeah I know I have been going on high EC's and lots of nutes, but last time I ran Lucas at 50% until this stage, and then cranked up it up to full 100% Lucas, and the plants stretched wayyyy too much to get good yield. These are the cuts of those.

So thats why I am running these liquids, to control the explosive growth!

You think its a bad idea?

 

[Aerohead]

Well, stretch is usually from lack of light or too much N. I would simplify things if I was you and drop down to a very mild fert mix. I don't know enough about your grow environment to be sure but looks like too high EC.

Good news is it's just slow growth, your plants don't look bad, happens to all of us, we recover and growth becomes very rapid, I am sure this will work out soon.

 

[newbie2006]

Before I added the flowering additives, the EC was at 0.75, so the plants had eaten some off that 1.4-1.6 to start with.

Any other opinions?

 

[Aerohead]

In my opinion, those plants aren't large enough to pull the EC down that fast by feeding, something else is going on. From what you said, you added the additives to slow stretch, seems it worked all too well. Makes sense to back off a bit, What are you using for light???

 

[newbie2006]

If you read thru those questions I answered on this thread, you'll see this;

What size bulb are you using? 730w sulphur plasma, LG, 4500K

 

[Aerohead]

Apologies, I did read the thread and still missed it. I must say, not familiar with that light at all but the spectrum looks good for veg and the wattage is there. Not enough light was my last guess, I am stumped, I am sure someone else will jump in and help out soon.

The plants look like the will explode when you figure it out, they look healthy.

 

[newbie2006]

I am starting to suspect macronutrient defiency, as I have been running these liquids for an extended period of time. Maybe I should add more floramicro, but that would result in excess N. Hard choices..

And as I said, I'm getting the light closer in a few days.

 

[HydroCab]

>Is your water HARD or SOFT? Soft<

Could this be the problem? i believe the difference between hard and soft is hard has extra Ca in it and soft has extra Na

if u have a water softener then it could be too much sodium. Unfortunately you cant see exactly what is in ur water without a GC/MS machine...EC just don't cut it

EDIT: lol just saw u stated that u dont use a water softener scratch that... still could be too much Na coming straight outta tap

 

[Rednick]

Whenever I see tri leaves that usually indicates too little light, IMO (or stressed/revegged plant).
See if you can get a report on your tap water, in the US they must do an annual testing, will tell you a lot. Get it from your water provider, or city if you're on municiple supply.
Is r/w getting soaked everytime you flood? If so, that is bad. You want r/w right above the water level to mate with clay, force the roots into the clay.

Also, if you post your problems in the 'Infirmary' you may get more hits.

 

[cocktail frank]

you are trying real hard to kill them girls.
calm down w/ the ferts.

 

[bullseye]

when you put cuts in flood n drain they need to be realey rooted up well like rednick said cubes just above water level if your cubes are getting saturated every time you flood that will cause slow growth pre veg in small cups of coco works great u get exsplosive growth

 

[Ganjagrower1]

maybe you just didnt veg long enough. give the roots enough time to grow. you are talking about the roots only being so long on the one. you should have a good root zone before you even start to flower. just my opinion.

 

[creeper327]

First small roots account for small plants.
Should have vegged longer and established better root system.
Mutated leaves usually are from stress to the plant.
Lower ppms and add somekind of rooting solution to res.also maybe bring down flood times
