....people, I'm a little concerned that I've made my res too small at the bottom of the bottles.
I used a mixed grade perlite which maybe hadn't left enough gaps between particles for sufficient water to sit.
The bigger of the plants seem to all but empty the res in 12 hours, though I understand there is wicking and there will be water throughout the perlite.
The pot doesn't feel light particularly, am I worrying about nothing? I could do with leaving them unattended for a couple of days next week. Am I going to have to modify the pots to make the res bigger?

Growan, have you flushed the containers lately. If not I would flush them with pH'ed water a few times and then give them clean pH'ed water with Cal/Mag for the next waterings.

No, they haven't had a flush. I don't see it doing any harm to try it though. Theory being if I get them to a happy pH, then reintroducing nutes at the right strength in the right environment should benefit?
I did think I'd underfed for a while which started all this off, but I guess it doesn't hurt to hit the reset button...

Are those pictures taken under the grow lamp, if so try and take some without the light, flash is ok. Post them, I am going back to read your post and see how you are doing things.
Just looked again and I can see the lights were out.
I was not able to find how your growing. Would like to know, if you have posted it just give the post # and I will go read it. Thanks

Thanks for taking the time, I'll give a quick recap...
100% perlite in 2l bottles.
Mixed seeds, mostly regs.
Dyna-Gro Grow, Mag-Pro and Protekt. Started at ¼ strength, now up to full strength once I noticed how pale they were (HPS hid that well!!!)
Have been aiming for pH 5.5 to 6, runoff has sometimes been right up to 7 though?!?
Temps vary between 21°c and 28°c.
Started under 275w HPS gradually up to the full 600w now.
So that's where we're at. Aside from the pale down turned leaves and what I consider slow growth, the stems seem reddish or purple.
The leaves feel right, not too papery, but this one is has quite pronounced differences between the 'troughs and peaks' as it were, perhaps just the way the plant is, perhaps a clue?
The poor thing looks terrible in that picture. It might not be that bad in the flesh....?
My best guess is some kind of lockout, perhaps due to pH. Although the paleness suggests nitrogen, I wonder if it might be a magnesium issue as the stems are so off colour?
Any insight?

Disclaimer: just throwing out some questions, I'm not really sure what's going on...
What's your water source? quality/pH/ppm?
Over how many feedings did you go from 1/4 strength nutes to full strength?
Also, full strength? Have you spoken to others using this nutrient regime to verify at what strength they feed at? I'm pretty sure I remember a couple guys using DG that feed at 1/2strength or so...
Do you even have a ppm meter? Its kind of a necessity in hydro, unless you feel very lucky.
I know you're getting conflicting info here, but it seems to me that you increased the nute strength very quickly and maybe don't have a ppm/tds/ec meter to know how strong you're feeding them.
I would flush as recommended, to dilute the res and then water with 1/4 - 1/3 strength nutes and hope that sets them straight.
I defer to just about anybody though on this topic, I haven't grown hydro in a long time and I could be way off.
Hopefully I helped stir some thing in your mind.

Water is rain or tap alternately, seems to be consistantly 7.2
I don't have a ppm or ec meter, naughty I know but I thought that passive hydro was supposedly a bit forgiving of us Luddites...?
I went from 1ml per 5l to 2 ml for a week, then up to 4ml (1tsp)
Now I thought i I was in line with what I'd read elsewhere, and I'm at the same levels Dyna-Gro recommend for hydro with a res (recirculating systems mix much stronger, says the label)
I think we need to have ourselves a flush and go on from there....
Thanks for pitching in. I'll go see if I can find some Dyna boys to set me right on strengths of feed...

My last comments on this, I would definately get a meter! How are you measuring your nutes? Oral syringe, Hydro measuring device, kitchen measuring spoons. Your rates will vary dependent on what device you are using to measure. My kitchen teaspoon is almost 8 ml, I use an oral syringe now for liquids and a Raw-soluble measuring spoon for any dry measurements.
Take a look at this and see if you can find a match.

Good basic info. I saw your using Mag-Pro, I cannot find the percent of Mag in the product.
Are you using a Cal/Mag product?
Good luck, if I can think of anything else I will reply, Be nice if I could think at all, LOL

I'm using a syringe from kids medicine. I also have a set of plastic spoons meant for kitchen measurements. The Dyna-Gro measurements are in tea spoons, and I got the 4 ml measure from the ½ tsp recommended, as I recall...My last comments on this, I would definately get a meter!

Thanks for the decent resolution image from the Bible, I had only found a shitty one this morning.
I think I've read the grow weed easy Linky before, but I'll read it again, as i remember its a gold mine.
And.... I'll buy an ec meter. Right now. On eBay. I promise...

When I initially grew hydro I didn't have a meter. But I always mixed my nutes in the same order and ratio and would titrate the nutes into the water to meet plant needs.
I would start with a small amount and work up slowly and make note of plant response. It took some messing with at first, but eventually plants stopped dying
I had a strip test pH system and would first add all my nutes and then a couple drops of pH down and I'd be set.
How're the plants looking today?

G, if you are using those plastic spoons, use your syringe to check out the ml in the plastic spoon teaspoon. I did mine and got 8ml per teaspoon. That can really make a difference in the amount of product your putting in.

I'm using ph paper and a digi meter too, just in case I feel I can't trust one or the other!When I initially grew hydro I didn't have a meter. But I always mixed my nutes in the same order and ratio and would titrate the nutes into the water to meet plant needs.

I'm using the Protekt first as i read that it needs to bond with the water molecules first in order to be effective, then the other nutes. Who knew that I should have paid more attention in every subject at school and it wasn't just for playing AD&D at the back of the class...
The babies have been in the dark since 9am, so I can check them again in an hour or so. Hopefully they'll be greening up a bit. The bastards.
