Still not fixed =/

[unlearning]

Have stabilized PH, lowered nutes and raised nutes and still no noticeable difference. Slowly but surely working it's way all the way up the plant, I'm getting frustrated.

Under 4 Floros, in 50/50 Vermiculite/Perlite
PBP Bloom and Cal-Mag+
5.6-5.8 PH going in, 5.8-6.2 PH Coming out, depending on how much Excess water I give them.

 

[Guest]

ph seems a little low going in.

rusty spots like that usually denote ph problems. you said you altered the ph? did you drastically alter it or gradually alter it? a drastic swing in ph is BAD for your babies

 

[SEEDYNONO]

are you using tap water or ro?

how much pbp and cal mag are you feeding exactly?

 

[SEEDYNONO]

also that looks like what a bottom part of a 2 litre bottle u are growing in.. just want to make sure you have plenty of drainage holes in the bottom?

 

[unlearning]

rkrone: I was at frist feeding 6.3 as per soil PH, I watered with a 6.0 then a 5.8, then 5.6 gradually to get the runoff to come out around 5.8.

Seedynono: RO water, I was feeding a 6/2 PBP-BH/CM+ and raised it up to 9/3 and then 12/4 and 15/5 throughout a few weeks time to see if I could get some sort of a response out of them. I got a few Burnt tips as you can see in the pics but thats all. I lowered feedings back to a 9/3 and still showed no difference.

Thanks for the advice keep them coming guys.

You should cover your containers to keep light from the roots.

Here was part of my answer from some time ago...

I came up with this for flower....

11.36 ml per gallon pbp bloom hydro + 3.86 ml cal mag plus
n 100
p 27
k 131
ca 65
mg 29

2 1/4 teaspoons pbp bloom for hydro + 3/4 teaspoon cal mag plus per gallon of water. (3.8L)

This gives you 100 ppm nitrogen. If your in veg still with these small plants, this would also be good. When you want to kick in the turbo on these babys, bump n up to 150 ppm. Drop your fert water down to 5.6 after mixing. Continue using this ph till it gets below 6.2 in your runoff. I bet the perlite is causing the ph to rise. It can have a ph over 7 to start. You might want to apply the small dose of epsom once and then resume the 4:2:1 ratio. The lucas formula is designed for flowering plants. The above recipe almost is like Johnsons nutrient formula but has less calcium. Compare. See page 11. http://vric.ucdavis.edu/veginfo/topics/hydroponics/hydroponics.pdf

Make sure when you water/fert, you get some runoff. This will prevent excess salt buildup.

There is some confusion about net weights on the bottle so your calculations may vary slightly but not enough to be of concern. The lucas sticky in the hydro section is way off and wrong for pbp.

I believe you still got mag problems. Apply a small boost of just mag. Try 1 teaspoon epsom per gallon of water once. You could also spray 1 teaspoon per quart once instead covering both sides of the leaves.

Just because you make an adjustment to the nutrient solution does not mean the plant will be like that immedietely. Plants slowly accumulate salts within from the roots so it may take quite some time before changes become visible. This is bad if you overferted because it does not go away even with leaching for some time. You will be applying the epsom once to allow the plant to "catch up" rapidly.

Great to be stoned!

Frankly ....

Ive been doing this for a while...

ANd I dont remember one grow using verm and perlite that came out good....

I grow some in two liters....

Here is what I suggest...


Go buy some miracle grow organic soil.... by volume 50 % perlite....

1 tablespoon per gallon dolomitic lime.....

feed pbp and Liquid karma.....

Thats what Im doing and my plants are fab....


as far as your trubs....

too much verm.... too wet....


I managed to find a pic in 2 liters....

notice the leaf tips ended up still pristine....




same clone in 2 gallons....

Wow, that is surprising those came out of mircle grow soil? I have never heard of anyone getting good results with that stuff. But hey it is called "miricle" so I guess it is possible.

If I were you I would start all over with these plants you have tried everything and nothing is working and you cannot see why? Well I think it is because you have thrown everything but the kitchen sink at these plants and but doing that your causing more trouble.

So first go get some soil any old potting mix will do try to find something that does not contain any ferts (the numbers on the bags) transplant all of them out of those clear containers into something that keeps the light from the roots...since you have the perlite already go ahead and mix the potting soil with 25% perlite and 75 % potting soil.

Now when your repotting do your best to get as much of the old soil and stuff off the roots and maybe break off 1/4 inch of roots from the bottom.

Then water then with nothing and I mean nothing but PH balanced water at anywhere from 6.3-6.5. Give them at least 2 weeks of that (new soil will supply everything they need for first 2 weeks) and see what happens.

If you continue to keep messing with them you will surely kill them or stress them to the point of hermies when you do flower.

I am betting that once you put them into soil with out all that light getting in to the roots and all that vermiculate in there to hold the water your going to see a world of difference and you will find that it was nothing more that, causing you all these problems.

For it to be a defiency of something it would have to be pretty bad for it to cause that kind of damage that quickly. Plus your PH is not that far out of range if that to be causing damages like that.

Well for one thing, don't expect the yellow leaves to get better, cause they are not, just watch the green ones, that is the barometer. This could take a week to notice differences you mentioned.

SOG: the verm/perl was just to start seedlings and I had used it before with no problems before transplanting outside. I was eventually shooting for a soiless mix that stays a little more moist once I have my mother's picked out, (this mix dries out very fast) they will all be going into a DWC soon. The mix is exactly 50/50 I know for a fact there is not to much vermiculite, you just can't see cause the perlite cause the vermiculite stains the side of the bottle plus the root balls pull and hold the perlite pretty solid.

BV: I don't smoke =/. Just really enjoy growing. I tried that left it for a week or two and got nothing

Everyone in general: It's not like they have gone through huge fluctuations and I haven't given them time to adjust. I would feed them something slightly stronger let them adjust for a week or two and nothing, still got yellowing of low fan leaves from main stem. Looked like N def. Upped the concentration a bit, still got same thing after letting them sit for about a week and a half this time it looked like Mag def. Upped again, let adjust for a week and a half (3 waterings) continued to slowly progress up plant, looked like Mag def with a bit of nute burn. Flushed with 3x container size of PH adjusted RO water, fed with 9/3 mix been about a week now and it hasn't gotten better. Those pics are about 1 week old right before the flush. =/

ANd ..... your comments on the light and roots are nonsense.....

And I do agree with this. I wanted to see when the earliest the root balls maxed out so I could know when the earliest I could transplant was. They are under floros, floros are week. =/ I've watched the roots and they are all nice and healthy, shiny and white, no problems. =)

I was worried a tad about hermies cause I've seen it happen before but I don't want to start over I know these plants can take alot fo abuse and still come out on top. I can try putting them in a bubbler and see how they turn out, some of my other plants where doing the same thing but look fine once I get them in the water.

Sigh, still frustrating I just wish I knew what was going on.

Anyone got anything else, keep it coming, it's all considered and appreciated.

You can see magnesium def in this picture easily. Yellow leaf but green veins and the margins are burning and curling upward.

I forgot to mention before that once a mag def occurs, it is difficult to correct especially if it is in the midpoint of the grow.

Try a foliar spray on one plant using 1 teaspoon epsom to a quart. Spray both sides of the leaves.

Full strength curative rate for mag def: 2 teaspoons per gallon epsom as a drench or 1 tablespoon per quart sprayed on both sides of the leaves.

You should be at least 12ml pbp and 4 ml cal mag plus. Using weaker was probably to blame for your problems starting and now snowballing.

Another thing to try is raise ph slightly higher. This will increase mag uptake. Not too high or you will reduce micros and p.

I think in future grows you should try a mix of 50/50 peatmoss and perlite. This is a Cornell University idea. Dolomite lime will have to be added because of the peats acidity. Cal mag plus will have to be reduced because less is needed while the lime is fresh.

 

[Guest]

a 50/50 mix of perlite and vermiculite is not MY recommended medium. I never had luck with a hydropinic medium, to much adjusting and ammending. Go soilw ith dolomite and your flustrations will ease 10 fold.

 

[Blackvelvet]

Why can't you repot one size larger using some better soilless media like peatmoss plus perlite? That would be a good time for dolomite lime and boost your mag levels.
