Mg def..?

[kenned]

hi everybody

I'm like 2 weeks into flower, and my plants are having some serious problems!
it has startet som time ago, and i thought it was because I gave them to much nutrients. But instead it began to look like they are in need og Mg.

But I'm still not sure, so i just wanted to check with you.

It's a sort called dragon haze, (some indica/sativa strain)
I grow in soil, under a 250w hps.
My pots are 3,6 liters and my fertilizer I used biogrow in veg and since last week Top Max and Bio-bloom, all from Bio-bizz..

welll, heres some pics, hope you can tell me whats wrong...

well, thats them, hope you can help me..

A little pic of my flowering ex-moder, quit small, but nice crystals already..

have fun,
Kenned

The last pic is a real beauty mate!,but im not really too sure with the first plant.
Some of my leaves turn yellowy at the very bottom of the plant accasionally but that doesnt really bother me,but im not sure what them spots are, are they getting good air circulation and clean air?

I think theyll be fine but, id wait for someone elses reply and get expert advice. They
always helped me so.

Good luck.....lovely last pic too!!!

What are the chances that they are rootbound? Looks like that, PH problems or a lockout from your water IMO...

green michine-- thanks alot.. It my favorite plant myself..

Sandman--- I must say, I'm not that good at english.
What does it mean to be rootbound?
I've been reading MyNameStitch's "The Complete guide.." And what I can understand from that, it might be a good idea to flush the pots with alot of water, to get all fertilizer out of the soil, and then start fertilizing again...

what do you guys think about that?

Its definitely Mg problem. Notice how it is only effecting the older leaves while the younger ones are perfectly fine. Mg will transfer from older parts of the plant into the newer parts b/c of lack of fresh Mg to absorb.


Test some of your water runoff for Ph. Ph is a leading cause of problems. Even when nutrients are there they may be restricted due to a ph problem.

if useing bioo bizz get some Plant amp by cutting edge and there mg its OMAR orgainc not the mg but the cal..When i use those with the the bioo i have got really big mass and no problems.. bioo needs some cal for sure are u willl see it the whole time i f i didnt use the mg i would get mg problems ass well thats why i use it.. it try to stay organic but some times u need a little help ... good luck and looks good..


forget to say if u us the plant amp u can use it as a Ph down thats my serect organic down if u use it at full stenght ur ph will go way down..and there Mg is get...i use to use calmg form BCare but it has alot of N which u dont need in flower..so rock on

hi kenned!

when growing in soil usually Mg and Ca are not an issue, unless you are using reverse osmotic (RO) water, water that does not contain ny MG and any Ca.

As MTF-Sandman did, I would suggest root bound: the pot in which the plant is growing is probably too small and the soil does not carry enough nutes for such a big (relatively speacking) plant.
The fact that your plant shows signs of what I'd think could be a nitrogen and potassium deficiencies point me in that direction.

PH: when growing in soil ph problems are not so common. The soil is a great ph buffer and changing its ph values requires the use of a lot of high (or low) ph water, over fert, etc.
If you did not mess up with water ph, I'll suggest to concentrate on other issues.

Hope this may help.

well, thanks alot for the answers.
I was'nt quit sure what to do, so I took 3 of the most "attacked" plants, and cut all outer roots of them, and put in new soil... like this:

The 2 at least "attacked" plants, I flushed with alot of water in the shower.

Not quit sure wether it is good or bad things i put my plants to, but hope for the best.

it here is anything I might do to improve, just say so...!
