Dieing Leaves

[New Holland]

I'm growing in Coco. 6 weeks in Veg. COGr Nutes. ph=5.8. Plants are generally healthy, really green with plenty of new growth.

 

I'm a bit concerened because some of the OLDER leaves are showing signs similar to nute deficiancy. They are turning brown and crumbly on the edges. It's only on the leaves that were from the original mother plants when I took clones.

 

What am I doing wrong?. Should I be worried?

what strength are you mixing your nutes?

since you are growing in coco, im assuming your growing in pots like i do with my grows and i notice that problem all the time, especially later in flowering all i have been able to boil it down to is that when the plant gets rootbound, it starts dropping off the older growth

[New Holland]

Gee, don't you guys ever sleep?. I wasn't expecting a reply untill tomorrow!.

 

Could be root bound problems. They're 12" tall in pots about twice the size of a scooner. Ran out of money, so I've only just bought the big pots and coco.

 

I've been mixing my nutes at 55mls per 8 litres of water. I don't know what the EC is but the ph is 5.8.

nobody ever sleeps here, NEVER I TELL YOU!!

 

i can relate to the money problems

 

55mls is high aye....wait....is that for both parts?

 

or is it 55mls Part A/55mls Part B?

i find that with coco the size of the plant dictates the pot size you need ie. if you want a 2ft x 2ft size plant, you ATLEAST need a pot of the same size to prevent the plants getting too rootbound and from what i have seen having a pot of an equal size doesnt mean you wont get rootbound, it will only make it take longer to happen

[Bundy]

i concur

 

as far as i'm concerned, if the half of the plant above ground doesn't look like it can fit in the pot then neither can the roots

 

they must be free i tell you...FREE!

Bundy: 55mls A then 55mls B. That's what it says on the bottle. Its ph buffered, when I mix it at that strength the ph is smack on 5.8. If I was mixing it to strong the ph would be to acidic.

 

Wantda: They didn't seem to be root bound when I took them out of the smaller pots. I've trimed of all the dead shit, and I haven't seen any new dead stuff.

That might be what it says on the bottle it doesn't mean it's right for your plants, each strain varies in the strength of nutes it can take up/handle. The best thing you can do for yourself is get a TDS meter that displays ppm that way you know exactly what the strength of your mix is and adjust it for the needs of your plant.
