To prune or not to prune???

[The Alchemist]

My plant as many pf ye will now know is in poor health and has been for some time.

I planned to put it in to flowering last week but said i'd wait till i have the problem fixed. I still can't figure out what it is. My plant is displaying signs of nitrogen deficiency, phosphorus deficiency and over ferting(brown spots appearing on the certain leaves) so i reall can't understand whats going wrong. Also there are a few black spots on a couple of leaves.

What i want to know is should i prune of the completely yellow leaves so that the plant can put all its energy intogetting healthy and not keeping dying leaves alive.I wanna know this cos over the next few days i'm going to try and fix this problem through experimentation and i don't want any of its energy wasted.

However i also think that maybe if i remove the yellow leaves that then the yellowing will only spread to other green leaves instead of sucking the yelow leaves bone dry(which has happened to a few of them.

Try a lower ph like 6.

got any picks?

Id let the leaves that are def not comin back to cannibalize themselves from the plant.

Try to correct your nute def problem for rest and future.

Best of luck!

It will pay divedends to get her healthy prior to cloning or flowering.

If it's not brown dry and crispy - the plant can still draw back some of the energy in yellowing leafs - so my rule in this case is remove only what the plant shows you it dosen't need. It's a better judge than you or I.

First grow?

Got a picture?

Lots of simple things can be a stumbleing block about now, and the first is under and overwatering - that will look like every defeciency in the book.

Eliminate the simple stuff first.

Ya its my first grow, they've been in veg for two months and every thing was going pretty fine, a few minor problems untill two weeks ago. I've no pics at the moment as i don't have my camera but i'll try to get some tomorrow.I'm using bio-bizz butes and some people say that they are pretty weak nutes so i'm thinking it could be lack of nutes, but the brown and black specks confuse me. I let the pots get light befor i water so i don't think its over or underwatering.

I'm really stumped by this, i've never seen or come across a plant with all these problems and i've done a lot of reading.

Sproutco : Lowering my ph to 6 will only lock out other nutrients that the plant needs at the moment i'm not willing to risk causing it anymore harm.

I like hearing the light pots - over attentive disorder is a problem with new growers.

Sprout is right about the 6.0-6.2 ish range - (atta boy sprout) if your high,bring it on down a tic or two. Are you testing PH now?
Accuratly? - (them dam stick in the soil testers are no help at all)

What soil and additives?

any pearlite? Pearlite is good. opens and lightens the soil and makes the plant expand out to find the nutes.

transplanted lately? That might be your first step as soon as it's ready to water - up pot it and loosen the roots. Sometimes a look at the roots will help in the diagnosis root bound and insufficent roots will kinda look the same too - insufficent root mass for the above ground part

The soil ph on the bag says between 6.2-6.4, anything i add is always around the 6.5 mark and my run off is generally the same.I thught 6.5 was the ideal rate acocording to all the charts all the nutrients can be taken by the plant at this ph.

Ya i'm thinking a transplant might be necessary just to give them new soil in case theres been a build up of salts or something from the epsom but i haven't done it yet. My plants shouldn't be root bound cos i'm using bigger containers then many other grow that i have seen.

 

[The Alchemist]

btw there is perlite in the soil aswell. I'm using All-mix soil. It comes well recommended from a lot of growers!

Great you've done a lot of homework and that will make this easier - the only problem I see in the above info is - root development. Cannabis sends runners out and down and then surrounds itself when in a pot - this can be a problem. it leaves a hole with perfectly good soil and low density roots. I want dense, thick and healthy roots from wall to wall. My way, they don't have a choice.

Personally I always start small and transplant often. (see photo) - it's at least a week from transplanting then only to a 24 oz cup

An 8 or 10 os styro cup is home for 2 or 3 weeks then a 24 oz, then 1/2 gallon the 2 gallon and by the time we get to flowering, it is a solid healthy mass of roots.

If you start in a large pot with a small plant, you get a lot of empty space and problems growing.

I would definatly check the roots -

opps

How big of a pot are they in?

(PLEEEEEASE don't say 5 gallons)


if the roots are thin and stringy, ya gotta be really careful not to break them, remove the root free dirt - condense the roots a little - little soil - little roots - little soil. If it's lacking - grab the next size smaller pot and downsize - she will recover easier - if we don't shock her into flowering.

She isn't going to like it, but i know of no other way to fix it.


If ya pop the roots out and they are solid and firm - then go ahead and transplant but ya gotta know what's going on "down stairs"

check back


I drop my ph down between 5.9 and 6.3 or 4 every watering - I also add 1 tsp of dolomite lime per gallon of soil - this will help buffer the ph a little.
Never used Bio-Bizz so no help there.
I'm growing with FoxFarms OF soil and a pretty varied nute assortment Based with Foxfarms and guano teas, kelp juice, fish juice, PK 13-14 (this one is new to me), - Ohh and my secret weapon, bubble hash water

Captain JamesTKirk and last night i checked were my plants rootbound and to my suprise they were so i transplanted them both into bigger pots(one into a mayonnaise bucket the other into a little rubish bin, i made sure to wash them and used an antibacterial cleaning agent) When i checked on them this morning they had grown about an inch or so, the biggest growth spurt i've ve seen them do.
Thanks so much for your help.I never read that thing about moving your plants up in pot size slowly(or if i did it didn't register) and i didn't realise that being rootbound would cause all these problems. I now swear by Root-Juice by Bio-Bizz cos one of my plants is not too big but still had a massive root structure.
Thanks for the help

cool


Let her run for 10 days to 2 weeks. Rest, recover and kick in the afterburners.

Prolly wana up pot one more time after that, a week or so extra then flower. She will reward ya well now.

every day or two, trim off one or two bottom branches - might wana clone them. she might be a keeper, ya never know

as you were

One to beam up.
