well I don't think she has nitrogen def. because the youngest leaves have brown leaf tips(you can hardly see them), but who knows. I gave her some flowering ferts 10-54-10+mg,zn(shultz, bloom+) after I moved her. from 12h direct sunlight(field) into woods where she gets aprox. 4 h of direct sunlight. Seaweed is the main thing but also some chiken poop. I don't have a system for feeding. 12/12 should at septemver 20. over here, but the plant should realise that the days are getting shorter and she should start flowering earlier?

 

[HerbKnight]

ok, I was in a hurry yesterday. I haven't checked the ph. I think shes started to flower now, but its not good to give veg food right now?I've heard that that slows flowering.If you say that she has N def. on the pic I'm pretty sure she has that now also, but is it normal that most of the bottom leaves have those large brown spots on them?

 

[MynameStitch]

brown leaves can be left over from what an itrogen deficiencty hows if its slow nitrogen deficiency problem

a sparse problem

stay away from those ferts your using, that stuff is for trees or other plants that require high amounts of phoshprus

you will cause more problems if you continute to use that nutrient

get something under the 20 mark and stay below 15 or 10 for nitrogen

can you get me another picture of your plant?

 

[DurbanPoison]

Curling UP and Down? What's this?



No nutes, just transplanted a few days ago to pot 2x larger. Using Fox Farm ocean forest 3:1 Perlite mix. Feeding plain ph7 water.

mid-upper 70'sF and 40-50%RH.

 

[HerbKnight]

here are those sick leaves:



and here is the plant:





Here is a plant that had the ''...bloom+'' food:









This week should be the harvest week.?(all pics are taken on saturday)

 

[MynameStitch]

durban what lighting are you using on your plant and how often you are watering?

the leaves look like they have died and dryed up, anyway it is a nitrogen problem, since the bnrown leaves are only on the affected yellow leaves, that would tell me thats whats left over after the leaves have died....... get some nitrogen into those gals

flowering they need ntirogen but not to much of it or it will slow down flowering

what nutes you using or going to use?

how long you been flowering? it looks like it needs more time to flower than that....... what strain are they?

if you do harvest, which it highly doubts it looks like its ready but if you do donty do anything just make sure next time you see this problem you know its nitrogen problem

 

[HerbKnight]

that last pic is of that plant:

yes,she looks quite raw.She also had the killer mix. flowering nutes.and she is 0,5m tall
Here's a better pic of that big plants flowers, (aprox. 2,5m tall):


top colas have (pretty much)all their hairs turned brown.

I don't know the strain and I'm not sure how long their being flowering because they were already preflowering(less then 2 months?). But when should I harvest her, when 3/4 of hairs are turned brown?Was there something about trichomes changing colour?

 

[MynameStitch]

do not go by the hairs, going by the color of the tricomes is better, i have tried both and the color of the trichomes is what you want,

take a microscope and check the colors of them, i used to have a chart i will have to dig it up on one of my backup cd's

you want the heads of the trichomes to be cloudy, some amber,

cloudy gives you couch lock and amber head high, if you have mixed you get both 50/50 mix

you will have to take the microscope and take the leave and check it and take a look at he heads of the tricomes, they look like little mushrooms




the pistals is not what gives you the high, its the tricomes and the resin it produces the little white things that is on the plant, the sugar looking stuff

that last picture you posted i can see some trichs just from that picture, they are in the lower left corner, they are white they are on the leaves,i still say she has some time to go, but if you wanna harvest her i really think its going to be a waste,

anyone else wanna chime in on this plant? harvest or no harvest?

but istill say you have a little bit more time to go......

preflowers does not count as flowering time, flowering time starts about a wek after 12/12 has started, they just dont start flowering right when the first few days of light has diminised

why do you think seed venders give lower flowering times on there plant? because most people start flowering times the first day they flip to 12/12

cannabis doesnt switch over night, takes around a week, which is why i reccomend everyone i give advice to, do not switch to bloom nutrients the first few days of flowering, wait a week for indica strains and 2 weeks max for sativa dominant strains

this stops nitrogen problems in flowering by doin that, why? because even though the plant is in 12/12 its still in veg for the ifirst few days, and releasing the proper chemicals inside to switch to bloom cycle takes a bit

so iby using bloom ferts when the ifrst week of flowering your depriving your plant of veg nutrients that it still needs because its not quite into bloom yet

 

[HerbKnight]

I know the flowering stuff( exept switching to flowering nutes, made that mistake)
it's basicly my first grow so I didn't knew when she switched from pre-flowering to flowering, she started flowering WAY before the 12/12 witch is on the 25. of sept. over here.
Did you ment this:


I'm afraid that I'm not able to see the trichs changing colour
I don't WANT to harvest it right now, just thought it might be on this week, but how many weeks then,top?

Big thanks for the help so far

 

[MynameStitch]

ya, ive seen that one, most people dont go by that one anymore, they go by the trichcome picture, i think maddog is the one who made the photo the one with the trichcomes in the picture, that one above you cant go by because pistils can sometimes die early depending on when they pre flowered or if they did

get a microscope and see the trich's you cant tell by the naked eye,

trust me ive done both methods several times and the best smoke is waiting for the trichs to change color, its a huge difference

but do it the way you see fit, just trying togive you advice

 

[HerbKnight]

yes, ive noticed that the pistils are quite brown, but the trichomes are totaly white.

But do I MUST, get a milder mix of flowering nutes?What happens if a plant gets too much P?
is there something wrong whit those plants that r in late flowering?(the'r strain should be some kind of hemp(exept the one in pot), but what about the trichomes on them?)
Why i ask this because getting a better fert. means 6h of traveling by trains and buses.It's like we have the biggest flower and garden market in the baltics and there's like 5billion different flowers and pots but 7 different kind of nutes and they all pretty much say: good for veg. and flower. nothing about NPK.And NO organic ferts for blooming, NOWERE in the country

Is 4-1-2(it's chiken poop) good for getting rid of the N def.

 

[MynameStitch]

ok tell me what you have acess to and i can tell you if you can use it or not, remember it doesnt take great nutrients to grow good cannabis

just some that are to high in npk are not good

anything that us over 20 is NO good and should be stayed away from

what county are you from?

 

[mriko]

yay, my turn to ask for some advise and help from you MynameStitch !

I have tow Himalaya Gold (GH seeds) growing out in pot. Been nice si far, but since the flowering as started the fan leaves are turning yellow at fast rate. The plant receive their weekly dose of Fish Mix for nitrogen, but still going yellow (I even wonedr if it does not fasten the yellowing !). Some leaves also have tiny withish spots.

On one of the plants also, tips of upper fan leaves are going yellow as well.

It's the very first time this happens to me. Yellowing of fan leaves is normal for sure, but never it happened so early and going so fastly (But I suspect some genetic impoverishment of the strain, through too much stabilizing and inbreeding).
Any idea about what's happening ?

thanks in advance !

here's the pics :







Irie !

 

[MynameStitch]

you may have some thrips or mites on your plant, the spotting, look under your leaves with a magnifying glass to see if you can see the mites,

thrips look like a louse... like a sesseme seed.....

as for the yellowing, that is a nitrogen deficiency, how often are you giving it fish emulsion and how much?
shes in flowering, almost all strains require different amount of nutrients,did you switch over to bloom nutrients to soon? or is your bloom low or zip in nitrogen?

how often you give her fishemulsion and how much is a big importance, but you dont want to give to much or it slows down the flowering process

 

[HerbKnight]

10-15-10 or 8-14-9? well I bought the last one It was for african violets, feed every time when water, can I make a stronger mix? because african violets r much smaller then my plant.

 

[MynameStitch]

how mujch is it saying to use on the back?

do not feed every water if you water more than once a week

 

[HerbKnight]

7 drops per quarter of gallon. 14 drops --''-- for feeding 1 in month.

Glad your back

 

[MynameStitch]

what brand of food is this?

when you water do you use gallon size?

 

[HerbKnight]

no, liters, 1 liter 7 or 14 drops. its schultz, again.

 

[mriko]

thanks for tips stich! Can't see any eggs or bugs apart from the usual flying ants which get stuck in the resin.

for fish juice, I give about once a week, about 2/3 of a cap in 1.5liters divided among the two plants. Doesn't slow the yellowing at all, leaves ares till dropping. Maybe should give a bit more fish? Or could be also from the plant itself ? seeds were not straight from the breeder, were inbred several times before i put my hands on it.

For blooming they receive Plagron Alga-flo, Bat guano, sea-waterbased SF94 and Top Max, and Shilajeet (contains humic acid). Agh, just realised the Alga Flo is a PK 13-14, with no nitrogen at all ! Also I use a new brand, Fish-Mix. Before I had some SensiSeed Visemulsie which had been cured for more than ten years. Obviously hte Fish-Mix is much weaker...
