why do my plants lose there leaf is it normal???

hi every time i grow a plant during flowering time they ether lose there leaf or the leaves go bad making my plants look sick does anyone else have this problem?

can a plant still grow the buds even tho its losing its own leaf?

Is it losing all of their leaves?

Got pictures?

Is it losing all of their leaves?

Got pictures?

i got previous plants in my sig http://forum.grassci...get-grow-2.html was almost bald and the weed was horrible so bad i binned it all

the one i just harvested http://forum.grassci...-ready-yet.html the leaves went bad but it is an good smoke

the one i have now is just starting to lose its leaf http://forum.grassci...-bent-over.html

So, what are you using for flowering fertilizer and the N content?
Some plants/strains the leaves will yellow and die during flowering and this may be normal for you.
For better odor/taste you need to flush real well and dry/cure them properly. This could take 3-4 weeks and sometimes will smell like grass until cured in jars.

Some strains apparently defoliate on their own. I notice with the strain I'm growing, the plant begins to shed leaves that are still healthy. My fanleaves begin to turn light green and fall off at the slightest touch. I believe that my plant is cutting the leaf off and then the leaf begins to show deficiencies.

I suppose it's a matter of understanding the strain you're growing. If my fanleaves were dying and had strong foundations, then I would question whether or not I'm providing everything they need. Because the foundation of the leaf becomes weak while the leaf is still healthy, leads me to believe that the plant is doing what it's supposed to do.

Basically, it's my belief that if the leaf is turning light and the plant isn't shedding it, then the plant is probably short on energy and needs what that leaf is providing. If the plant begins shedding leaves that are still healthy, then it probably doesn't need the energy that is stored in those leaves.

I could be wrong, this is just an observation.

I don't get it maybe I'm just lucky and my room is a perfect environment but I've never had to cure. By the fifth day hanging they're all smokable , they end up curing while waiting for me to smoke em but I've never done it gone through a whole cure. I think in people haste to dry as fast as possible they ruin the herbs.
On my plants I'm week three of flower and I'm picking dead leads from the lower parts and the inside of the plants on a daily basis but it's totally natural. As summer gets further along the nights get longer and the plants know that the end of their life cycle is coming so they flower and try to carry on their genetics.

I'm using baby bio (high in N) for veg

after the first 2 weeks of hairs Tomorite (high in P & K) for flowering

i was thinking of mixing them since the tomorite is low in N but idk if thats a good idea

i harvested a plant about 2 weeks ago i cant help myself so anyways dried it for like 6 days hanged on a hamster cage no fan or nothing and there was no smell ether tried smoking it yeah it got me a lil high but the taste omg was the worst taste ever it was simular to smoking leaf

after week 2 i put it in a jar and now every day that goes by the buds are starting to smell stronger and also tried it its less harsh burns good in a pure spliff (no cigarette) it gets me high as fuk but it still dont taste like skunk i buy from my friend

hey glad to see your grow which also has yellow leaves i thought i was the only one usually when i see flowering plants on here they a nice green color mine always turn yellow maybe its the feed we using??

I wouldnt recommend mixing the two at all. First check all your pH levels to make sure there are no lockouts. If need be slightly up the dosage of flower nutes under your normal feeding schedule and see if there is a difference.

Plants will shed leaves lower on the plant in order to maximize energy. Not only does it all for better circulation in your case but it allows the top foliage which is closer to the light to attain maximum production and growth due to the recycled nutes they take from the leaves they shed.

It could possibly just be a lack of nutrient supplement within your soil/hydro. I have noticed that many different plants will recycle N/P/K from their leaves in order to maximize flower growth. You can check this very easily by seeing if some of the green color returns to the leaves right after feeding and first thing in the morning when the light is out/on. They tend to synthesize new chlorophyll at these times on the leaves that look dead/ yellow/ etc.

i dont know how to check ph and am using soil


heres the labels for the food

Baby Bio:

Tomorite

you might wanna zoom in on ether link provided above its easy open the link then hold ctrl and roll your mouse wheel or use +/- on num pad

I still don't know what's a good way to test the soils ph either and this is my tenth grow in this spot somewhere around ten anyway. For ye first two years I didn't even know what ph was. Then someone mentioned it to me and I've been fucked in the head over it ever since. I just try and make sure the ph if anything going in stays between six and seven. No problems seem to happen when I keep it to that. Another thing you can do is add lime to the soil it will make sure the ph doesn't drop too low. Not sure if it brings down a high ph though.

i maybe ole fashioned but havent a clue myself all i do is plant a germinated seed in multi purpose compost feed it occasionally and just hope for the best never worried about PH with my garden outside cannabis is just a plant cant be too difficult can it

The yellowing is normal in flowering. I find it start about a month into flowering. It's the plants normal way of shedding unneeded leaves. If the are alot and in your opinion it sounds like it was. I would say they suffered from a deficiency and lockout. I would flush them just prior to flowering then start with flowering and add a small about of a nitrogen rich food. Marijuana continues to veg for two weeks after placed in flowering. Keep feeding nitrogen at a high level until calyx begin to form then increase p.

Drying and curing are two different things. After a week or so drying yeah it will be smokable, but curing it in a jar will bring out the flavour even more.

Anyway in response to the topic, unless it is a massive shedding of leaves then yes it is normal, the plant uses up energy from some of it's sun leaves to help it through flowering.

ive only just started growing good seed for about a year i guess i just need practice. i did have some practice before then but didnt work out it was bad seed


cant afford my 400w to be on all day so its always on 12/12, please bare in mind i never have problems during veg just half way flowering i got a problem with.

ive only grew one plant thats ok NYC diesel she dont taste nice its like smoking leaf BUT shes getting me high man i prefer smoking that to the hash i just bought off a friend it must be descent shit just dont taste or smell nice

strains and even a phenotype variance can have some odd behavior if you are used to otherwise...

the fans leaves yellowing and falling off had me going nuts first time...lucky me though, I had access to water testing labs. Nutes were fine, no bugs, no pest, no germ...and otherwise some nice bud production going, big juicy fruity goodness on a stalk...then a wise old hippy let me in on this bit of knowledge...'its just how some herb flowers' and it's held true.

On the PH question. I am a hydro grower and don't know a lot about soil but,

isn't their a ph meter that you stick in the soil to get a ph reading. If not, can you ph your run off water?
