yellow fan leaves @ bottom

[jchap]

is it normal as it's in 1 month flower?

or maybe the soil is too wet?

pls you help is needed

[jchap]

my last plant didn't do this, but this plant has alot more bud sites

[denial102]

thats not mold i see is it? :(

Might just be my vision kinda boggly with this HPS on next to me :-)

Although the plant I had usually gets bigger before the lower leaves dry out and fall off I'd consider it normal if you can account for nutes, mold, insects, etc.

Good luck with it homes, :thumbsup:


Peace,
Denial

PS: I have read many grow logs where plants inexplicably start dropping lower leaves and putting their energy into new leaves, have your plants been stressed at all?

[jchap]

no mold or insects

it's got 4 weeks left and hasn't been stressed

thnx for quick reply

anyone else know?

hopefully it's the plant just drawing needed energy due to to many bud sites

[jchap]

doing some research it could be nitrogen or magnezium deficiency

i'll see what you guys reckon first

maybe some epsom salts will help

unless it's normal this stage of flowering

hey dude, no probs, I know it's normal for the lower leaves to fall off for some strains during flowering, if it is just a few you should be OK, most growers will say keep an eye on it and see how things go, if it gets worse consider the salts.

Peace,
Denial

[jchap]

gonna try a little fish blood and bone

just a little to see if any improvement

[Wobster]

Careful with epsom salts. It's easy to overdo an then lock out everything else with a salt build up. Looks like N def.

[zebulon]

What nutes are you currently using???

[sublime27]

I had the same issue that started right about the time you are now, I dont know for sure the reasons as it could be many but the nutes generally have less nitrogen for flowering which looks like the case. IMHO, if it is only on the lower leaves and all you see is the n def. i wouldnt worry about it too much. It looks really good though and i wouldnt change too much. :thumbsup:

[jchap]

bio-gro and bio-bloom
i read that N deficiency is good during last stages of flowering, dunno if it's true tho

the fan leaves above are starting to turn yellow!

i just didn't see it in last my last 2 grows, same strain and everything

but this plant has more bud sites, alot more :hippy:

That's exactly why you're seeing it more pronounced this time. It is indeed normal for most plants to yellow and have leaves fall off during the later stages of flowering. Flowering nutrients have much higher P and K numbers than a vegetative, and have much less N. Besides the plant needing less N during flowering, allowing the plant to consume it's reserves allows the quality of your final product to be better (N in buds = harsh smoke).

cheers for the info

i'll update in a couple of days

[rastaman79]

It looks ok man,poss mag def,but your prob more than half way thru your flowering and you`d be harvesting before you could correct it in soil IMO,nitroegen def is totally natural late in flower and you really want to be seeing it,as mentioned above you dont want your buds full of N when you harvest,dont forget to flush for about 10 days with straight ph`d water prior to harvest,good luck, RM.Peace

Classic textbook magnesium deficiency caused by a too-small pot of too-wet soil.
Foliar with epsom salts at 1/4teaspoon per gallon with a drop of dish soap in the spray bottle.
Re-pot into a larger pot.
Water modestly in the future- don't allow the plant to wilt, but the soil should be allowed to dry a bit between waterings.

you right the plant did wilt a couple of times due to underwatering

will try the foliar with epsom and repot

will google dish soap

more leaves going yellow

[jchap]

how much epsom salts do i add per litre of water

and do i just spray the yellow leaves avoiding the bud sites?

....leaves to go supermarket to purchase epsom salts ......

dish soap?

will this mag def murder my lady?

thnx for the info

are you also british?

[jchap]

4.5 litres per gallon(uk)

pics of before foliar and amount of epsom added in litre

after pics in a week or so

skipped the dish soap didn't know what it was?

[jchap]

dissolved the epsom in warm water and sprayed over whole plant above and under leaves

how often should i do the above?
should i add some epsom salts to the feed?
how can i avoid mag def in the future? (tap water = high calcium = mag lock out)

[stinkyattic]

Don't add any in the feed since you may already have other soil problems.
You can spray that mixture a couple times a week.
Now you need to put the plant in a larger pot with fresh soil and not water so heavily.

[jchap]

thankyou stinkyattic

will post photos of results in a couple o days :thumbsup:

[jchap]

did you mean washing up liquid when you mentioned dish soap (fairy liquid):stoned:

[screwthemods]

Dish soap = liquid soap (used for washing dishes in the sink). I would guess that "washing up liquid" is the same as "dish soap"

[stinkyattic]

hello again, I was wondering how long it would take you to return. username #5...

[jchap]

2 days later it seems to have slowed down, i hope

[jchap]

white rhinos ready for 12/12

[stinkyattic]

Looking good; I don't see the nodes alternating yet though. You can give them some more time before flowering and it will be better- they will be sexually mature then.

[jchap]

im in a hurry if i dont force flower now i'll be dopeless for a month lol

[jchap]

happy days, 3 of 4 of the rhinos turned out to be female :stoned:

[jchap]

the yellowing seems to have slowed but it still happening

nearly all the fan leaves have turned yellow and dropped off

more pics soon outa batteries

all thats really left is bud

[jchap]

started to flush her 15 days to go, but i might harvest sooner incase the bud goes all yellow

the buds are alot smaller because of this mag def

here are some pics

[stinkyattic]

That plant is nowhere near ready to harvest. You have 2-3 weeks before you should even think of it.
The buds are small because the plant is not nearly done, and that pot is WAY too small to support any sort of mass. Re-pot immediatley into at least a 3 gal pot and go back to feeding your bloom fert for another 1-2 weeks.

ok i will do as you say
i thought it was nearly ready cause the pistels are nearly 50% brown

i'll buy a new pot and i'll start ferts again

thanks for the wise words

[stinkyattic]

Trichomes are the small crystals on the calyxes and must be viewed under maginfication. When they are 5-20% amber (depending upon the high you desire), the plants are ripe.
There is a chart in the link in my sig that shows a graphic of this.

[jchap]

will the yellowing affect the buds?

although the yellowing has slowed it's still creeping up the plant slowly

i look forward to comparing photos in 2-3 weeks to see the difference

thnx again for saving her :)

[stinkyattic]

It's creeping up because you are flushing too early and the pots are too small. You actually WANT the plant to be yellowing some at harvest; harsh flavor comes from excessive chlorophyll (green pigment).

[jchap]

latest pics

yellowing is worrying me now, need i be?

i hope they ain't orbs in the first pic :jawdropper:

weird face in the telly

[jchap]

i hope the top ends up like my last plant

[jchap]

should i be worried about the yellowing?

[jchap]

latest pics

alot of the leaves have dropped off

comments welcome :)

[jchap]

white rhinos flowering :D

[jchap]

no adverse effects to the buds

so if you get yellowing late in flower .... dont panic

here she is :D

[stinkyattic]

The buds look good. They would have been larger if you'd given ample pot space though... next time! :D
