[attachmentid=88666][attachmentid=88667][attachmentid=88668][attachmentid=88669]hey this is my first grow and have had quite a few problems and cant seam to sort it out my big 5 ft plants still have yellowing leafs but only seam to be at the bottom/middle (yellow lef pics) and my smaller plants witch are shivers have a bit of yellow down each side of the leafs and feel rough to touch if any1 has any idears on what i can do to sort this out that would be great thanx.also these plants are growing outside in soil in my greenhouse.

could you fill out your profile or give is some more details please?

sorta
inddor/outdoor
nutes used? & how much??
are they flowering? if so by how long??
if indoors, what ventilation?

etc etc

the more info we have the better we can help

sort = well the yellow leaved ones are mixed outdoor seeds and the others are shiver's
inddor/outdoor = growing outdoor in my greenhouse
nutes used? & how much?? = im useing B'cuzZ soil nutrition and putting 5 mill of each a and b in to 5 leters of water.
are they flowering? if so by how long?? well i think they will start to flower soon but not to sure as in greenhouse.
if indoors, what ventilation? green house :-)

have you given them any epsom salts yet?
Looks suspiciously like an mg deficiency tbh

are you in a hardwater area? plenty of chalk etc? It could be locking the magnesium out???

the ones with the yellow leafs i gave epsom salts about a month ago and the other ones i gave epsom salts to yesterday and im not sure if i live in a hard water area but everything ive tryed sence i started growing hasnt worked so maby i do :-(

I could be wrong but i imagine tis flowering nitrogen blues

hummm me not understand that ????????????????????/

When your plant goes into flowering, i do believe it stops taking up so much nitrogen, because it isnt in very high demand during flowering, whereas it is in higher demand during the vegetative stage.
Its responsible for making your plant green and bushy, so when uptake decreases the leaves turn yellow and drop off. This is just a possibility mind, i cant be completerly sure

Looks like a lack of nitrogen to me

Owd

ta owd
was a toss up between the 2



"aah you need glasses",says owd... "bugger that owd, old age? bah... ok, where's me lighter?"....
"fuckit" says owd, "the bugger's blind... it's right in front o him!"

.If you are a blind old bugger then I am aswell

If it aint got dark veins then its highly unlikely to mg

Mg the veins stay dark green but with a N def the leaf goes completely yellow

Owd

:-( :-( please i really need to know what to do to sort this problem out its been going on for ages :-(

give em a small dose of grow feed

Increase you feed as ord has pointed out that it is 'N' deficiency no Mg problem.

If you have an EC meter make you mix up to 2.0 & PH to 5.8 - 6.2. . . . Depending on the stage (veg or flower) I thend to make it low during veg (5.8) and high end during Flowering (6.2).

GOODLUUCK WITH THE PROBLEM.


NK.

iv'e also noticed that on my big plants the leafs have white spots on them any idears what this could be??

sounds like the dreaded spider mite

dam i hope not i will go and check and take a pic :-(

no need to take a pic i just checked the underside of the leafs and yes i have spider mites can any1 please let me know how i can solve this problem also its only affecting my 3 big plants hasnt spread to my smaller ones yet.

i need to get this diogosed so i know what to buy on the top side of the leafs there is lots of white specks on most of the leafs and on the undersiode there is tiny moveing black things but no webbing and i looked through a magnifine glass and it does look like tiny spiders if this is spider mites howcome theres no webbing just tiny white specks??

well after reading a little about them on the net im quite sure i have 2 spoted mites :-( does any1 know the best wat to deal with them??

i agree nitrogen defficiency

but what about the 2 spoted mites what can i do to get rid of them??
