6wk flower, leaves and stems turning red fast, should i be worried? '+PICS

I must admit Im totally lost now, after switch to 12/12 fan leaves went yellow pretty fast and most of them died off, those that didnt were ok until about a week ago when they started going red-brownish :/ I ignored it for a bit and now noticed that this rediness is creeping onto bud leaves too and the stems are turning red as well. Is it normal? I mean, theres loads of posts from folks worried about leaf yellowing but i havent seen anything like this before.
Another thing is - they have clear, milky and amber(!) trichomes! Lets say 60/30/10 % respectively. WTF? I thought that they get ripe pretty evenly. What do you guys think?

what im lookin at looks GOOD! what is it?....yellowing of lower leaves is normal in late flower

and trichs are different all over the plant,you just come up with an average

Looks good man what strain is that? Oh and a lil N in flower is a good thing to be sure.

Thanks guys, sure the buds look kinda nice and believe me it smells fuckin awesome Its feminized White Diesel from White Label/Sensi Seeds. So you reckon the red leaves are nothing to worry about? Its my first grow so all I really want is some decent smoke for xmas ;]]

Heres a pic of both plants to let you see the scale of the problem(if its a problem ofkoz)

they are normal

Sweet, thx

they just finishing up,,,.,,, your flushing them, right????

when you feed em are they getting nitrogen since theyre flowerin? some of foods dont have Nitrogen in flower part and add to yellowing, alot of ppl have near dead plants at the end of flower due to lack of nitrogen might be worth checking

After months of lush green growth, they die an ugly wonderful death, this is the cycle of life.

Be proud and enjoy.

Well i didnt really flush them, i just give them plain water now. Until a week ago I was giving them Biobizz bloom 2-6-3.5 in rather mild doses but with every watering

Nice one ;]

What were your temperatures. If you have a min/max thermometer, you can record the temperature swings. cool temperatures can bring out colors like that sometimes, especially in genetics that are prone to color.

The red is genetics to be sure, but im fairly positive you need some N man. And need to trim those crispy leaves as well. I understand some of your leaves are gonna yellow but question is how many of those leaves you gonna have like 1,2,3 weeks from now? How your buds gonna grow is siz with no leaves?

Well the temps are pretty stable at around 26C lights on and 20C lights off, but there were few occasions when i left the heating off and temps fell as low as 15C. The thing with the leaves is that right after i switched to 12/12 the fan leaves started yellowing immediately and most of them died off pretty quickly. I tried to add a tiny bit of the veg fert to help it but that didnt bring any effects. Having said that, Im pretty certain i have a pH problem but failed miserably at trying to measure it properly.

Adding Cal/Mag during flower will help with n uptake. check out riddleme's thread on how he continued veg nutes throughout, but if you have a def it inhibits the uptake of N and your buds feed off the fan leafs that can't replenish and they die off.

Also, Bio-Bizz is pretty mild for plants.
Getting enough organic Nitrogen is tricky, and you can definitely up the dosage, or find a supplemental.
Cal-Mag is not Organic, so if that matters you can look into other nutrient lines. Look into the Organicare line from Botanicare, they have some great supplements, as well as a slow release granular. FoxFarm also has some good slow release granulars to add along side your liquids.

Thx guys, I will definitely look into this although I might have to search for alternatives as botanicare products arent really available in the UK. Any good but not ridiculously priced pH meters that you might suggest? I have this thing but Im not convinced it really works and might be the actual cause of my problem(I assumed it works lol). So i thought I might as well get a proper one since I definitely want to grow some more

hey guys - is it just me, or are his pots too small. The rule is 1 gallon per 1 foot of height.... right? Aside from the potential PH problem... what do the roots like? Just a question as you don't want to leave anything out that could possibly ruin a crop.
