I'd like to know if the leaf stems turning red and leaves turning slightly yellow of this white russian lady maybe normal or not

could it be a reaction of lamp closeliness? (30cm straight under the lamp until yesterday, now I've just moved her on a side, 40cm /15 inches)

It looks a bit like suntan....the stems are turning red only were exposed to light....less evidence in the shaded stems.....
or could also be result of the effort she's putting on flowering....???
her 2 sisters have really dark green leaves

Thanks 4 helping

looks fine too me, should be a very good harvest!

In some strains you see it when uderfed

 

[stinkyattic]

Your pots should be slightly larger- that could be an indication of soil chemistry starting to fail as the plants become root bound.
Do a runoff pH test too and post the results, and also post the pH of the water you used for the runoff test BEFORE you put it through the pot.

also, with moving to larger pots ask yourself... will I fuck up the plant too much bye acting and should I just chill?

i really hate transplanting

edit: (absolutely beautiful lady btw)

you one of those ppl who sais they have not studied for a test, then gets an A?

IMHO, your plants rock!

i believe that is your plants wanting more p+k. i wouldnt transplant this late in the game. just continue as normal and up the dosage a little on your bloom ferts next scheduled feeding. they wont just die overnight or anything you may be worried about.

im with you stih.......time frame says it all and an ideal time to hit with a booster like canna pk13/14, if the purp stem traits genetic id say it would have shown it a long time before 9 weeks of growth! simular effects can be seen with falling temps in late flower but as the leaf looks a litle pale, id say stihgnobevoli is correct.

That is purely genetic, you can tell when it is not..... like if you got a nutrient related issue going on. It shows a deep purple that is much darker and happens on all over the plant including the main stalk.

Thanks to all..... I guess all of you are right

stinkyattic,
the ph of my tap water was 8/8.5, corrected to 6.5, first water that came out was 6.....last was 6.5... I guess it should be done with plain water but it was also time to feed so I've done altogether....checked also that nutes didn't altered the ph any further....

I like transplanting but wouldn't do that at this stage, gal's too big, too high risk of damaging.... yes she may be totally rootbound now...so it makes me sense to add an extra bit of nutes like stihgnobevoli and cMoon said...

yeah, I've been told also by my groshop mate that could be a genetic sign ... he also suggested to cancel the 3d from infirmary cause the gal was doing fine....lol... I was already aware of it ...only would like to understand things and what was really going on......

her 2 sisters show very dark green leaves with a slight beginning of red...but she's the biggest and more charged of flowers weight....and effort....and she's beginning to orange some hairs

many thank 4 joining and counseling.....
