Why are my Graptoveria Oplina's leaves turning yellow?

I just purchased and repotted these Graptoveria Opalinas a few days ago. The ends are supposed to be purple, but a few have a yellow tint at the end. Is this because I over watered them, because they are getting too little/too much light, or another reason? This is a very beautiful plant, and I would love to keep it alive.
(my room has south facing windows)
In this picture, you can see one of the yellow leaves. There is another. There are three plants and a little baby sprout - could they be overcrowded? Thank you!

Comments (11)matt I don't know, but leaves usually shrivel and dry up if too dry. I don't use moisture meter (they are not that reliable, unless you have a better quality one); if I have any doubts I just stick a bamboo skewer deep into pot to check for moisture. Just checked my plant, there is 1 leaf that is yellowing - I am quite sure it is just old and is going to dry up and fall off. There are 3 big branches/stems on my plant, mostly 'naked', with leaves just at the top. It is constantly in bloom - I got it in 2012 and it never stopped blooming yet. It really needs to be repotted (still in pot & soil I got it in!), and also pruned, since there is no branching at all, and is getting too tall. Here is photo of 1 yellow leaf, and top of one of the branches:...See Morewhy are leaves on my hibiscus plants turning yellow
Comments (3)might have a lot to do with planting in july in FL ... how were they planted.. and how have you been watering them .. one thing for sure.. they are stressed ... and it must be severe stress .. if leaves turned yellow in 10 days ... take a hand trowel.. and find out if there is any moisture down 3 to 6 inches.. where the roots are ... both on the gob planted.. and in close surrounding soil ....if you are relying on lawn irrigation.. that is probably the problem ... in my MI... i dont plant ANYTHING in july or august... maybe pensicola is different ... how about a pic or two.. so we can see size.. color.. etc ... ken...See MoreWhy are the edges of my lemon tree leaves turning yellow?
Comments (13)Every year we get fantastical explanations for chlorosis in the fall. All anyone has to do is stick their head out the window and look for fall colors. If you see Maple trees turning red and yellow your citrus will have chlorosis soon enough, unless you supplement them with artificial light. At least a dozen maybe more reasons this is clearly not a salt build-up. Toronto Canada gets only 150 hours of sunlight in October. A small fraction of that if you are growing in the window. Yes Jeff you need a grow light and a grow tent if possible. It is that time of year. Sonnet 73: That time of year thou mayst in me behold BY WILLIAM SHAKESPEARE That time of year thou mayst in me behold When yellow leaves, or none, or few, do hang Upon those boughs which shake against the cold, Bare ruin'd choirs, where late the sweet birds sang. In me thou see'st the twilight of such day As after sunset fadeth in the west, Which by and by black night doth take away, Death's second self, that seals up all in rest. In me thou see'st the glowing of such fire That on the ashes of his youth doth lie, As the death-bed whereon it must expire, Consum'd with that which it was nourish'd by. This thou perceiv'st, which makes thy love more strong, To love that well which thou must leave ere long....See MoreWhy are my arrowhead leaves turning yellow and shriveling?
Comments (8)The first suspect would be the contrast in light levels between where it was sited outdoors and what new light levels are indoors. A plant's ability to adjust to changes in light levels is not unlimited. Something I wrote about a plant's ability to adjust to changes in photo loads: Light Acclimatization The degree to which a leaf can 'acclimate' to changes in photo load is limited. IOW, you can't expect a leaf that emerged under a full sun light load to acclimate to light levels in a dim corner, any more than you can expect a leaf that emerged in a dim corner to acclimate to a full sun site; this, no matter how long you allow for gradual acclimation. Too, the plant's ability to adapt to higher light loads is greater than its ability to adapt to lesser light loads. Using a 1-10 numerical example to illustrate (numerical value of 1 is low light, 10 is high light): If a leaf emerges where the light level is measured at 5 units, it's range of adjustment might only be to 3.5 on the low side, but 8 to 8.5 on the high side. When the level of adjustment required is greater than what the plant is genetically programmed to deal with, the leaf is shed, and this can occur with conspicuous or relatively inconspicuous damage to the leaf. While shed leaves can never be replaced, per se, new branches can form (with new leaves along the new branches) in the axils of dying leaves or from latent buds immediately above scars left by shed leaves. Too, whenever a new leaf appears it will be perfectly acclimated to whatever the photo load is where the plant is positioned (within the limits of what it is genetically programmed to tolerate). The regulating mechanism that determines whether leaves are able to adapt or destined to be shed centers on the flow of a growth regulator, auxin, across what is called the abscission done, located at the base of the leaf petiole (stem) where the leaf is attached to a branch. Steep declines in the rate of auxin flow causes an abscission layer to form, which effectively forms a wall between the dead/ dying leaf and viable plant parts, soon after which the leaf separates from the rest of the plant.
