Yellow leaves all of a sudden!

[TopThumb]

I've got 3 Shishkaberry clones growing outside since the beginning of May and just in the last week the leaves are turning a bright yellow. Is this normal or maybe I'm over watering since it's been very hot here since May(90's to 100's). They are growing great and are almost 6' tall and looks to be flowering now. Any insight would be appreciated. Oh, almost forgot, I also have a MAC 4 doing the same thing.

Been pulling yellows from the bottoms of both of mine for a week or two now. Got a picture? Much easier that way. Probably just the normal progression of the plants. They take nutrients from unnecessary leaves down below as they attempt to reproduce later in their life cycle. Could be a hundred different things though I suppose. Pics would be great !

I was going to take a pic but it was getting dark but I'll get a couple tomorrow. Most of them are on the bottom with a few going toward the middle.

Hey TopThumb, if they have been growing since May its expected that the plant starts develop yellow leafs, her lifecycle are almost over now and i think that harvesttime is coming really soon. Pics would be good to really get an understanding. Take care and happy growing!

Here are some pics of all 4 plants. I was thinking that maybe I should up the dose of Tiger Bloom a little if it is needing that.

Look like they need food NPK

[billyboy]

agreed - they look hungry

[TopThumb]

What gives it away that it needs food may I ask?

[TopThumb]

Fed them today. Main reason they are drooping a little is because I stopped watering for two days thinking they may be getting over watered.

Look for tiny bugs in the soil.

[TopThumb]

Found some tiny ants on one of them and took care of it. Nothing anywhere else on the plant or soil.

[TopThumb]

I've fed them NPK and the yellowing seems to have stopped or slowed way down now. So should I pick off the yellow leaves?

[SoOrbudgal]

Yes if they don't come off real easy clip them with scissors don't shred the truck pulling them off

[TopThumb]

Most of them fall off by touching them.

Post a new pic

[TopThumb]

Will do tomorrow, too dark now.

OK, here is a couple pics of the plants as of today. I think I still need to feed them more but they are doing better.

Wow they look much better
