Well, I'm in my first week of flower and I've started to develop some things of concern. I'm getting almost pure yellow leaves on all three plants, two of them more noticeable than others. Right now it is just a couple, but it seems to be spreading a bit. It seems to be the fan leafs towards the bottom of the plant that are effected, though it is LST so they are getting plenty of light. (see pic #1, large yellow leaf) Additionally, a lot of the very small under growth is starting to get pure yellow, but I AM attributing that to lack of light. In some parts it looks like the veins are green, and in others it looks almost purely yellow. I can't tell if it is a nitrogen problem, or something else entirely.


And here you can see the position of the leaf in conjunction with the rest of the plant:

The second problem that currently seems to only be effecting one of my plants and is of much more concern--its gotten super, super limp, but the soil feels moist a couple inches down. I've attached pictures for that, too. I don't think it is heat stress, as the light is 7-8 inches away and the temp at the canopy is only around 78-80 degrees during the light period. I moved it back a bit last night just in case. As you can see, this plant is very droopy. Additionally, some of the petioles are turning brown or brownish/red as well as being super limp.



So, am I over reacting, or could I have a major problem I need to be looking at? As always, I appreciate the help.

Usually when they go limp like that it's either too dry or roots sitting in water. Doesn't seem like that or heat, maybe flush & go half or less strength. You want the dirt to go through a wet - dry cycle. Dry to the point when the pot feels light, just before wilting(takes practice) to throughly saturated, with good drainage & run off. The yellowing doesn't look like anything to worry about.

I agree. I wouldn't worry about that one yellow leaf. The limpness I would worry about. It almost looks too dry.

Love the avatar pic. 1701...... that would be a tasty breakfast.

I was admiring your avatar as well Well, half of it anyway.

I'm concerned that it is too wet. I think I transplanted into pots that were too large. It seems like I can now go a week without watering and the soil still feels ever so slightly moist 3 inches down. Unfortunately, I don't think I can really fix that other than by not watering. However, I'm second guessing myself on the "too dry". I put my finger in all the way down to my top knuckle and it feels mostly dry, but my finger feels kind of "humid" when I pull it out--does that make sense? I don't want to make it worse by watering. Then again, if it really is too wet, its probably going to die because its not going to dry fast enough. If its going to die anyway, maybe I should just water it on the chance that it IS too dry.

The easy way to tell whether it's too wet or too dry is weight. Do you know what the container feels like dry? That's how you can tell. The other thing that can cause droopiness is root problems like root rot which would definitely be caused by too wet. That's why growing isn't easy!!

I guess my problem is what would be considered dry? For example, the fox farms soil is a bit moist straight out of the bag. Would that be considered "dry"? I'm definitely afraid of root rot on this one.

UPDATE: Thanks everyone. I'm thinking it was thirsty. I went down and had another look. I stuck my entire hand down the side of the put (at least 3/4 of the way down) and grabbed a fistful of the soil. I pulled it up and it slid through my fingers like sand. I wouldn't call that "moist" at all. My finger "humidity" test has failed me (I hope). I watered the plant that was wilted (figuring that, if I was overwatering, it was the plant most likely to die anyway) and then compared the weight to the other pots. After the watering, it was considerably heavier, so I watered the rest, too. I've been so paranoid about over-watering that I've apparently under watered. As another question: Any idea when it should show signs of recovery, assuming it was really thirsty?

I like both of your avatars. Together: Perfection.

Couple hours or less usually, is enough if all it was , was thirst.

Indeed. It's only been an hour or so and the leaves are already supporting their own weight again. It's a huge difference. I'm keeping an eye on the yellowing, but most of it seems to be undergrowth, which is to be expected.

Don't forget, the damaged leaves will not 'heal'.
Glad you're recovering.View attachment 2441880

Leaves something for your imagination, for both sexes.

Great!!!! looks like you made it through... just part of the learning curve. Remember about the weight of the pot & how it feels when it's dry. They can recover from being dry a day or so, but if the roots sit in water it only takes a couple hours to get root rot. It's good to saturate until about 1/4 of how much you put in runs off. 1 gal = 1/4 gal. runoff. Then drain to make sure it doesn't sit in water.

One last update: Wow. Talk about a complete 180. All three plants look like they grew two inches over night (probably because they are standing at attention now). Additionally, the one super limp plant's leaves are now fully upright. The main cola was so droopy that it had fallen over on its side, but now it is vertical and the stem feels so stiff that it would snap if I tried to bend it much. It went from feeling like a bunch of overdone pasta to feeling like an oak branch.
