1st Lemme Say Hi -Then Lets Diagnose: Mid & Lower Leaves Sick (Blotches, Brown Edges)

Oh dear, my bad. I begz forgiveness. XD
Cheers for correcting me on that, sis. It's absolutely great to have you here helping on my little growing adventure.
Totally appreciating, from my end. ^_^
 
Thanks for asking Nebula. Really appreciate it. <3
Actually the problems seem to not be getting any worse, which is a very relieving sign. I was meaning to pluck off all the sick leaves, so that i'd be able to notice if any new leaves develop problems. Should I do that? I feel it'll help stay on top of any newer developments, but don't know if I should be saving as many leaves as possible since i'm firmly into flowering now.
But if i'm lucky and things are as good as they seem, then the extra waterings as well as the calcium and epsom salts seem to be helping out.

I've actually been meaning to post up pictures of the grow room since like 10 days ago, but the forum was being funny with me and not allowing me to post anything.
 
Right, so here we have the room as well as the individual gals.

I think you could go either way with the leaves. You do have lots of nice beautiful green leaves so I wouldn't worry too much about plucking leaves that are discolored :)
 
@alltatup

They are, aren't they.
Thanks for the encouragement my friend. Absolutely in love with these girls. I'm a proud father. =)


@Sonnyhad

Well I had added some aluminum foil to part of the wall, but after adding a swinging fan to the room, the foil was creating too much noise, so I took the foil down.
Painted cardboard is a pretty good idea though. I like it. Thanks for the advice. =]
 
What a clever setup! Sonnyhad has a great point about the reflectivity; flat white paint is a one of the best reflective materials! There are some other ideas about reflective walls here if you wanted to check them out, too! :)

You mentioned you're using a 400W HPS flood light in the back, I'm just curious, have you noticed that the buds on that side are fattening more? Or are the biggest buds at the top? I'm always interested in how side lighting affects bud growth because some growers debate about whether top lighting or side lighting is better. Your plants look lush and beautiful, and you've got lots of nice looking bud sites!
 
Oh wow, thanks. It's lovely to hear that from you. ^_^

Funnily enough i've been trying to pay attention to that very point you are asking about. I was assuming to see monster bud progress, but in actuality the buds growing there are not too different from the rest of the girls. It may be because i'm looking at the buds with the HPS light in my face, so it reduces my seeing ability, but there definitely is no exceptional progress I can report.
The plant next to the HPS is Daphne, and she is so tall that her top has actually reached the roof of my grow room, so she isn't getting any direct light, because the she's taller than the grow lights can go and her top is higher than the horizontal reach of the HPS. So I can't give you a fair comparison between top and sides.

By the way, I tried to find a fix 4 days ago to the height problem, and did something. Problem is, I don't know if I might have harmed her.
I put three stakes around the edges of the pot and tried to have her wrap around them, so as to bring down her height. It kind of worked, and I managed to get her top down to light levels, but then the top 1/4 of her main stalk bent over under the pressure. The main stalk has a crisp 90 degree angle like this now:

I'm worried about if this is dangerous or harmful to her. So far the top hasn't died, and the buds seem to be fine, but I can't help but be paranoid.
Of course the next day I tried splinting her up, but she decided to bend 90 degrees at both ends of the splint instead. =/
Hope I haven't hurt her. What do you think?

----

I've noticed the most bud progress and fattening up is with Esmerelda, the youngest plant. Not sure why. Maybe it's because I did zero plant training to her, as an experiment. Or maybe it's because I put her to the side of the room, so she get's a whole 150 watt T5 to herself.
I'll keep an eye out to see if there is any comparable progress between sides and tops next to the HPS. I'll let you know if anything stands out. ;)
 
I actually had another question that was playing on my mind.
It's to do with height and stretching.

From reading your articles I understood that there would be a major flowering stretch for the initial period after switching to 12/12.
Now, we were to expect growth to x2 or x3 times the height of the plant at the moment of switching.
And I also understood, correct me if i'm wrong, that the stretch only lasts for a specific period. The first week or two after switching to flower, and then the plant height stabilizes because the plant starts focusing on bud production as opposed to vegetative growth and height.
Am I on the right path?

Now here is where I am slightly perplexed.
I was a bit late in flipping the switch, i'll admit that, but not too late.

In fact I flipped to 12/12 on 3/2/17. The heights of my girls were as follows:
[TABLE="border: 3, cellpadding: 1"]
[TR]
[TD]Alicia[/TD]
[TD]18"[/TD]
[TD]1.5 feet[/TD]
[/TR]
[TR]
[TD]Brittania[/TD]
[TD]26"[/TD]
[TD]2.2 feet[/TD]
[/TR]
[TR]
[TD]Daphne[/TD]
[TD]24"[/TD]
[TD]2 feet[/TD]
[/TR]
[TR]
[TD]Esmerelda[/TD]
[TD]16"[/TD]
[TD]1.3 feet[/TD]
[/TR]
[/TABLE]


Now it's been 47 days since (~7 weeks), and my girls are STILL growing. O_O
This is from 4 days ago
[TABLE="border: 3, cellpadding: 1"]
[TR]
[TD]Alicia[/TD]
[TD]64"[/TD]
[TD]5.3 feet[/TD]
[/TR]
[TR]
[TD]Brittania[/TD]
[TD]56"[/TD]
[TD]4.7 feet[/TD]
[/TR]
[TR]
[TD]Daphne[/TD]
[TD]81"[/TD]
[TD]6.7 feet[/TD]
[/TR]
[TR]
[TD]Esmerelda[/TD]
[TD]58"[/TD]
[TD]4.8 feet[/TD]
[/TR]
[/TABLE]


Now that's a LOT of growth. And they still seem to keep climbing higher every week. When will they stop the height expansion?
What are the mechanics of what's going on?

As I explained with my post above, the height is creating some issues with Daphne. The other girls are still under control, but I worry that things might get REALLY out of control.


(PS. I decided to count my weeks of flowering based on the time my girls showed clear signs of sex, not based on the time I flipped to 12/12)
(This would put me coming up to the end of week 4 flower, since I first noticed pistils on 24/2/17)
(Seems I still got me a bit of a journey ahead. The finish line seems to be coming up in the distance though. :) :P )
 
Oh yeah, and lastly, before I forget..

Since you recommended maybe transplanting to bigger pots a couple of weeks ago, it's been nagging me. I feel like I want to, but think that I shouldn't. After all, we're flowering, and I don't wanna harm the girls or shock them.
Well lo and behold, a few days ago I water the gals, and while picking up Daphne to move her I see a few roots poking out the bottom of her drainage holes. Now this can't be a good sign I say to myself, and so yesterday I bit the bullet and did what you said I should do. I transplanted her from a 12 litre pot (~3 gallons) to a whopping 25 litre pot (~6 gallons).
Man, it looks so luxurious in comparison! So roomy. =D

I'm thinking of transplanting Esmerelda too. She's been in a 5 litre pot (~1.25 gallon) since the flip. Gonna do that the day after tomorrow. Should I put her in a 15 litre or 25 litre (4 gallons or 6 gallons)?
I'm also considering transplanting Alicia or Brittania too. They're both in 12 litres (3 gallons). What would you recommend?


These are Daphnes roots from the transplant btw:

Green, wear some protective sun glasses when you are in the light of the grow room. I always clip on my shades!!
 
Good job, Green!! Great decision considering that she was rootbound when you did that. That means the absolute least disturbance/trauma to roots. Then you gave her room to stretch. If you think it's the same way for the others, go for it.
 
Bending is a great way to control the height! If you keep the two broken parts of the stem tightly together with a splint (which it looks like you did) it should heal up even at a 90 degree angle. If a stem is really stiff it helps to first grab the stem tightly, and wiggle it back and forth where you want to bend for 10-20 seconds before trying to actually bend it. It kind of mushes up the inside of the new "joint" while keeping the skin intact, so it's easier to bend without breaking anything.

Plants tend to get really tall and stretchy in relatively low light levels, so they may be getting so tall because they want more light. The height is also highly dependent on strain, as I'm sure you've seen from your height table!

Glad to see the transplant went so well! Can't wait to see more :)
 
alltatup Sure, will make sure to wack on my sunglasses when i'm working directly in the room. Would you say HPS glasses protect the eyes, or simply correct colour perception. Was considering buying them at one point.
Yeah, I think I definitely will transplant the rest of the girls. It just looks so spacey giving them a 25 litre pot, almost 6.5 gallons of freedom for the roots. Not to mention i'm sure they'll love sitting in all that new FoxsFarm Ocean Forest, full of all those goodies. ^_^


NebulaHaze Thanks a tonne Nebula. That's such a relief to hear. I would have felt really bad if I ended up hurting the poor girl. Glad that cannabis is so resilient. It's a real hardcore survivor.

Fair enough about the height. What you say makes a lot of sense. Hopefully i'll be able to provide more sufficient lighting with my next grow. But still, this 1st time grow was a heap of fun, despite having things go slightly out of control. These gals are strong and tall, so that's a good sign if anything. =)
 
I actually had a question relating to timeline, at this point.
What week of flowering would you say these nugs look like they're at?
And how many weeks away from harvest do you get the feel i'm at, just by looking.
Cheeeeers <3
