Elias2107 How often are you giving them that?

[Rwise]

Wood takes in N while decomposing releasing it only after being composted.
But whats up with all the white spots? Have you looked for bugs with a 30x zoom?

[Franklin]

Yeah I'm with rwise, I see some white splotches on there, it doesn't look like powdery mildew to me but it might be. Also, I disagree with the usual practice of stripping yellowing leaves, IF you're doing an organic grow which sounds like the case here. If that's happening from the bottom up, that's usually a sign that the plant is moving nutrients around. Leave the leaves on there until they're dead because it's a bank of nutrients. Perhaps the reason the problem moved to the upper leaves is now the plant is pulling the nutrients out of the upper leaves and into the buds. You might want to consider a worm compost aerated tea to get some nutrients to it more quickly. I don't know though, man, I'm just kind of shooting in the dark

[Elias2107]

I am not growing organically, but I think trimming the lower leafs hasn’t helped a bit. As you said the problem is the same but has moved up now.

[AGH]

So it looks like there may be some relatively minor problems, but before we get to that, two question.

1. (the most important one) How long have you had them on 12/12 lighting? (The answer to this will decide how urgent the problem is, if there are multiple problems which one is most worth pursuing, and what the best plan would be)
2. What is that metal thing the pots are sitting next to in the pic from post #679?

[Elias2107]

The lights have been on 12/12 since 21st of January. They were growing perfect the entire grow until the end came along. Now they have been starting to show some yellowish leaves and are starting to look droopy. I have no idea what the white stuff on the leaf is. The metal thingy I think you mean is a chain used to hold the lamp in place. I also use a mirror and because of this the temperatures can rise a lot too. Last max-min I checked it was around 29 degrees! I lowered the lamp to decrease temperatures. The circulation is good as well with two fans. Any suggestions?

[Bluey]

You're at the end of your grow...it's giving everything to the flowers, that appears to be what's going on. Can you get pics of the trichomes or pistols if you can't? Heat may not have helped but 29⁰C should be ok for most..it's at the high end of ideal

[AGH]

That length of time from 12/12 is all we need to know and is pretty much what I suspected. Like Bluey says, you're at the end of your grow and that's just what cannabis plants do at the end of their cycle. They've been in flowering stage for about 7 weeks, and most plants are harvested between 8-10 weeks so you're nearing the end of this grow - good job making it through!

Just like corn or soybeans (Midwestern boy here!) in the fall, they turn brown and dry up and then it's time to harvest. Your plants are doing exactly what they are supposed to do. You'll also notice that they'll start drinking less so be careful to not overwater.

Start looking at the trichomes under a magnifying glass. You'll see them starting to turn cloudy and then amber. There are different guidelines when it comes to using the trichomes to determine readiness, but in general when I see about 10-20% of the trichomes turning amber, that's when I know to harvest. Of course, the best way is to take all the factors into account:
- Length of time in flowering
- Are the pistils orange/brown/amber and curling in?
- What do the trichomes look like?
- What is the overall activity of the plant?

It looks like your pistils still have a little changing to do, but you're getting close to your harvest window. As the days continue, you'll see those start to all turn orange/brown/amber and they'll shrivel in. Continue to be patient and keep notes on how the plant behaves towards the end of flowering so that on your next grow you can adjust your care of them. It looks like you have some pretty healthy plants and you should be pleased with yourself!

[Bluey]

There is some amber/golds in the first pic...possibly some in the background of other pics. Can you see amber/golds on it? I really suspect your plant is almost or is done...do you know if she's drinking much?
Pics of buds would be great..show us any problems..check for loose buds

[SoOrbudgal]

Is that a leaf you took these pics of ? It's not ready in my book got a long way to go weeks.

[ChubbNugg]

dont smoke the rayon fiber

[Wehee]

Hi! First timer here, and I was wondering, what's up with my plant?

[Bluey]

Without any info apart from the pic Wehee I'd say well and truly overwatered...early veg right?

[SoOrbudgal]

Wehee we need a wee bit more info about your plant. Is it Auto or Photoperiod, age of plant, soil or hydro, type of light and distance from plant. And a full plant pic would be good.

[Wehee]

Hi, this is thw whole plant. I don't know which strain it is..

[Franklin]

I've been told those cabbage looking leaves are from too much nutrients

[Bluey]

Cut the bottom leaves off that are on the dirt. You need to train the plant. It's growing too tall and you have large node spacings which indicates insufficient light....remember light is food for your plant..your leaves look pale in those pics and are flat looking so as abovevon that one. Good luck

Nutrient tank stability issues

Tank is a light proof 30gal or 120ltr tank. Temps pretty stable 70 to 72⁰F or 21 to 22⁰C.
Growing in coco so 2 part quality flower nutes plus a cal/mag additive. I'm week 6 to 7 into flower
Using rainwater. Have only received less than 2" 50mm of rain in the past 3 months but had recent downpours over the past couple of weeks totalling 1 to 2".
I dont run air stones but do have that option. No algae in tank just some minor sediment in the bottom and minor accumulation of salts on the sides above waterline from the evaporative process. Ec of water is zero.
I add my 2 part nutes with vigorous mechanical stirring and then cal mag to bring it to an EC of about 1.6. I have had to pH down lately but not much, from around 6.8 down to 6.2 using citric acid.
I found my pH is climbing up. After 1 day it will go to 6.65. After 4 days up to 7.1. The EC is dropping at the same time. After one day from 1.6 to 1.3.
I am correcting this daily atm but I need a better strategy as I am away from the grow for 4 to 6 days at a time atm and I am at a point in flower where trichomes are beginning to form...a critical period.
Any suggestions please.

[Bluey]

Problem solved. It was something growing in my tank, likely algae. For anyone interested rising pH, dropping EC and more and more pH down, like way to much was required to knock it back down.

[Bluey]

Update. Problem not solved....I think it's the cal/mag supplement but don't know...I'll drop that from the feeding schedule this week as I'll be about day 56 of flower and they'll be close to done.

[Elias2107]

How can I solve?

[SoOrbudgal]

You a bot?? Elias2107 you sound like one

[AGH]

Hello Elias 2107!

Before we can help, we'll need more info:
- What are you growing in?
- How old? (the plant, not you)
- Pics of the whole plant?
- Lighting, nutrients, watering regime, etc.
- How has the environment been? (ie. temp, humidity, airflow, ventilation, etc.)

At first glance, it looks like you have some pH issues as well as some bugs but more info and photos are needed.

[Elias2107]

- Im now growing in a 12,8 x 12,8 x 20 cm and 20L. However I’m going to transplant them in a few short days to a textile 50L pot. Soil mixed with: lavameel, perlite, universal airy soil with little added foods, wormhumus.

- all lady’s came out of the soil on 12th of march have been growing on 18/6 since. I did the training techniques defoliation, lst to most of them, one I topped as well. Not the one shown in the picture. That’s a sugar bomb punch from Dutch passion seed company.

-will show in next post..

- in a 20L vat: 4,7ml/L vega, 2ml/L rhizotonic, 2,5ml/L zym, 2ml/L Boost, 2ml/L alg a mic, 1ml/L sensi cal-mag, (30ml) cold pressed seaweed with EC; 1.5 en pH; 5.9

[Bowhunterwoody]

Also if that's the pot your using I'd say it's definitely time to re-pot.

[Elias2107]

Can I repot if I just did plant training on them

[Bowhunterwoody]

In the pic it looks like a smaller pot. Like a 1qt. Sounds like you already repotted. If they are in soil I'd say pH of 5.9 is pretty low. 6.3-6.5 or a little higher for soil. If they're photos then yes you can repot. Just might make them grumpy for a while.
