Thanks for the additional info!

Good for up-potting them. Looked too small.

It looks like you have some sort of bugs. Check very closely on top of the leaves, on the bottom sides of the leaves, and in the soil. Those white spots look to be from pests munching on your leaves.

It's also likely, as Bowhunterwoddy mentioned, that you have pH issues. Those are likely leading to what appears to be a calcium deficiency.

Before trying to fix any deficiencies, make sure you have everything in the environment taken care of: temp, humidity, watering regime, ventilation, circulation, lighting, and proper nutrients. If the pH is off, different nutrients aren't able to be absorbed by the plant. So prioritize dialing in the environment before adding nutrients as there are likely enough nutrients but they're just not able to be absorbed. Once you have the environment dialed in (or while you're doing that) make sure your pH is good. Once you have those things set, wait a week or so to see if there is any improvement, THEN consider adjusting nutrients or supplements.

I made the ph from 5.7 to 6.3 by adding tap water. The new EC became 1.28 so I added 20ml of sensi cal-mag to my 20L vat so changed it from 1ml/L to 2ml/L since I found EC to be on the low side and agree that the deficiency might be calcium.

Good 1 Elias2107

[Elias2107]

I transported the lady’s to a bigger pot and gave them 60ml (in a 20L vat) sensi calmag and 20ml of canna vega extra because they are both high in N and I personally think it’s a nitrogen problem. What do you guys think? I still have some canna flush so if I need to I can use that too.

[Bluey]

You might also be overwatering them...keep on top of pH and just give them good nutes and you will be fine

[SoOrbudgal]

If it's been 3 days since you repotted them i'd give them a big drink of water and leave it alone. Sounds to me like she has enough of the chemicals.

I apologize for the English, translated by google translator
RDWC is about 650L of solution. All fertilizers and stimulants are from GHE. The ICE lamps are about 320W/square meter, currently suspended 70-100 cm from the plants, working at 40% power. Temperature and humidity are not measured yet, but I think there are no extreme indicators.
In the first landing, I did not correctly calculate the dosage of chlorine and burned the kids.
After changing the solution, the water bloomed and began to smell like a swamp. I found a lot of light leaks in buckets. Replaced the solution, strengthened the light insulation.
11 arel planting of new plants next to the old ones, on which a minimum of hopes were already pinned. On April 11, they landed as hard hats were thrown off.
Before the landing of the new landing, somewhere from 4.04 to 6.04, the solution was replaced and the Ph. PPM of tap water was gradually adjusted 130-140. After correction, about 150 ml of FloraNova MAX Grow was added.
And further:
7.04 under the root stimulator Pro root 2ml / l only 3 liters.
9.04 PS 5.6 PPM 273-283
10.04 PS 5.8 PPM 283 At the root gave 6 liters: 24 ml Revive Advanced; (I thought that old plants with burns will benefit and maybe someone will recover)
1 tablespoon of mycorrhiza that is with a shark.
12.04 PS 5.9 PPM 290 - 2 ml of electrolyte
13.04 PS 5.8 PPM 296 - 2 ml of electrolyte
14.04 PS 5.7 PPM 293
15.04 PS 5.8 PPM 291 - 3 ml of electrolyte
16.04 PS 5.0 PPM 297 - 1L of tap water
19.04 PS 5.7 PPM 297 - under the root for 7 liters: 1.4 ml Pro root (0.2 ml/l)
14 ml Humic GHE (2ml/l)
14 ml Fulvic (2ml/l)
1 tablespoon mycorrhiza with shark
20.04 PS 5.7-5.8 PPM 304
21.04 PS 5.8 PPM 303
22.04 PS 5.8 PPM 304 - 40 ml Flora Nova Grow
40 ml Humic
60 ml Fulvic
For some, it twists the lower leaves slightly.
PH 5.8 PPM 327 - 3 ml of electrolyte
40 ml Flora Nova Grow
40 ml Humic
60 ml Fulvic
5 liters tap water
Under the root for 7 liters: 21 ml Revive (3ml/l)
1.4 ml Pro root (0.2ml/l)
1 tablespoon mycorrhiza
23.04 PS 5.8 PPM 350 - 3 ml of electrolyte
60 ml Flora Nova Grow
4 ml of tap water
24.04 PS 5.3 PPM 390 - 1 l of water
In plants whose lower leaves were twisted, necrotic gray spots appeared on the same leaves.
25.04 PS 5.4 PPM 390 - 15 liters of water
3.4 ml of electrolyte
27.04 PS 5.4 PPM 385 16 days from the helmet. They develop slowly, the root develops in my opinion also not very well. Those who twisted the lower leaves now the leaves dry out at the edges and die. They are very slow in growth. There are several of the most resistant bushes, their leaf edges bend upwards.
According to the PPM, it is clear that plants practically do not eat... The solution has no unpleasant odors.
Almost all plants are pale with green streaks.
What am I doing wrong and how can I fix it? I tried not to give too much anyway, so as not to burn the plants.

Brown marmorated stink bug- according to google






So I found one on a plant that I had just been tending outside of the tent and had put back 5 minutes prior. Didn't see much on the GWE site about them, googled a bit, neem oil and soapy water, and picking them off appears to be the treatment. There was just one and I had just been all over the plants for training and trimming, did not see anything that looked like eggs or other infection. I'm hoping that is was a one off bug maybe from when I was trimming and it wandered onto the plant while it was in the barn for the trim. Anyone else have experience with these? Share please.

[Bluey]

I get them here. Never caused me any grief

[Rwise]

Kill them, they are bad bugs and nothing in nature eats them (the green ones too), they will attack your plants. I have found one with a hole in its back, so maybe something is eating them, smash smash smash.

[AGH]

You're good, just a brown stink bug. If you only saw the one and it was likely while the plant was not in the tent then I wouldn't worry. Keep an eye out for anything, but just your normal monitoring with a yellow stick trap or two will help you make sure that nothing is populating.

[Elias2107]

I have some sort of infection on my plant. It’s especially located at the lower parts of the plant where the leafs have a bunch of white spots on them. On one of my buds the leafs have died too. The rest of the plant looks absolutely great as you can see in the last picture. I only hope I can stop this problem from spreading before it will decrease my potential harvest. The nutrients I give them are ph6.2 and EC 1.8. Low humidity and medium temps

[Elias2107]

What products can I use that are these: “ diatomaceous earth over your grow medium, insecticidal soap, neem oil,”

[AGH]

These are the products that I personally use/have used:
- Diatomaceous Earth: https://www.amazon.com/dp/B072J8Z28F...refix=diatomac
- Insecticidal Soap: https://www.amazon.com/dp/B00192AO90...sprefix=insect
- Neem Oil: https://www.amazon.com/dp/B006QYSAPQ...=&sprefix=neem

[Rwise]

Neem oil should never be used on flowers, many have had issues. IF I must spray flowers I use ISO mixed with water 1 part ISO to 8 parts water. It evaporates leaving nothing behind, it is a contact killer like spinosad so needs redone ever 3 days for at least 3 treatments. ( I have went 50/50 without issues)

[Damian]

Are these bananas

[Bluey]

Really bad pic but my guess is that's a female cannabis plant as opposed to a banana tree.

[AGH]

Ha, Bluey you crack my $#!+ up!

Really though, we would love to help out, Damian but we definitely need closer photos. Nanners are something that every grower constantly keeps an eye out for and they're often small so try to get a good clear closeup of what you're concerned with. You can also check out the GWE site and search for hermaphrodite plants, herms, or nanners and you'll get some great articles as well as pics of what to keep an eye out for.

[ChubbNugg]

Yes, by god, Every last one of them!

Use yellow insect repellent glue

[Shitil]

Is it possible for a female plant to be fertilized by several male plants? And the seeds produced by that female plant are from different species? I planted four seeds from a female plant, some have 9 leaves, some have 7 leaves, and they are completely different in appearance, if they are from a female plant.

[Bluey]

No. Not possible. You must be smoking some really good shit man

[Rwise]

IF these seeds are from an outdoor grow, then yes every seed could be from a different male, not likely though. "species" is the wrong word, it is not uncommon for sisters to display different genetics, even with clones.

[Shitil]

I use fluorescent (white) CFL lamps

does adding fluorescent lamps with blue color have a better effect on the growth of small seedlings and growing seedlings?

[SoOrbudgal]

I don't know does it? What have you read about seedling an light?

[Bluey]

Deep violets low low 400's nm will promote root growth in early veg. some say.

Some say that the same and lower UVA/B/C will boost oils/cannabinoids and terps in late flower but this has failed to be replicated in all controlled lab testing to date so could just be bullshit. A dark period for 3 days prior to harvest probably works better IMHO.

I used 405nm in early to mid veg and have always filled a 13 gal pot with roots during veg. Is it better? No idea. I think with or without it would fill anyway so I've shelved those globes for purpose built grow lights but continue to supplement from flip with 660 & 730nm to close to harvest...they are not very strong and mounted 30 to 36" above canopy so just leave them on a 12/12 with the main lights. Works well I reckon.

[ChubbNugg]

it is my experience that if you light up the seedlings with florescent light in the 6400 kelvin color temp range, the younglings love it over here.

[Shitil]

only one Leaves are getting spots. , two leaves from the bottom are yellow

[Bluey]

You have a calcium deficiency.

Treatment will vary depending if your growing in coco or soil.

First step is to check your pH. pH too low at the roots is the main cause of what you are seeing

[Shitil]

Yes, I use city water. There is tap water for drinking in our country. I pour water in a bottle for a day so that the chlorine settles. I bought calcium fertilizer, do you think I should give it?

[SoOrbudgal]

Also check for bugs and powdery mildew are those outdoors?

[Shitil]

only one Leaves are getting spots. , two leaves from the bottom are yellow

A combination of leaf soil, coco, compost, sheep manure

[Bluey]

So you are giving it tap water? Can you measure the pH waste water runoff that first comes out the bottom of the pots?

[Bluey]

A quick fix given you are using compost is to add some dolomite lime to your water...I don't know the quantity you need though. This will add calcium and also up the pH and do both immediately

Yes. But give a reduced amount....you should fix your pH issues first though
