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.
 
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.
 
How can I solve?

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.
 
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.
 
- 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
 
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.

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.

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.

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