Dark spots on my leaves, 2nd time gorwing

[joana1998]

hHy guys, I'm currently on week 6/7 in the vegetative state. a few days ago these spots appeared on my plant leaves, I'm using a spiderfarmer sf1000 with the dimmer at 85% and the height of 40/45cm from the top of canopy, temperatures around 25ºC and humidity about 60/65%. any suggestions of what it could be? Sorry for my english

Looks like Potassium [ K] deficiency.
What are you growing in soil?
Have you offered any fertilizer yet?

 

[GoldenDragon]

It looks like the led lights were too strong for the plants and the leaves were burning. But all the new growth seems ok now so maybe the plants have adjusted to the light levels. They are kind of pale in colour so some cal-mag would probably help green them up and will probably help them under the strong led light better. Keep an eye on the leaves near the top of the plants now, any burning signs like before then turn your lights output down abit more.
Edit. All that patching and pale stripe on the leaves between the veins means they need some cal-mag.

The plants are underfed. The deficiencies you’re seeing are just the first to pop up. Don’t go chasing individual deficiencies just give it a solid feeding with balanced nutrients and 2ml/ gal cal mag

Get a yellow sticky gnat trap in there to amuse some of us.

What country are you in if you don't mind me asking?

I just went to the Royal Queen website and this is the closest they have to what I would buy: https://www.royalqueenseeds.com/growing/553-grow-kit.html

What @Oldguy71 and some of the others are saying is that your plants look hungry. They need a good feeding with a fertilizer that can supply the nitrogen, phosphorous and potassium (NPK) your plants are needing. @GoldenDragon went as far as adding Cal-Mag to your routine. The bottom line is they are on point on what your problems are

Edit: These in particular are the items in Royal Queen's nutrient program. I don't know if you need everything in their lineup because I have not used it before.

Easy Boost Organic Nutrition​

Easy Boost Organic Nutrition contains all of the key nutrients your plants need throughout the growing cycle. A single dose is enough to keep your plant thriving for 10–12 weeks. Simply mix the pellets into your soil and you’re good to grow!

Vegetation and Flowering​

After making it through the seedling stage, your plants will become increasingly hungry as they begin to pack on size.

Easy Grow Booster Tablets​

Easy Grow Booster Tablets provide everything plants need as they charge through the vegetative phase. High levels of nitrogen enable plants to pump out large and luscious fan leaves to optimise photosynthesis.

Easy Bloom Booster Tablets​

Cannabis plants experience a change in appetite as they enter the flowering stage. They require less nitrogen and more phosphorus and potassium to produce the stickiest flowers possible. Easy Bloom Booster Tablets provides a perfect formula for the blooming period.

im from portugal, um using https://www.royalqueenseeds.pt/growing/568-micronutrientes-easy-plus.html

 

[steamroller]

You got it right. Use the micros you have along with each of the others.
Yea you can remove the worst leaves. They won't heal anyways.
Now you watch the new growth.

Yes, I looked at what you're using and there is nothing wrong with it that I can see. It's just not complete. Cannabis has nutritional requirements listed as Macronutrients which would be your NPK and then your micronutrients which would be Ca,Mg and others ... If you add the Easy Combo booster pack to your routine you should be fine because then your plants will be receiving a pretty well rounded nutritional routine.

Portugal - I don't know much about it to be honest. Regardless, glad to have you on the farm.

 

[Oldguy71]

Are you dissolving a tablet into water or did you work it into the soil? If dissolving into water use about 20% less water. If worked into the soil, dissolve one tablet into gal/ 4 liters of water.
