3 Week VEG plants won’t grow in height at all

[MysteryPerson6969]

Hello everyone I currently need help with my vegs plants. I’ve been growing for alittle over 3 years but I’ve never came across a situation like this. My veg plants are not growing vertically no matter what I do. I set the light percentage from 50 to 80 percent, I flushed many times, I upped the ppm but anything I do its not growing vertically but getting bushier. This is currently week 3 in veg and are a-little over 8 inches in height.

Room conditions:
-3 fans on low
-Co2 at 800
-LED Lights are 2 feet away from the plants and are at 80 percent
-82 degree
-70% humidity

Strain : lemon cherry gelato

and I’m sure that I did not accidentally give a grow stopper like phosphoload which was what I was thinking.
Please help!!!!

If the light is set to 80% there is no reason for them to keep growing vertically. I would turn it down if anything. JMO


Those leaves looked stressed , especially the tops. You’re gonna cook ‘em

Agreed 100%, intensity is way too high. I don’t put my lights at 80% until week 5 of flower

Thank you very much for the advice I just turned down the lights to the Lowest level

I set my LED to 50% until week 2 flower then gradually increase by 10% every week. Usually don't put to 100% though, 90 at most. Also what's your feeding?

I feed aqua flakes A and B( house and garden), cal mag(advanced nutrients) , nitrogen boost(house and garden), Algen extract (house and garden), amino treatment(house and garden), heavy 16 roots , and fasilator (aptus)

way to hot personally..low to mid 70s at these early growth stages..82 is bordering stress!!!

Info to help you with your lighting.

There is an app, photone for Android users it's free to use as it's still in beta, but for iphone users it's a paid app.

This app uses your selfie camera to measure the ppfd (light intensity) it has eliminated any light issues for me personally and it's free.

Great tool to have in you arsenal.

Hope it helps.

He is using LEDs tho, i would be in the 78f-80f range for vegging, they love it.
I agree it's too much light, but depends if he wanna bushier or taller plants tho he can steer it how he want it, cultivar will dictate a lot too.

always calibrate it to your light ppfd chart to be more accurate ;-)

I want my plants to be taller what can I make that happen since it’s already bushy

Light intensity: Cannabis plants tend to stretch when they receive lower light levels. If the plants are exposed to high-intensity light throughout their growth, they may not stretch as much. Consider adjusting the distance between the light source and the plants or using lower-intensity lighting during the flowering stage.

Light spectrum: Certain light spectrums, such as those with a higher ratio of blue light, can promote stretch in cannabis plants. Using a light spectrum with a higher ratio of red light during the flowering stage may help control stretching.

Environmental conditions: Factors like temperature, humidity, and airflow can influence plant growth. If the environmental conditions are not optimal for stretching, the plants may exhibit limited vertical growth.

this!!!
raise lights to ~3 feet, lower lights intensity to ~60%
how strong are those LEDs you using? 480w+?
cheers

I’m not sure about how strong it is, it’s the regulate gavita LEDs

they have some different types but all comercial leds.. they should be pretty strong for sure.. 3feet at 60% they will deliver for veg.

If it's that little square LEDs from them that's marketed as the direct replacement for DE hps it could be 4feet+ tho that one has a different footprint and if I'm not mistaken it has optics to concentrate light and spread equal to a 1000w gavita DE.

If it's the bar style LEDs from them 3feet should be ok.
