Please help plant has a problem

Porky101 · Oct 21, 2020

Hi everyone! I am feeding my plant an ec of 1.2-1.5. Under led light @ 800 umols.

18/6.
Ph 6.0

80-85f
35-70 percent humidity.

Should I feed more?

Thanks for any help
Growing in perlite.

You can see the tip of the leaf is showing calmag issues. Also the leaves seem a light green.

How often do you water/feed?

I'm not dimming it. But the plant is getting a lot of light. If I move it away from the light it does better. However I am wanting to give it more light so that it can grow faster. Some although less light solves the issue I don't believe that is the right way to solve it?

Once a day. If the pot ever feels like I'll give it more water. I want the medium to remain wet. Perlite always has air pockets in it.

Do you ever use plain water?

Shouldn't it be more like ebb flow?Say 4 watering a day?

My opinion would be drippers with reflective mylar over pot covering perlite to prevent algae

Think I'd rather move the light up a touch,

The plant will grow faster if its not being stressed by the Light. Turn the power down on it or move it up. I am having to do this with my fc3000 in a 3x3 which is what the lights rated for. A plant can only take in so much light unless other variables are dialed in for it as well. (Co2,humidity,temp,vpd, airflow.) The best way to keep your plant growing quickly is to do DWC hydro and not stress the plant.

Yeh move ya light an put on drippers could be a plan

I really want to give her more light. With the amount of light she is getting she is a bit stretchy. She seems happy at 500 umols. When I put her at 900 umols she gets droopy and calmag Def. If I feed her more I get burn. Maybe it's my low humidity.

If she doesn't want more light then don't give her more light...

OK but then how do I stop the stretch? I have grown her short and stocky before... She even could take the light in the past.. I believe it is a feeding issue less than a lighting issue. Less light solves it because your not pushing the plant that hard. But I want to push it hard and I am trying to figure out hiw to get around this calmag issue. I think humidity will help

Alrighty

So it seems it's not the light?

I put the problem plant back with the rest of the plants and her deficiencies are spreading on the leaf and more leaves are showing what looks to me to be a calcium deficiency.

Any ideas? The plants next to it don't seem to be showing the same problem.

Also it seems it only happens under my leds. Under my T5s this doesent seem to happen. Even if they are under = umols.

Ph 6.2 EC 1.2 80F 70 percent humidity 18/6

@70% rh you need a LOT of air movement.

Here they are. They very stretchy.
