Sudden droop helpppppp

Sumby · May 17, 2018

hi guys plants have been doing well. They’re under 500w led in soil. Using Biobizz grow. The last few days they seemed lifeless. Iv been very careful not to overwater. Gradually increasing it over the weeks but always checking for dry soil and lifting the pots. As they started to get droopy I held off on the watering Incase they were holding water below but gave it a few days. Soil was dry so I suspected under watering. I gave them a good watering, got run off too. However the next morning they are even worse. My intake flow seems to have slowed recently so could it be co2 deficiency? Incase I have left the grow door slightly ajar for more intake. Help

Looks like over watering to me , leaves are fat with water. How much do you water? In litres.

Sumby · May 18, 2018

Not lots. Usually around 0.5 litres each as I was building it up to make sure I didn’t overwater

Sumby · May 18, 2018

Any advice guys ?

Nitrogen toxicity mimics overwatering.
Biobizz soil ... what nutes are you using and are you going half strength?

Sumby · May 18, 2018

Using lite mix soil. I’m just using Biobizz grow 1ml/l usually but as they have got bigger I used 2ml/l. Sometime put 1ml of bloom in there too

My lights don’t come on for another 2 hours but as soon as they do I will give an update

They are dark green in the pics, plus the droop, makes me think N toxicity.
Overwatered plants tend to yellow.

Never experienced C02 deficiency. Got to be extremely rare.

In my experience your leaves should really never be that dark green, this is a common sign of over fertilization.

My advice is to leave her for a few days; no water or nutes.

After letting her dry out good( half inch- 3/4) run a good flush; then assess where you're at from there.

overwatering possibly related to insufficient light? What is the true watts of your LED? Based on most LED manufactures BS, its maybe 250, which isn't enough to keep the plant happy AND growing. More light usually allows you to feed and water more

They are 100w led corn lights. They are extremely bright and there’s five of them. I believe they are around 5000k on the scale. They’re about 5 inch’s from the tops too. I was sure I’d not overwatered as the pots dry after around 2/3 days I lift and check and as iv said I only increased water gradually so as not to over water. I was more concerned about underwatering as filling my watering can with four litres and sharing between the 6 doesn’t seem like too much. Hmmm Think it could be overfertilizing then. I have been adding ferts pretty much every water

Also these lights were from a warehouse that I worked on , the led corn lights replaced 250watt hps bulbs so I don’t believe their wattage to be too far off 100w

Since you're so far in veg, I doubt it's a light issue. Those issues would have showed up before this point.

If you did feed every water it's almost certain that you're over feeding.

You need to flush in this case; and since you don't have any burn, I would recommend waiting a day or two until the top of your soil is dry. Look into wet and dry cycles of plants for more info on optimal watering.

Here is how they’re doing

Sumby · May 18, 2018

These are the new sprouts.

drsaltzman · May 18, 2018

Yeah, based on your comments and their look those are definitely not overwatered.
I like Final 2X's advice. Dry em out. Flush em good. Reassess.
And maybe raise the lights a couple inches.
They'll rebound.

drsaltzman · May 18, 2018

You got a couple fan leaves praying. That's good.

Sumby · May 18, 2018

Thanks very much for your info guys. Very helpful. I will dry out and flush and see how it goes. I’ll post pics of any improvement

Since when does N toxicity mimic “overwatering”? Flush? Holy shit, such awful advice!
