Really droopy plants in coco

Ok so I have 2 rp kandy kush seeds, grown in coco. Currently using the lucas formula for nutes. Started in solo cups to 1 gal to 3 gal now. Perilite was mixed in with the coco. Been watering at least every other day, sometimes daily before i transplanted.

So the droop really started a little before I transplanted them into the 3 gal containers. I thought maybe I over watered them. So I let it dry out before re watering. They wilted even more when they needed water, and perked up a little after getting watered but were still really droopy.

Was still running half strength nutes, thought maybe they needed more food. Bumped up to full strength and no difference.

Under 450 watt mh light right now. Temps never over 80 when lights on, never under 68 when lights off. Rh usually stays 40-50, if it drops lower than 40 I'll run my humidifier.

I can't figure it out. Starting to think maybe it's pests or disease, maybe root problems? Lemme know what you guys think.

Ps I know they stretched a good bit. I had them pretty for away from the mh for a few days.








I appreciate any advice

The less droopy plant in the pics is doing much better right now. I turned my light down to 50% wondering if that was the cause. The other is still drooped pretty bad, and had reallllly slowed down on growth.

they stay like that all day? if its only at the end of the day, its normal

Those were rootbound i bet.

Maybe a small magnesium def too

Yeah the mg def is showing. Thinking it was due to slightly low ph there. As for roornound I suppose it possible. Went from the solo cup to 1 gal on 3/11 and then to the 3 gal on 3/31. On the droopy one the coco would hardly break up around the roots. Maybe that is indeed the problem with it?

I wish they were just sleeping. It's limp all day.

The one on the right seems to be back on track minus the mg def. Hopefully the other will come around soon, maybe take it out and clear the coco from around roots a bit better?

dont touch the roots. how often are you watering? how high is your MH? probly dont need that cfl if you have that

I'll take a stab at a diagnosis.
Too much heat and light for that small of an area. Although you say 80 degrees for your room temp, I would guess that the leaf temp is more in the 90's under the HID. I like to keep my room temps at 70 degrees and leaf temps under 80 degrees.

Was every day before I transplanted now every other day as after 1 it's still pretty damp. 2 it's slightly damp but not dry. Light is 10" now that it's down to 300 watts. Was 12" at 450 watts. The cfl is just there from the last run. I had 4 under my scrog.

That was my thought too especially with the new growth being curled up. But my thermostats are attached to my hood like 2-3" from the bulb, that's where that 80 degree reading was comig from. I think it was to intense lighting to early. Shoulda left it on 300 watts a bit longer.

Definitely a Mag problem though. See how the vein areas are dark but in between is light. Those are called stripes. Classic Mag.

I think you're right about the light though.

looks like the audience choice is too much light. you're definitely not overwatering, so its not that. i would raise the light to 18"+ if you can, you can always lower it. you want those fan leaves to reach up like groerr's posts, check them out.

The mag deficiency is in relation to the high transpiration rate, the plant is using K in an attempt to cool itself and is not taking up the mag. Otherwise the K+ ion is being preferred for uptake over the Mg++ ion.

I can see that for sure. Good info, i was gonna add mg but it shouldnt be necessary correct? as its there just not being used. After turning the light down they are really turning around. I'll get a new pic after work.

Running the lucas formula I've heard, can be problematic with Mg deficiencies. Never ran it so I would be no help there.

Nar look at the pots and the small plants lol they aren't rootbound

2017 mate!
