Cupping leaves

[Fantomlimb]

Hello all. So my grow has been through some stuff. I started it in an aerogarden and when I realized it was going to get too big to stay under the light, I opted for a grow tent set up. So I went from the aerogarden light to a new Vivosun 300W LED and two Sansi full spectrum 36 watt leds. I already had the Sansi as supplementary for the aerogarden and didn’t want to waste them. Plant seems to be doing great but for some cupping of the leaves.

I just defoliated it about three days ago. PH is a daily battle to keep it under 7.0. But it hovers around 5.6 to 6.5 most of the time. I’m in my second week of flowering. 4 days left. PPM went from 900 to 396 in 3 days. I top with distilled water. Water rez is 78 during day and around 69-72 lights off. Air temp is 74 max lights on and 66 lights off. Humidity is kept around 45% - 49%.
Any help is appreciated.

Hello and welcome, I’m not about a deficiency but those res temps r pretty high, I am pretty sure when the temps get close to 80 the water doesn’t hold oxygen very well, and also it can cause issues with root rot and slim build up which can cause ur plant to do weird stuff, have u checked ur roots lately?

Roots look great, they aren’t even stained from the nutes. Very white and thick. I’m using Hydroguard every week to help keep the bad stuff away and I’m also using an air stone in the Rez as well as the built in pump. The built in pump is what heats the water unfortunately but it’s needed to drip nutes into the grow sponge. I have it run 10 min on and 60 min off

Less cupping today, but leaves are pointing down.

Here are the roots

Give them a few more days to see if they begin reaching before you stress to much.Those roots look healthy and the leaves look lush.Since you said your in week two of flower i do suggest more p-k due to the droop and red petioles i see.Some times when i flip plants they have intense cellular growth right after the flip and look like yours for a few days but then they get hungry fast for p-k due to the intense growth after the flip.

Thank you, I’m following a nute schedule made specifically for an aerogarden but it’s for one with a larger rez. The bounty model to be exact. It holds 4.1 liters of water while the one I use only holds 2.6. The nute schedule uses half the recommended dose on the bottles of nutes And I always end up over shooting the PPM when adding. Using schedule recommended Doses my solution is around 1200 PPM so what I do is just pour out some of the solution and as distilled water till it hits the 800-900 PPM. Should I try another way? This week called for a reduction in Flora Gro from 5 ml to 2.5 ml and Flora Micro and Flora Bloom stay at 5 ml.

Some times plants require a little more but they will tell you when they do.

 

[Fantomlimb]

Do you think I should adjust doses to half since the Rez only holds half of the water or is emptying some of the solution and adding distilled a good method?

 

[Stormblessed]

How much water is in there?

 

[BeanTownFan420]

From what i see they do need higher dose of feed start slow see if they begin reaching.

 

[Stormblessed]

Nvm I see it now

 

[Stormblessed]

Any picture in normal light?

 

[Fantomlimb]

What should I add more of? Micro, Gro, or bloom and how much? What PPM should I shoot for? Sorry for all the questions, I’m completely new to this.

 

[Fantomlimb]

Also I don’t add nutes throughout the week. I fill Rez once and add distilled as it gets used through out the week. Should I just make a big batch of solution and use it to add to the Rez, or continue just adding water till the end of the week?

Here’s a pic with just the sansi lights and one with none of them.

It looks pretty healthy other than the slight droopyness, my gelato seems to do the same thing, so I’m curious the answer

 

[Fantomlimb]

Lol me too, I unfortunately don’t know the strain as I got it from a random bag.

Looks like a case of wetfeet to me. Are those roots completely submerged? Is it possible to drop the level in your res?

 

[Fantomlimb]

They are completely submerged Except for parts that either have grown up out of the water or when the water level gets low. The aerogarden is a mix between a DWC and a drip system. There’s about an inch gap between the lid of the res and the water.
