Buddy's plants problems

[Dividedsky]

So was just on a live chat with my buddy...he is trying to figure out a problem with a few seed plants. All of his other plants in the flower room look fine...even the same strain of said sees plants. Wanted to see what you guys thought. I was thinking a calmag or N deficiency but I'm not sure. He usually runs a sealed room, with co2 but think he has more of passive setup now in winter. He runs 4 -630 cmh in bloom.

how close are the lights ?

I'll ask but he usually keeps thing at the average distance, I'd say even higher than most.

 

[Dividedsky]

I'm actually starting to think he could be under-feeding because his ec meter broke so he's been feeding them light to barely any the past few days until he get to the hydrostore to snag a meter. The weird canoeing could be heat or light stress but his temps are good. I was thinking nute-burn but according to him he's been barely feeding so I don't know, looks strange for underfed plants but then again I've seen hungry plants do some strange things.

So just talked to him- my bad they not under his cmh yet, they're under t5s in veg still so don't think it the lights.

 

[420burn420]

I don't think the t5s would cause it. I was just mentioning that because of my last grow. I had led light on full blast and had it too close. Maybe overwatering or something along those lines. Check the levels.

If there is no heat problems, I would guess a potassium or mag deficiency with maybe too much direct air.

My guess is those plants were overwatered recently.

Puckered, wrinkly leaves that look like they were recently pointing downwards, with uneven interveinal greening. Purple stalks. Pretty classic watering issue.

Now the roots have been choked, so even a set of T5's just a little too close can be too taxing for the plant (especially if slammed right to the plant tops) so it tacos it's leaves and is drawing elements from itself wherever it can get them to rebuild roots and get going again. Even that lower heat that a T5 can produce, especially up close, can tax a leaf if that leaf can't get the water it needs.

If you choke / damp off the roots on a larger plant you effectively make it start over again with a root structure about proportionate to that of a seedling or young clone, but you still have the upper portion that requires a more robust system and wants to produce chlorophyll. So it does what it can to mitigate it (folds leaves up, translocates elements)

Thats just what I think is going on looking at all the different symptoms.

Best of luck.

Ya seems about right, he is thinking of reporting them so perhaps it won't be a bad idea.

Yeah it kind of all links together. Sometimes people are like "it's heat stress" or "it's overwatering" when in reality it's both, with one often leading to the other.

I've had my fair share of oversaturated plants, even recently in Hempy buckets, because I was getting the Rapid Rooters too wet. As soon as I stopped watering the Rooters, and only the perlite around them, bam, within a week, back to normal, thriving and nice green stalks instead of purple, never having given them a lick of nutrient boost. The entire recovery was just from the refraining from watering too close to the stalks.

Is he actually in flower already or still vegging?

Still vegging.. he has plants in flower but they're fine. So he might repot, seems their's a few phenos of this strain are just finicky as fuck and don't like to be watered to much....like to the point of runoff.

Thats most likely the problem EC meter, nuit burn.
