need help with my girls

[boo]

I've posted pics of my leaf issues and got no reply so I guess I need to have a thread where I can hopefully get assistance with the demons...normal feed, pH, and yes, calmag at 6 ml./gal...any thoughts would be greatly appreciated as my frustration level is rising...

That first one looks hot to me boo. I’ve seen that before in my tent. how hot is it in there ? And what’s the RH?
the third one looks like a humidity issue. I’d take that one off so it doesn’t touch any other leaves. Sorry boo. I know I’m not much help… good luck with getting some answers.

My green crack looked exactly like. It was a root problem in my case.

 

[boo]

first pic is 20" away from the 600led, the other 2 in the same tent is at least 24" away...dunno what the RH is but I know it's pretty humid down here, especially in an enclosed tent...after watering the tent feels like a sauna...8" turbo fan exhausting and a 9" vornado fan in each tent...they all seem to get funky at about 5-6 weeks...I've opened all tents and am pumping cool air into all of them until lights off...spunom, elaborate on the root problem, I'm curious...
on a lighter note, I got the grove bags today, the look pretty nifty...

I wonder if you added some hydrogen peroxide in the water

 

[pute]

My first thought was heat stress. On the first picture. The second looks like a mag deficiency.

 

[RosterMan]

Been seeing more and more heat stress lately
My two plants that have it look like mutants now

 

[boo]

I believe hydrogen peroxide in the soil will kill off the beneficial bacteria...

pute, 20-24" from the light, 600 watt LED...top one may be heat stress but the spots purplex me...seems like the leaves are coppering...

If you are in soil, are you re-using the soil? I had a couple of grows go south re-using my soil because the peat in the soil breaks down and acidified the soil. Wish I could be more help…

I have reused soil several times in the past and never had issues like that.....hmmmm.

Yes it can

 

[spunom]

I had two things going on...

My water line was too high on my wick causing rot and fungus gnat larvae we're attacking the roots in the planter.

The plant showed signs of heat stress but it kept getting worse after I opened the tent up and raised the lights. Then I started getting light green between veins which progressed to the copper/brown patches. Once I lowered the water line, and got the gnats under control, the plant stopped worsening.

You don't grow the same way, and i know you know how to water correctly, so probably no rot, but could something be/have been hurting your roots?

You pH. I see boo does too so it probably isn’t that. The plants look all over the place. The first one looks like nitrogen toxicity maybe since it is so dark green and shiny. The others look more like deficiencies. My plants in the re-used(not amended either) soil got crispy, curly leaves.

 

[boo]

I NEVER reuse my soil...my thoughts on that is the soil finishes off in flower and I don't want those nutes in my veg plants...I scatter my rootballs all over the woods and crush them with the tractor...I see slight leaf curl from the light on the other 3 in flower but nothing like the first pic of fire OG x BB...flowers are stellar but the leaves are going to helll...I'm pretty confidant with my roots but I appreciate the thoughts...I have added flower stacker to all veg plants 2 weeks ago, 1 ml/gal but dunno if that's the issue...all other plants got it and are looking fine...

 

[spunom]

I wish I could be more help Mr. Boo, but I lack the knowing. You've helped me on my path in more ways than one, and I hope I can someday reciprocate it back to ya. I hope you come across the answer good Sir.

 

[boo]

thanks spunom, I've been out with the demonized tent and am pretty sure the lights are just too intense for the height of the plants, I'm still learning about LED's and their quirks...the top plant is the worst and the others are fine with the exception of a few curling leaves...flowers are stellar but dying leaves bother me...my area is almost 100% humidity so today I started opening up the tents and using an oscillating fan to help move the moist air...after feeding they live in wet air...once I move into my new grow and set it up that all should be history...odd that I have a 5' x 5' tent with 2 315 CMH light at 8' and the plants were looking stressed...shut one light down and the plants seem to be super happy with only 315 watts...I learn every day if I pay attention...

 

[Airbone]

Soil ph ok?

 

[boo]

last time I checked the runoff was 6.0...spot on as I feed at 6.2 plus or minus...I'm really thinking the light it too close but I can't do anything about that for now...4 plants are crowding each other after the stretch...that gorilla breath just takes over...

Might be those leaves are sweating under the bright lights. Is it possible to turn your lights down? I don’t remember but I don’t think you are using LEDs right? That’s how I fixed that curling in one of my plants. My tent gets really warm especially in the winter as it’s in my hot furnace room. I can’t run the lights at 100% in the winter. The gas heat doesn’t run in the summer so it’s a bit easier to grow in there then. But that first picture looks a lot like my plant that got to hot. Now add humidity and I think that third picture looks like wet hot leaves could look like that after a while. Blowing them out with the open tent during the day when the lights are on is probably a good idea down in your parts.
