Hi Dudes. Not been on here for a while, but still hard at it!

As the title states I need some advice from you all.

A problem in one of the grow rooms.

PLANT....818 Headband

SEALED ROOM.

CO2

TEMP.... 29 C

HUMIDITY 65%

AIR POTS.

COCO

DRIPPER SYSTEM.

H & G A + B

CX REGEN A ROOT

CX GROWTH ENHANCER.

E.C 1.6

P.H 5.8

So to the problem. my young leaves have and are staying closed, the older leaves are good. but now also the Mother has also this problem now. and they are in different rooms, Nursery & Grow room. with different temps etc.




Here are some pictures to help.

This was taken in the G.room








These last two should show the problem more clearly. I will thank you for all your help and replies in advance. what are your thoughts.

Have a good one.

That humidity is low for a temp of 29 deg.

Hi Dansbuds.
It is only the new to leaves that are affected, al the lower leaves are normal. However I did and maybe do still have a little case of Thrips, have been treating them with pred mites both in the pots and all over the leaves. though I did not think it would be thrips because I had a case of thrips a few months ago and I never had that problem.

As these are just about to enter their 3rd week in Flower It sounds like hard to get rid of Broad mites. How did you get rid of them ???
Many thanks for your reply

Hi Moses. As I am just entering the 3 week in flower I am in the process of lowering my stats.

the humidity was at 85%, I find that if I keep my humidity high for to long they don't like it.

But I am always open to ideas and suggestions. what would you put the humidity at in flower ??? remembering that I am sealed and running co2

And when would you start to lower ????

Many thanks for your input.

Do you have fans blowing hard onto the plants? that can make the leaves taco as they try to transpire to cope but so can having the lights too close and also Iron or Mg def.

75% for that temp. Try keep it within VPD parameters. It could be bugs as DB suggested, in any case 29C is a high temp environment needs to be on point!

Hi Spaventa.
No I don't have the fans blowing hard onto my plants, as they are on the wall at a distance and only on the 1st setting.

I have given them Cal Mag to no effect, so I ruled that out.

Lights to close.... Now that might be worth a check, they should be around the 14" to 24" distance, but again I will check, I also will check my canopy temp again as that could now be to high, maybe.

Also, this is happening in two separate rooms, this is happening to my Mothers 818 also, in my Nursery room where all my Mothers are kept that is run the old style way, extractor etc.
also the temp is kept at 75 the Mothers are also fed differently

E.C 1.2
P.H 5.8

Thank you for your help.

Very good point about VPD I am going to brush up on that and see where I could be going wrong, as when VDP is concerned I sure I am!.

I am starting to think Bugs of some sort, Because this problem is in two separate rooms, whilst I can have it wrong on both accounts it would be unlikely, my other Mothers do not have this problem, but did obviously have a case of Thrips!

In the picture I see white hairs, pistils. If it was broad mites they would munch those pistils and turn them black almost like they were burnt by fire!
