leaves curling upward ?

[jayboss1]

hi all

just over 2 weeks on veg ,leaves curling upward ,

not to close to light & not dry

just been given week feed ,A+B -RHIZ -CANZY

 

[jayboss1]

what you think jon ? its not serious ,

 

[harris hawk]

Might have a "heat" issue , what is your distance from top of plant with light and what type of lighting are you using?

 

[Nizza]

less food prolly 1/2 what u gave

 

[jondamon]

Initial thoughts are humidity related.

But with the severity of the curl it could also be BROAD MITES.

Google "broad mites" and then check your plants over with a 30x-100x scope.

Another thing to do is place your temp/RH gauge at the plant level and test hi and lo for 24 hours.


This will help me to determine environmental factors.

What EC are they taking?

0.8?

[jayboss1]

cant see it being mites ,I give the room a good bleaching before they went in ,clean ,but will give it a check over ,not heat .

 

[jayboss1]

meter is set at same level as plants ,RH is 47% TEMP is 82.7F

Again I reiterate place your gauge at plant level and test for 24 hours.

Post your results if temps hi and lo RH hi and lo.


Is your oscillating fan positioned to close?

Are you getting radiant heat from the light?

Is the radiant heat causing a loss of RH at the leaf surface?

Broad mites are VERY VERY SMALL and unseen by the naked eye.

im not actually E.C them yet ,as only giving small amount of water each time they looking dry ,like every other day or 3 days ,

A+B
CANZY
RHIZ
like I say a week mix

IMO...you're over feeding and apparently started too early...and it looks like alot of peat in that soil wich can be acidic and maybe too acidic for your plant...I would transplant...and stick with the basics in veg when introducing her to nutes (wich is apparently too late...lol) and get an NPK value of like 10-10-10 across the board and start with small doses...g/l...

OK... you need to water the plant "Through" it must drip out bottom...
If you only water, as you say when they look dry, most likely, your soil at bottom of pot, is bone dry, and the roots can not find water....
If you continue to water as you are, your plant will stop growing, and not grow a great root base...
Good Luck...

Def heat related, look how the bottom is not doing it.

 

[jayboss1]

its canna coco professional soil ,im only mixing a light dose off

A+B
RHIZ
CANZY

just a small amount to 10ltr bucket of water ,I have just raised the light a bit more ,I will keep my eye on em

Good advice.

I have always been told:
Leaf tips curling up-- Heat/Environment/light/wind issues from around your plant
Leaf Tips curling down--Water/Nute/Furts/ issues from within your plant

Good Luck Man...

 

[jondamon]

By only using a small amount of water each time to water them you are creating a high salinity environment in the rootzone.


My plan of attack is
Mix up EC 0.6 feed at 5.8 pH.

Water each 11litre pot with around 5 litres of water.


This should help to remove any salt build up in the rootzone.


Then just start watering normally.


Didn't I already tell you in PM's that small amounts of water without creating runoff is bad for coco.

[jayboss1]

you sure did mate ,and I know about runoff as you know and E.C .& PH .,I do this in my other room with my other plants with great precise ,this room is veg for my young uns ,its allot smaller and not kitted out for catching runoff yet ,iv just been using small trays at the moment ,but its a pain in the arse catching runoff in small trays ,can be a Burdon.

Im expecting a delivery today for a 1m x 1m garland deep tray ,and I have made a frame about 10 inches high so it sits on this ,plants will be set out on the tray ,then I can start doing my runoff ,soon as I get my deep tray im going to drown them bitches .

That's heat stress IMO
