Dude I wouldn't stress about that yet as it might not be anything. Just monitor it, If it is a deficiency you will still catch it early and be able to correct it.

How many days have your leaves been curled like that for?

checked on them lastnight at 10pm, today went to work so looked at them again at 5.00 pm and they looked like this. but they do get fed every day at 10am for tem mins by timer

have you looked into it being a magnesium Deficiency? I read about people having leaf curl and fixed the issue with a 1/4 tsp epson salt.

Also too much wind for prolonged periods can start to dry out the leaves causing them to curl.

i have got a osolliting fan blowing on plants, ok will try 1/4 spoon of sault, what will that do?

It has to be epsom salts and apply a 1 teaspoon per gallon dose. Look for a product that is high in Iron.

And i have ?!?
What temp is better for veg and preflo and flowering?!

those leaf tips are early magnesium deficiency, most likely caused by ph being off etc. but u say your ph is right so maybe try the epsom salts

right i started with nute burn about a week ago so flushed with tap water ph 6.2. left for two days, this is the 3rd day of feeding them for ten minuites drip irigation. 140L resi, ph to 6.0, A n B canna coco 50ml and 20ml ata atazyme.

Im running 1x 600w powerplant bulb, temps right now are 77.1f and steady hunidity at 55 -58, still in veg for 3 weeks so temp rarely alters apart from when hot outside it can rise to 82f.

If you are growing in coco and using canna nutes you are causing the problem by flushing at 6.2 ph. 6.2 is the maximum ph for canna coco nutes... Drop you ph to 5.7 to 5.8 and flush the fuckers for 2 days then give a good feed...., You dropped your Ec to .3 may i ask why ? In coco i wouldnt go any lower than .7 and if they are babys just use boiled and rested water with a ph between 5.6 and 5.8 till they can take weak nutes

A week feed using canna coco a + b is 1.5ml per litre.. And going off your resi and nute description of 50ml per 140 litres is way too strong... thats 2.8ml per litre... I dont go above 2.5ml per litre and i dont get to that stage till the 4week of flowering... 1.5ml to
2.0ml per litre should be all you need till you get to flowering...

2 remove the chlorine from ur water u don't need 2 boil it as long as u leave it setting out for around 24hrs I believe the chlorine will evaporate from the water, it is chlorimine and fluoride that will not evaporate when left out. But I'm probably just stating the obvious.
