Hi am a new grower an just joined for a little guidance an information.. am in 1.5x1.5 x 2.5 tent, 2x 600w hps lights. Using coco/hydro in Wilma, feeding 3x daily when lights on... I’m at about 80 ltrs of water in res, I’ve added 4 spoons of green house powder feed short flower, 60 ml canna boost, 60 ml of of a pk bloom booster callled sted head an a spoon of molaasses.. also I’m at about 700ppm/1.4ec an keep my ph mostly at around 6, am at a range of 24 to 28*c an humidity range of 30 to 50%

My problem is that the tips of my leafs are curling down words an have been since I switched there inviorment to my flower tent. I’m clueless as to why ? i have 3 pants an it’s only on one plant an slightly on the other, but one is fine which is very confusing !!! Just wondering if anyone has had this problem or any advise

Drop it down to 1.1ec they weren't ready for 700ppm. I've also found my plants are happiest in coco at 6.3ph.

There in the 4th week flower an one has been curling since week 1 when they were on 0.6/0.8 ec. An would it not show if they were burning on the leaves ? Thanks for the reply

I need pics to help you any further bud. I could be as simple as they're getting beat up by a fan.

Are they root bound? That's some serious stress for a plant in flower. Better check for balls to be on the safe side.

Defo not root bound a I dint see how it’s so stressed as the one next to it’s fine I was thinking it could be co2 coz everything else seems fine
What effects would lack of co2 have ??

An thanks for the advise

Do you have an active or passive intake? We're going to have to start process of elimination.

I doubt it's co2 with a 6" intake. Are you pulling the air from inside or out? Even if your pulling it from inside, there should be enough co2....

I think this if going to be directly related to that plant. The other plant doesn't seem so bad off.....
Keep posting info related to your setup.

With hps 21-28c, I had to hit Google to convert that, lol. So you're right in the middle...... You say you're feeding 3 times a day. How much is the coco drying out between feeding? I overlooked that detail, and I think we're narrowing it down now.

So what I think is hairline is that plant is getting over watered. If the coco is still really wet when hit it again is most likely the cause. Let the top layer of coco dry out, at least 24cm, or around and inch. Then a through feeding and repeat.
