Hi all, I have a lemon kush here that's just under 4 weeks old. I have topped it but the leaves seem to be drooping. They are quite hard to touch and curled under, anyone know why? And how to rectify it?

I try and water every 2/3 days and water between 1 litre and 2 litres. The pot is 8 litres so wouldn't of thought root bound? I have an 11 litre pot I can transplant into and check?

What light and how close is it? Are you feeding it anything? Are you foliar feeding/spraying?

I'm growing in canna coco professional and I started using a small dose of canna coco a + b but last feed was straight water just to try and flush it out if it needs it. I'm using a 400 hps, the temps are usually around 26/27c. I have it roughly 3 foot away, the leaves don't feel burnt or have any burnt tips

Bring your light down till it's 12-18 inches away from top of your plant, but watch out for heat stress. Place your hand over the leaves. If it's too hot for the back of your hand, then it's too hot for your plant.

How much exactly? You need to feed your plant regularly when growing in coco. Coco is a completely inert medium. It just releases some potassium while absorbing the available calcium in your nutrients.

What's your pH going in?

And always wait until the top inch of your coco feels completely dry to the touch before every watering/feeding and always water until you get 15-20% runoff. You can also test the EC of your runoff to see how your plant is using the nutes and prevent from salt build-up.

Ok I've got you, I've gave it a couple of feeds with 2ml of each in 2 litres of water but rest of feeds plain water. Do you think I need to be feeding more? The ph is between 6/7

I highly recommend that you get a pH/EC meter before going any further. You should always adjust your pH to 5.8~5.9.

For next watering, add equal amounts of Canna Coco A&B to your water and prepare a solution with 0.9 or 1 EC, then adjust your pH to 5.8 using pH Up or pH Down. Then flush your medium until you get 50% runoff. After that, keep an eye on your plant for the following 3 or 4 days and see how it reacts and update us.

Ok thanks for the info! - I have just transplanted into a 11 litre pot, the roots had covered the whole of the 8 litre pot. Gave it some a + b equal amounts and see if reacts but I will take your info on board 100%

In coco you need to feed and water til run off every day, its a hydro setup and must be treated as such. Do t treat it like soil or you will fail. Dont be worried about watering daily coco holds plenty of air for the roots even when fully saturated with water. Be sure to ph to 5.8, feed plenty of calmag and feed/water daily and ph water only once a week to prevent salt build up. Plant looks hungry as hell to me, needs more nutes for such, N starved.
Canna Coco is good stuff, its the only n ute i would use if and when i do coco.
