Hello,
First time grower and poster,
I have a 1.5m2 tent in the garage with a 600w hps, 1500w oil rad and 4 clones that are in the start of week two of veg. The first week I struggled with temps being too cold. Hence the rad now. Now sitting at 20-24c lights on and 18-20c lights off.
I woke up today to find the top of the plants leaves (see picture) looking different.
also I’m struggling to find the happy place to where I’m not over or under watering them. When I think they look good and healthy, I go back the next time and they look all sad and droopy.
Im not sure if I’m over fussing as it’s my first time or if I’m causing the issue.
TIA
Welcome to Percys Shay, is that plant in coco?
Hello, yes its in coco with perlite.
There is the problem straight away mate 
You can t over water in coco and you need to keep it damp all the time. Never let it dry out.
What happens is, as it dries, the water is drank by the plant, some is evaporated, and the food is left behind in the coco. This can make the EC spike, the drier tit gets thr higher the EC can be.
You need to be watering every day to keep a plant happy in coco and i think this is the cause of your problems.
What nutrients are you using?
How much of those nutrient per litre are you giving the the plant
Are you monitoring the EC/ PMM?
Are you monitor the PH?
Hope this helps mate. Tell me what youre feeding it and we can come up with a good idea of where to go from here
@macky Makes sense,
Im using Buddha nutes, Week 1, been doing 2L per plant every other day on average, watering and drying up excess.
Im Ph'ing the water to 5.8
Sounds like a lot. Good line though Buddhas tree.
Flower burst only really needs to be used on the last week of veg before you flip.
You're not using the organicus too right?
Id be looking at something like:
Meta boost 0.5 ml per litre
Solar Green 0.5 ML PL
And Coco A n B 2ml ML Per litre
That's correct, Flower burst last week of veg and no organicus.
They're the exact measures that I am doing.
Awesome lol!!
Ok, so now, I would flush them, to remove and excess salts, and then re feed them at their usual dosage.
Keep feeding them everyday, and don't let the medium dry out.
Also, make sure you're getting at least 10% run off with each feed, and drain the run off away too. don't let the plants sit in it.
Do that and they will start to look a lot better in a couple of days
How long should I flush for?
And yes been having roughly 10% run off and cleaning up.
Appreciate you're help mate
Just once mate to bring the EC of the medium down a little..... are you monitoring the EC at all?
You need an EC meter, this will tell you how much food is in the water. Can help tell if you're overfeeding or underfeeding.
Just give a big feed with loads of run off today then, make sure that coco is fully saturated. Then water every day from the with 10% run off I think you'll see improvements pretty quickly then
Because you don't have an EC meter, avoid giving it just water. Instead give a bigger feed, at the levels above, that'll help get the medium fixed and on the right levels
