Sick P\lants

Greetings all, i've finally gone back to growing my own weed after a 10 year break from it. But I seem to have hit a few probs I wonder if anyone could try and help me diagnose...


OK, growing in soil (biobuzz lightmix), plants are 3 weeks old, under 150watt envirolite. Originally fed on a weak solution of formulex, a week or so ago I moved over to bio buzz grow, they had a couple of waterings with the recommended 5ml in 1 litre water, and then I started to see some probs. At first I thought it was nute burn, so they have been on water ever since, however the problem is getting worse, attached pics.. please help!

Yeah agreed, I just repotted and the roots didnt look to healthy, guess ill give it a week see where we are at

Stop feeding them, the new growth looks still okay so just water from now on until the new growth is reaching for the light instead of curling/taco'ing away. How close is your light as well? People recommend to put cfl's close to plants, but you still need to keep a reasonable distance (especially with large bulb sizes). I use similar pots as startes and as soon as the second set of leaves are in I repot. IF you want to feed them at this stage, get a rhizo based feed (rhizotonix from Canna) for example.

Good luck,

The plants are an inch or two below the bulb, I have repotted them, the roots were really bunched together, im wondering if maybe they just havnt been able to absorb the fert anyway, it def looks like a nitorgen def, as the older leaves start first, go yellow working inwards... anyway, repotted, lets give it a few days see what happens

That looks more like a nitrogen deficiency rather than burn. May even be a bit short of magnesium also........

Repotted, re fed, almost a week on, all is now well, thanks people!

rootbound ...

They are looking much better after a repot and a weak dose of fert
