Is my plant ok? Droopy a lot of the time, Dark Leaves

Gday all,


Just wondering if you could give me some advice please, I'm a first time grower so I may be looking into this too much.


Environment: Indoor Grow
Seed: Nirvana Northern Lights Autoflower (Feminised)
Age: 40 Days
Lighting: 1 x 300W LED + 1 20W CFL (Warm) + 1 20W CFL (Cool) (other 2 CFL's you see on the right aren't going to be used until plant 2 is bigger).
Ventilation: 4" Carbon Filter Inline Exhaust, 2x 120mm computer fan intakes
Temps: 22-28 Celcius
Humidity: 40-60%
Medium: 50% Peat Moss, 20% Perlite, 30% Vermiculte, Small spoon of dolomite into mix before planting.
Pot: 11 Litre/3 Gal Pot
Nutes - Vegetation: Thrive general purpose chemical fertilizer (half dosage)
Flowering (Just switched today) - Canna Terra Flores (4ml per litre of water)
Watering - ph 6.7 rain water (I run off water tanks here). Whenever the top 2-3 inches of soil are dry and crusty but feel damp just below this level. This usually happens about every 4-5 days. I use Nutes every second watering and use plain water otherwise.


I'm not sure if the leaves are too dark, they seem darker than most pictures I've seen. I've read stuff like Nitrogen Toxicity, Overwatering (don't believe this is the problem), Underwatering (don't believe this is the problem either), Nute stress (possible but unlikely as no yellow leaves?), Light Stress (don't think so as leaves aren't going yellow).


The leaves tend to droop a fair bit most of the time but are quite erect a couple of hours after watering. I've been letting it get quite dry before watering again as most have suggested so I would understand a little droop before watering but not most the time.


Originally the plant was in a smaller cupboard with bad airflow in the tin shed. This got really hot in the daytime so I moved it inside into the cupboard you see in the photos here. It has been in the new cupboard for about 3 weeks.


Perhaps I'm just stressing over nothing but you know what us first timers are like.


Please set my mind at ease or assist if you see an issue!

They look a touch overwatered in your pics. I would certainly not increase the fert rate at all, maybe ease it back just a touch. Otherwise I think you are okay. I would want to know that my soil mix was in a good ph range too. That peat moss is pretty low ph so not sure if your lime was enough.
 
Thankyou for your reply. Overwatering seems unlikely as I only do it every 4-5 days, is that possible still? They were just watered yesterday.

Does the colour seem ok? Should I be manipulating the plant at all or just let it go?
 
Well, it has a little bit of the curved leaf structure you see in over-watering but that doesn't mean it is over-watered. Too much Nitrogen will also do that and that is probably the case if you think you aren't over-watering. But not burned yet so just easing back a touch and moving them onto flowering nutes is good. I would just watch your nitrogen levels on anything you feed and check your medium ph just for sanity. I hate to even mention ph but I personally want to know what it is just in case it is off. Difficult to remedy at mid grow so probably most important to know for setting up your next grow. Might be just fine.
 
Begging for Nitrogen? Excuse my n oobness, but isn't nitrogen the highest concentration through vegetative stage and I hvae been giving it high nitrogen nutes. That does not seem correct.
 
The last thing she needs is more nitrogen! As Bugeye says she has maybe just had a bit too much.
Give her any more and you will burn her. In general,autos dnt need as many nutes as regular plants.
Too much N in flower will result in smaller buds.
GL.

I think you answered you own question right there, too much N.
