Hi guys
So this plant was recently put under my new hps i am noticing lots of wiered things happen to the leaves, its on 18/6 and dimmed to 400w becuase there is some seedlings in there. The leaves are mostly droopy when lights on and off, the edges of the leaves are sort of crinkly/not straight then today on a upper leave i noticed a bunch of black burn like dots. I ph my water to around 6.5 and i using bloom nutrient watering Maby every 3 days at the moment. Can anyone help me why she is starting to look sick ?

What's your temps and stuff? Sorry when I said you need to water more I mean. Are you doing Feed - Water - Feed - water? Or Feed - Feed - Feed - water? Do you split your nutes? How far away are your lights? Noticing your growth pattern on the plant I guess you never trained or pruned either?
 
I water with nutrients mixed in till i get some run off then i wait for the soil to dry out and then again with more or plain water depending, im using plagron bloom at the moment. Yeah this was a plant i started while setting my tent up didnt get round to it , i tied it down today to try spred the light to the other nodes
 
Heres some closer photos

F80M4 asked two important questions - What's your temp and RH, how far are your lights from the plant?
 
I feel like your watering too much at a time. Those brown spots on the edges of the leaves lead me to believe that.

My Temp is around 24- 28 at lights on and then around 18 - 20 on lights off im running lights at night to combat the cold, RH is around 50 give or take I have a humidifier in the tent also

OK, sounds like you're ok there. How close is your light to the top of your plants?

I would say around 30-40 cm from the top part, after doing some research could it be a magnesium deficiency because I am just using bloom nutrients , I would think my tap water has enough in though, im not sure going to go check the tent now its lights off

You think ? Its an auto flowering strain glueberry og , I would more say its in preflower and has is stretching around now and is neally finished, ie the clock starts from the germination and now the time for it to grow in veg is over, my soil is prefertilised for the first 2 months (plagron batmix) so I didnt see the need for a bunch of nitrogen based fertilisers

Lights are a little close and might be causing the crinkled edges. As far as watering, make sure the pots are light weight before watering. Sometimes the top half of the soil is nice and dry but there is still plenty of water down lower. Those spots may be a calcium deficiency, try some cal-mag.

Okay thanks I will try this, what do you think is best I have 2 seedlings under this light aswell in the same tent but Ive been reading HPS is no good for during veg or can i just leave them in the same tent ?
 
From here it looks like under watered. Too much light or heat in low RH. Spots appear to be toxicity probably from bloom nutes. Correct these. Leaf edges are curled. Under watered. Leaves are curling. Not drooping from over water. Over fed. Spot are interior necrosis of purple or black/
. P & K toxicity. Would be even purple across leaves if deficient. Hope this helps. Best wishes.

Thanks for your post thats pretty informative so would you suggest watering with plain water for a few days, I would say the leaves are taking more of a yellow/light green tinge, should I feed one watering with grow nutrients to try get some of the colour back into the leaves or just best to try focus on flowering now

My suggestion would be my favorite 1 Tbs fish emulsion to a quart of water as a foliar spray for 2 days. And get a veg fert. Low P & K. Tose spots are permanent. Fix the new growth.
