Hello guys lately I had problem with this plant, Think Different, its 17days old in coco, watered with Ph 5,7 and added Cal-Mag, but when I measure the coco Ph few inches deep it says its 6,4 . Yestreday I spotted brown dot on fan leaf and another thing is that older leaves are kinda dark green even tho I used nutrients only once and with 1/4 strenght (General Hydroponics Flora Coco) it seems that it have even heat stress by the curled leaves but temps at canopy are 27C max, using 250Hps 60cm above.

I would start be backing off the N if your feeding .....also let the plant dry out real well between waterings ...maybe even add more perlite next time .....sometimes the soil takes too long to dry out ....causing those little distorted ripples/wrinkles in the leafs.....so less food....and let her dry completely out between waters
 
They look healthy to me pal, but dark green leaves purpleish stems and brown spotting normally means phosphorus deficiency, I had that not long ago, but I can't see it with yours, I wouldn't worry too much mate
 
Thanks alot guys, its the water probably ,true becasue I have her in 7 gal pot too so the coco is wet all the time,
And about the light how would you recomment the hight from plant isnt 60cm high or ?
 
250w hps and adjust a wings defender, but Im a bit scared to get her closer, dont wanna her to have heat stress or bleach, should lower it ?
 
I'd deffo lower it mate here mine it's a 400watt hps and it's about 30cm above the plants looks higher like as picture was taken above the lights, there's different graphs online to tell you how much away you should hang themIMG_2304.JPG
 
OOoh I see, how are your temps mate ?? I have there like one big tower vent and clip fan :/ but when I move it closer they will show that heat stres
 
I've got a really small fan, 400watt hps and a 120x120x200 tent and temps are perfect pal, I think you'd be sweet give me two mins I'll find that chart for you :) don't really check my temps just make sure it's nice and warm for them, as long as I'm comfy with the temp for a good five mins they should be fine in there :)
 
Should see a massive difference in growth now I'd say pal so make sure you keep and eye on the height so she doesn't grow too much and get light burn for you, yeah get yourself a reflector makes the world of difference :bigjoint:
