I just recently started my DWC res I got a decent seedling I have been growing thats feminized Ice Kush I am planning on cloning once it gets big enough. I am extremely new to growing as well I posted awhile back about the set up I was making. I have everything set up seedling is grown large enough to put into the res.. My problem is that after being in there 3 days its beginning to have light green and yellowish leaves. The biggest leaves are not only turning yellow but have brown spots in the center as well. I dont think its too much light as I have a 400w hps thats about 8-10 inches from the plant. I did recently start its 1st week of nutes I am using the Foxfarm nutes I set up 5 gallons worth using the tsp per gallon measurements. Ph is 6.5 a little high im sure.. I also have the drip tube pretty close to the plant in the medium as you can see in the picture I am about to post. Whats your opinion? too close to the light? too much water? too soon for nutes and possibly nute burn or PH issues? Thanks in advance I have read on what the possible causes could be but I dont want to make too many changes and not be able to single out what exactly is going on.
Let me know if you would like more detailed pictures of the set up or if you would like a better pic of the plant..
To play it safe and from what I read you want to use more of a 1/4 nute mix rather than the whats reccomended so I cut the nutes down to 1/4 just now I also put a fan in there in case it was a heat issue.
I moved the light up anyway and like i said earlier decrease the nutrients I used.. The leaves that had the spots are now withered very badly. the rest of the plant looks okay I am hoping there is a major improvement tomorrow..
