I'm 30 days into flower and my plant is a rather light green in colour she has been like this for 3 weeks just wondering will one dose of nitrogen cause any problems I'm giving her bio biz grow at 1ml per litre total 6 litres every 4 to 5 days or shall I leave her I can put a picture up in the morning lights out now
wouldn't of thought it will cause problems..... unless you give her so much it locks out everything else. they tend to get lighter in flower anyway and better to be n deficient at harvest for best flavour (or so I was told)
Phosphorus in flowering will be better than nitrogen. I do nitrogen in veg then a good flush and lime to balance pH in pre flower. Then phosphorous in flowering. Just my opinion.
Too much N in flowering which I have just found out is very bad, N toxicity causes leaves to claw up and burning.
post some pics, could just be that they naturally lighter in flower. I had 2 plants indica was really dark green all way to end (smoking it now and really nice stone) and the skunk is really light green but otherwise healthy, slower flowering but its a sativa
