Hey fellow growers, this is my first time doin hydro and i am a little unsure about the present condition of my plants 3 of which are northern lights and the other Ice. The ice plant which is on the right to the rear seems to be doin quite nice, however the two i am most worried about are the ones on the left which i think are showing signs of nitrogen def, Sorry for the crappy pics but my phone was all i had available to me. the leaves seem pale and dry not to mention a bit droopy . the dark pic you can see browning from the centre of the leave outwards which is an isolated leaf and no others are like this at the moment. the new growth coming through is nice and green but has slight tinges of yellowing on the tips. i have them on 18/6 under 400w hps , nutes are 3/4 strength aqua flakes , PH is 6.2 -- 6.3 . I am using liquid silicon for ph up and acid for down temp is around 34 degrees FH and humidity between 30 - 60 % i also use a small thermostatic heater to keep the temp stable during dark as i grow in my loft and cold is a problem here in scotland. the temp normally sits around 15 degrees FH during dark , i was thinking the dry air could be contributing to the dry leaves but its only programmed to come on if the temp gets to low so i am unsure about that theory. any ways guys i hope you can shed a little light on this, cheers
