Hi guys, I was wondering if anyone has grown Nirvana's Northern Light (Reg) before in DWC ? . I am on my 4th DWC grow and am still experiencing issues with what is claimed to be one of the easiest strains in existence to grown indoors. If that's the case then I have no clue what so ever what I am doing wrong here. On my first run with this strain I had posted here with issues back then with nute burn and the plant adsorbing too much salts, damn thing was dehydrating itself and leaves turning yellow and clawing up to a brittle state. The thing that got me was I never went higher the 500ppm the entire grow. I ended up milking through that harvest by flushing her like crazy before harvest. I ended up with over 6 ounces but it ruined it with overfeeding and salt build up and even with a long ass cure it still burnt very bad would not stay light , crackled , etc .. no smell, bad taste , did have a nice buzz but if I could have got things straight could have been nice.
After that I ran the strain Holy Grail 69 and it went very smoothly , hardly any issues what so ever other than a slight N tox that I dealt with quickly. It came out great! Then another strain " Berry White " I believe is what it was called and again very smooth run all went as normal, both these yielded around 5 - 7 ounces each. Now here I am on run #4 and back to Nirvana NL for a second go at it since I was very impressed with the yield even though I destroyed that damn thing , it still put off ALLOT for a single plant. So all was smooth at first then several weeks in I started to notice the leaves starting to claw down a bit and start curling under and getting real skinny and thin from this curling before then turning yellow and dying. I noticed that the leaves were also getting very dark green so I thought again from last experience with this strain I am feeding her to much again but no tips turning brown like before just seemed like a N tox issue this time. The thing is this was approx 8-10 weeks into the grow from seedling and my ppm level was under 150ppm when it stared acting like it was being overfeed which is stumping me to no end. I grown in a single 6 gallon DWC bucket with a 10" net pot and a 6 Inch flat air disc / stone with a commercial pump with expandable clay pebbles. I assume all is good there.
During veg I start with CFL's that I finish most of veg with at around 368 watts. During finial weeks of veg I move to a Mars Hydro 600 LED ( 280 real watts ) . Once I move into flower a wall bank of floro side lighting is added with approx 180 watt from side lighting and by mid flower I also turn on 2 more Mars Hydro LED 300's ( approx 270 real watts total ) that takes me to around a little over 700 watt of lighting. The room is well vented with exhaust and temps are kept around 74 - 78 degrees and 60-70 % RH. It seemed to be dialed in pretty good for the other stains. I only grow one plant per run and do an extended veg to get her as big as I can before I go to 12/12 , then Scrog it when starting the bloom phase. Once this problem started I already had her in the Scrog and had to remove it from there which was a total PIA just to inspect the roots as it seemed as if perhaps this was a root issue. But roots are nice and cream color, healthy and huge , no signs of root rot, etc. So if no root issues how in the hell can this plant as old is it is burn @ under 200ppm of nutes ? With all its getting from environment I would assume they would be eating at very least 500-600ppm by now , but I am certain if I feed anything more than 150ppm right now they would fry. Same as the last NL run ..extremely low nutes for some reason they seem to like is what I am getting , at this rate I do not think I will even get near 400ppm for flower even without seeing issues and signs of nute tox. I am starting to wonder is this normal for this strain to actual prefer that little of nutes or is something bigger going on here that I am not seeing ? I was going to start flower a week ago but have held off and am still vegging till I can get this problem under control before switching. Any help is much appreciated guys n gals, thank you in advance.
(BTW. I run Dyna Gro .. Grow, Bloom, Pro-Tekt, Mag-Pro )
