Hi everyone, I’m a new grower needing some advice with one of my plants. I’m running a autoflowering northern lights from Seedsman in a DWC system with hipargero 800w 20/4 cycle lights, fox farm trio plus cal-mag (following their schedule for hydro half dose), ppm around 750. The plant is almost 8 weeks in from sprouting, my temperature is 26-30 graus and my humidity is unfortunately around 60-70% nothing I can do about it right now no money anymore. I start notice some yellowing in the bottom leafs in this last 10 days asked here for some advice and I was told to don’t worry it should be only some mistakes in the past that’s I did also lack of lights what’s made all sense to me but then now this yellowing keeps taking over my plant and it is looking different from the yellowing that was before. Will attached some photos. Please could someone tell me what’s that could be? I don’t think that it’s just from lack of lights anymore I believe it could be something else now. Should I increase my bloom nutes? Should I increase my cal-mag? Does anyone could share some info and experience with me? Thanks in advance have a good day u all
Bro feed your plant its eating itself and trim like 30% of those fan leaves that will help with nutes. Those leaves are using up all the plants nutes and energy and they are leaves its a waste. That girl is gonna need atleast 1000ppm creep it up 100ppm every 3 days ph at 5.8 should be if you notice brown burn on top leaves slow the feeding a little, ALWAYS MAKE ADJUSTMENTS SLOWLY. Slow and steady wins the race.
I still think you don't have a problem. It's natural for fan leaves that get little light to be scavenged by the plant, and it doesn't indicate a deficiency. I've had simultaneous nute burn and dying, lightless fan leaves. My DWC experience with autos is that their feed needs to be reduced late in flower. I got nute burn at 500 ppm this time in late veg, and am at 350 ppm in late flower.
Get rid of all that shit you got on the bottom. Anything not getting light's gonna die off like that... Careful trimming autos though, do it slowly, like 2-3 branches/day or like 5-7 leaves... They're day neutral and any growth-inhibiting stress may effect yeild more than usual. Edit: damn nice looking auto otherwise, though holy shit. Lol
There is some phosphorus deficiency showing but I think you need to lollipop that plant. It's not too late. Start from the bottom up and remove the parts not getting sufficient light. Indoor growing requires some shaping of the plant. Autos don't like it as much but you should still limit bottom growth. You would be surprised how much you can remove when you do it before flip and the plant will recover. I never remove enough and always end up with more larf then I wanted.
