So I have two northern lights (so I've been told) plants going. Both have been in flowering since the end of October. One is doing real well the other is getting yellow leaves then they turn brown and fall off. I put the light up higher around 1 and half feet above thinking it might be light or heat stress. It does seem to be stunted a little bit. Can anyone help? They are under two 300w LED lights and are in 7 gallon grow bags.
Pull those dead leaves off its taking energy from buds Sent from my SM-J327P using Grasscity Forum mobile app
Fox farms is packed with nutrients ( If you're using ocean forest) but by now its probably already been used up, how heavy are you feeding?
No, it'll just effect more leaves. Whatever nutrients she can't get from the soil she's gonna take from her remaining leaves. You can pluck those leaves but imo I would leave them until she sucks them bone dry while you fix the problem in the soil
Now if it gets really bad you might end up losing a week or 2. Deficiency late in flower could hault the progression of flowering especially if its early in flower. It shouldn't be something you can't fix. Test the p.h and ppm of your next run off and that should help you get an idea of what's going on in the soil
My plant had similiar issue and mine was due to salt build up. 1 20litre flush later and she looks alot better. Sent from my SM-N910C using Grasscity Forum mobile app
