Just noticed that over night one of mt lowryder plants has develped some yellow/brown fan leaves. There nearly 4 weeks old and had no nutes yet so i was thinking some kind of deficiency maybe? There are a few leaves that look like this, there yellow at the tips and have a few brown spots at the tips as well. Any ideas what this could be? Thanks.




Just noticed that it looks like i have loads of plants in the background lol. Well it's not only have the 2, it's a tree outside in the garden lol.

I made another thread early on but no one has replied so i'll link it here since it's related. Nutes just boggle my mind the more i read about them the more confussed i get. https://www.rollitup.org/newbie-central/98034-nutes-lowryder.html

Be careful lowryders dont need very many nutes i doubt its a deficiency. What type of lights are you using? What are the temps? Whats the ph?

Lights- i have a dual 125watt cfl.
Temps are 75.
Have no idea what the PH is don't think that is the problem though cos i let my water stand for at least 24hours and then add a couple of drpos of lemon juice to bring my ph down.

I'd start nutes...slowly...plus to me the leaves look a bit over watered. ..IMO...
whats your watering schedule ??
As for nutes..I stay basic... 20-20-20 for veg... 10-25-20 ratio for flower... all can be a bit +- , but I'd keep those ratios... Luck.

I water then about every 4 or 5 days when the soil is dry and the pots feel light. I got some organic nutes while i was out is this better than the mg? It's called "fish, blood and bone multi purpose organinc fertiliser." It has a NPK of 5.0-5.0-6.5. If this is better then i have no idea how much to give them so any ideas would be great.
