hey im growing a coupler plants on my windowsill there about a mouth old and have started 2 get brown spots on the leafs could anyone help me out plz
I see this post is from along time ago, but did you ever figure out the problem? I grow under FL for veg and CFL for flowering and I started putting my plants our to veg in the sun at about 80-85 degrees outside temp and they started to curl, yellow and brown on some leaves.
Hi i am just wondering how u made up ur weak solution to spray on ur plants when they were nutrient deficient i have just noticed one my leaves r starting to turn and i want to sort b4 gets worse thanx
would you say 4 weeks old is too young to spray with fert ?
no answer ?
Don't plan on getting one... I've had tthe same problem on EVERY plant... Not yet a correct answer. I've had to figure it out on my own!
check under leave for spider mites or your locked out check run off ph mag all the normal if not flush
lol look how many people asked the same question on this thred
answer to all the questions. red stems and leaves curling upwards is mag def. red stems and leaves curling downwards is N overfert. brown patches or spots with light coloured leaves is underfert N P K levels are too low. brown spots are an indication of potassium def. just add fertiliser with a good npk ratio. 2.1.1 for veg and 1.2.2 for flowering.
Holy fuck lots of misinformation here. Brown spots can mean LOTS of things. Most common is calcium deficiency. You can't accurately diagnose a plant without seeing pictures.
One thing you also have to watch out for is "bloom" nutrients or nutrients formula's for Cannabis having too little N during the flowering phase. I used to get the yellow leaves by week 3 with straight bloom formulas, best to keep the N higher until at least the stretch is over. Best of luck
Brown spots WITH yellowing and dieing off leaves. Most commonly N def, could be Cal def but most likely N def.
Hey Can anyone tell me what the problem with this girl is ?
There are little brown spots on the leaves
Be careful in diagnosis...overwatering, the MOST common mistake made by beginners, can also cause some leaf spotting and yellowing.
