Im having some yellow edges on my leafs ( see pics ) . Is this caused by some deficiencies ? My plants are 4 weeks old and 4 days ago ive transplanted them from 1 gallon pots to 5 gallon pots because they where droopy . Ive flushed this new soil because its strongly fertilised . The soil is still a bit wet i havent watered them the last 4 days . I didnt gave them any nutes so for . Im growing with led 600 w in 4 by 4 tent . So heat cannoy br the issue and i cant see any bugs . Could this be a lack of nutrients , because i kept them in the first soil for 3 weekd without giving them any nutes .
