while yellow leaves could be caused by alot of things if the problem starts with the older leaves and works its way up the plant it is usually nitrogen deficiency wouldnt worry to much about the very bottom leaves but if it continues to spread would probably feed them usually if you have decent hid lighting and grow room the plants will be able to handle full strength nutes by the time they are 3-4 weeks old while you should start them out at reduced strength just to see how they react.
bejay Reviewed by bejay on . Nute burn on a 10 day old? Here's 2 pics of my plants, there's substantial yellowing on some of the leaves. They are growing in compost designed for tomatos. They are off a 400w HPS lamp, watered every 2/3 days depending on how dry the soil is, no nutes are being added to the water, they are on 18/6. I don't really want to flush the plants but if thats the best course of action I will do. Any ideas guys? Heres some images of the two worst affected plants so far. Cheers guys:thumbsup: Rating: 5
