problem

I have got a reoccurring problem, I believe is mg def, it starts on the lower leafs and the tips and works its way in, I have flushed with clearex, I have flushed with flora shield. This is bag seed and they are very light green, I am using very weak nutes and a little espom salts. temps are 76-78 lights on and 70 lights off. the leaves got real yellow and brown so i trimmed and flushed. now after nice new growth its starting again, any help please?

bump......

nitrogen is the problem when your plants are turning yellow like this its not getting enough nitrogen

what nutes are you using and how much?

Those look like identical to my plants. Its not N or magnesium. Its Potassium. U can tell from the outer tips of leaves being burnt. I'll guess that ur using FloraNova nutes?

Thats right...research!!

Not trying to steal thread but would it be best to leave the yellow leaf on there until its just completely dead?

thanks for the input everyone, i am using botanicare power plant 3-1-4 and whatever the plant is missing seems to be locked out, because i am feeding it.
