Yellowing lower leaves? Nitrogen Deficiency?

New Member
sup,im a first time grower using a standard potting compost in a greenhouse grow. I have some maxicrop organic fertiliser and have once used it on my larger plants. On near enough all of the plants the lower leaves including the cotyledons (which have died) have turned yellow and many of them droop. To my alarm this is also the case on most of my younger plants aswell. I'm pretty sure this is nitrogen deficiency but want to be completely sure, and am not sure whether i should add fertilizer to the younger plants as I'm aware youre not supposed to at this stage. Any advice? will try and upload photos shortly
cheers

Without more information, I would agree with your diagnosis. You could always "experiment" on one or two in order to verify.
