Pulled this of my plant today, just a couple of these guys on the plant, iam guessing its a phosphorus or potassium def. Does anyone know what it is and how to correct it?
 
could be a number of things and without an accurate info on other growing factors then no accurate diagnosis can be given...

so in other words cant tell you if its turning purple either from temperature differences, or there is a lock out of phosphorus from pH, or a deficiency...

so cant accurately give you an answer...
 
1000w hps....7 gallon fabric pots w/super soil.....daytime temps 75-80 humidity 45-50 nighttime temps....65-70 humidity 50-55.......soil ph is about a 7
 
if its just a couple of leaves i wouldnt worry about it, as discolouration of the leaves happens later in flowering as the plant starts to eat up the nutes in them...

if anything jjust give a dose of phosphorus and wait a week and see if that doesnt take care of it...

good luck and enjoy the grow... :)
 
As i look at the plants more and more, its def a phosphorus problem due to the soil ph, you were right crazy....so i think iam just gonna give it some phos when i water, hopefully that helps it thru the last 4 weeks.

peat moss or low pH water may help it out a bit.
