Nitrogen Mayday!

Nitrogen Deficiencies
Plants will exhibit lack of vigor, slow growth and will be weak and stunted. Quality and yield will be significantly reduced. Older leaves become yellow (chlorotic) from lack of chlorophyll. Deficient plants will exhibit uniform light green to yellow on older leaves, these leaves may die and drop. Leaf margins will not curled up noticeably. Chlorosis will eventually spread throughout the plant. Stems, petioles and lower leaf surfaces may turn purple.

This sounds exactly like what is happening to my plants to a T, but the extra nitrogen didn't do anything. It said that Nitrogen is best absorbed with a pH between 5.0-7.0 and I am 100% sure mine has been within that range.

WTF???:wtf:

DJ - there is a big part of this concept that you simply are not grasping. Read this thread:

I didn't get anything from that...?

Ok, so after reading it all again, all I got was that your pH climbs back to 7.5 pretty fast and throws things out of whack, but I don't have that problem. My pH goes up about .3 over the course of a day. If there is something I didn't grasp from that thread, please fill me in. I will admit that I only read to page 3 because it wasn't really pertinent to my situation.

I got CalMag Plus, so I will start using it tonight. I noticed it has a 2-0-0 on the front meaning it has some nitrogen in there, so hopefully things will turn around.

Well, it discusses nutrient lockout - but you don't seem to want to consider that possibility, so there's not much else I can suggest you do.

Good luck with your grow!

Sorry, but when there isn't anything that relates to my situation in the first three pages of an 8 page thread, I don't really want to read the last 5 pages. I understand nutrient lockout in relation to pH, but I am 99% confident that my issue is not pH related. The 1% is reserved because anything is possible, but my pH is very constant and something I keep a close eye on. If there is something else buried in that 8 page thread that I missed or am not understanding, it would be sweet if you could just tell me what it is.

Instead of changing the whole res, I diluted the solution down to 1400 PPM and then added 95 mL of CalMag Plus which brought it to 1750. I also did a foliar feed with my veg nutes. How often should I do the foliar feed? I tried to keep it to the leaves as much as possible and keep it off the buds. Hopefully things start turning around, but if not and my sick plants happen to die, would the buds even be worth saving at only 4 weeks?

I found what you were talking about deep in page 5, with the high PPM causing the roots to "shut their mouths". I knew a little about this from reading about PPMs and how if you get it too high, the plant can't take up enough water and things get locked out.

I also found this interesting:

Looks like we are in the same boat here, buddy. :jointsmile:

I don't know where you are at on this, but that jackerspthingee was right. 1950 is way too high for PPM for most all strains. Try about 1400 or so and see what happens.
