Question about dark spots on newer growth

[Stick E Fingaz]

 

Ok so here's the deal, had an emergency at a buddys house and had to move plants to another location. The thing is they have had to be kept in the garage most of the time except about 4-6 hours a day. There is a nice sized window in the garage that sun light gets through that they have been setting in front of, I know its not the same and I know that the heat and humidity in the garage is not good for them either. They have had to deal with these conditions for 6 days but are now finally back to outdoors full time. They also have been battling what I beilive is a N defficiency due to some of the old fan leaves yellowing at the bottom and new growth very light green almost yellow. Also the stems on all the fan leaves have turned red. The reason for this I beilive is because my buddy gave them a feeding of jamaican guano 2 weeks ago which obviously was too soon as the plants aren't into full bloom yet. I leached the soil and have given them 2 feedings of straight water and will give them a dose of mexican guano to replace the N. So my question is I have dark spots on the new growth but not on any fan leaves or older growth. Looks blackish. I am going to try to get good pictures up tomarrow. Thanks a lot for reading this. I greatly appreciate any response in advance.

Well i went and had my run off tested at the local hydro shop. Things are not good. The ph of the run off was like 5.2, and he tells me that my plants are locked up due to too much P (jamaican guano 1-10-0.2) Also the soil they are in was pre mixed with nutes(guanos,blood and bone meal,kelp, etc.) . So. I bought a bottle of flora kleen to help clear things up and get them back healthy befor the full bloom starts. Is there anything else i should be doing? I will be taking care of these full time now as my buddy tryed to kill them. I appreciate any advice.

bottom leaves will dies as the plant grows so dont stress it too much, this is true for all types of plants

Those are organic nutes...the flora cleen ain't gonna help much, it's made fer clearing out excess nute salts, but not the large organic compounds that provide those salts. All that guano, blood & bone meals, kelp...are still gonna be in the soil.

Either, sink 'em in the ground, or repot to slightly bigger pots with additional non-fert'd potting soil. The additional available root zone, without the nutes, will help buffer things out.

Thanks for the advice, after the flora kleen and about 10 gallons of water my run off is back to beeing within reason, new growth is green and appears that the burning has stopped. I'm going to get pictures and post an update ASAP.
