Well, my grow started out rocky, and now when I think I've gotten it sorta figured out and my plants start growing real nice, i start seeing the bottom leaves start to yellow. What should i do to fix/stop and prevent this?

That is a sign of nitrogen deficiency. Check the levels of NPK in your soil and adjust your fertilizer accordingly. It's not too late to keep your plant healthy!
 
Well, the soil that they're in now 22-11-18, and i thought I was overdoing it on the nitrogen, I'm just confused on how much nitrogen I should add, without raising the acidity of the soil too much.
 
This chart really helped me when I first started so it may also give you some help. It is also unfortunate because often times deficiencies show very similar symptoms. With the soil you have it in, you would think there would not be a problem. You should check the pH of your soil because soil with a pH that is too high or too low can lock up nutrients in the form undissolved salts and other compounds which are actually toxic to your plants (and will keep your plants from being able to take up the nutrients it needs). Marijuana grows best in a pH of 6.5. Do you have a meter? You can also get NPK and PH tester kits from Home Depot for about $4.

Hope this helps!View attachment 1749209
 
I'm gonna leave right now and go buy a meter..lol, That chart is scary...from the looks of it, i have a nitrogen, and possibly a zinc deficiency?
 
It could also be straight up burn if you are in nuted soil, how long have they been in that soil?
 
Okay, so, I got a PH Meter from Lowes, and did the test twice. I wasn't sure if I needed to test with the soil wet, or dry, so I did both. The dry test showed off the chart (10+) PH levels, and the wet test balanced out between 6 and 6.5. If that's the case, I'm guessing it is a Nitrogen deficiency? Can anyone recommend a good (preferably inexpensive) nitrogen supplement for my babies?

cheapest is probably shultz liquid at any store for 5$ but i prefer an organic fish emulsion for 10$ at lowes
 
What about a Fox Farm fertilizer/supplement? I'm looking at Fox Farm's Grow Big right now, would that be a good option to fix a nitrogen defic?
