Without a picture or two of the issue, it is very hard to provide any suggestions.
However, burned tips is usually a sign of feeding too much or too often, or both, and after looking at your diary, you sure are feeding a lot of different nutrients. A baby plant needs baby feeding!
Also, 24/0 is really stressful for plants and 18/6 is the optimum schedule.
Plants NEED sleep to finish their photosynthesis cycle and have a correctly functioning metabolism.
A plant with an incorrectly functioning metabolism will never grow to its best potential.
24/0 could only be recommended by people who don't understand photosynthesis or understand how plants function either.
The myth that it is ok to grow a plant for weeks/months without sleep needs to be removed from history!
Everything on planet earth lives by a circadian rhythm, without one things go very wrong.
Fortunately, it is never too late to go to 18/6!
Your plants will love you once you give them the sleep that they NEED.
Hope this helps, Organoman.
