1st Crop

Your giving the correct nutes so I'm going say your ph is out of range. In soil feeds ph should be between 6-6.8 Next feed check your ph going in and coming out in the run off.

Hello! It seems your plant is in need for more Magnesium. Give her some extra dose if possible thru foliar spraying so that it can absorb as soon as possible. I hope it helps.

Firstly, go to 18/6 ASAP! Plants NEED a dark period every 24 hours to complete their photosynthesic cycle and have a correctly functioning metabolism. The myth that it is ok to grow cannabis for weeks/months without "sleep" needs to be erased from history ASAP! Only someone who does not understand plant biology or how photosynthesis works would recommend 24/0 as a grow method! Your plants seem to be generally starving, but the weirdness could also be a result of growing at 24/0. I would be changing the light cycle and also giving 2 feeds of just grow nutrients for a nitrogen boost, before resuming with the bloom nutrients. A dose or two of cal/mag may also help as would a dose or two of soluble trace elements, as there seems to be an iron deficiency too. Soluble trace elements can be found in any garden centre and can not harm your plants, but will help correct any minor deficienies and boost plant health too. Hope this helps, Organoman.
