Burn or Deficiency

Organoman thanks for the answer. Just to let you know the products are being used kinda like you described already as in a few different products in each feeding. I don't feed them all in one watering.🤣 You're tips are deeply appreciated though! Haven't encountered something similar in the past so I also guessed it's overfeeding but wanted to be sure anyways!

Definitely burning, as evidenced by the super green leaves. After looking at your diary, I'm not surprised, you seem to be feeding nearly every product on the market! Giving them everything under the sun won't result in super plants, just pick 3-5 products, follow the instructions and let them do their job. All the different ingredients in tiny quantities won't actually work as they are designed to, they are designed to work in the quantities/concentrations as listed by the manufacturers, who have spent big dollars formulating their products. Instead of giving a bit of everything, you are better off rotating your nutrients so that one feed they get products A, B and C, then next feed give them products C, D and E, then products F, G and H etc. This way you are "covering your bases" as well as using the nutrients as they are designed to be used and this will provide the most benefit to your plants. At this stage, I would be skipping feeding for 7-10 days to let the plants use up what is already in the substrate, before resuming feeding with a smaller selection of nutrients, instead of a giant mix of the 12 products that you are now doing. Also, 18/6 is better for your plants. Hope this helps, Organoman.

They are really dark geen I think its to much Nitrogen
