Auto Blue Amnesia Led Grow from MoC

One of the Blue Amnesia got a little bit nute burn. Top leaves started to slowly die. I fed the plant 10 days with only water. I use bottled water with a 7,02 PH and I add a few drops of either lemon juice or vinegar to push the PH further down. Today I fed the plants with molasses. Grape molasses and mullbery molasses are the only ones that I can easly find on my country. I went with the grapes. I guess its effect on soil bacteria won’t change, what do you think? This strain is a 9,5-10 week strain but I think mine will finish by the 9th week. Lets see. Last picture is the stunted Auto Amnesia, I have planted Original Auto Amnesia next to it next to it when it seemed like dying. Anyhow, now both of the girls sharing the pot seem healty to me. Btw, my soil mixture is self made with 2/4 peat, 1/4 perlite and 1/4 of worm compost. I use 19 liters pots and In the bottom of the pot I placed large stones and lots of perlite with less peat to help with the drainage.
