1st grow - Stone and CBD

Soooo, week 8 (week 9 if I include the germination/seedling part) First, I had a bit of a problem this last week. Very soon after watering my plants I discovered BL No.3 started to behave a bit strange her leaves started curling and their tips turned brown and within a day they became very dry. So, I figured that one of two things happened,either I overdid my fertilisation or there was a salt buildup in the soil. I am highly doubtful that I overdid the fertiliser since I only add about half of the recommended dose, so I am guessing the salt buildup occurred (I didn't do any flashing from the start). Regardless of the cause, I did a thorough flash used about 20l of water and cleared most of whatever it was out. I also did an extensive measurement and came up with the following table: Data of my watering solution (i.e. what goes in): pH = 6.1; EC = 0.7mS; ppm = 523 Data of my outflow solution (i.e. what gets out), per plant: ML No.1: pH = 6.4; EC = 2.0mS; ppm = 1330 (no problem with this girl) ML No.2: pH = 6.2; EC = 2.8mS; ppm = 2040 (almost no leaf curling, didn't flash it yet) BL No.1: pH = 6.0; EC = 6.5mS; ppm = 4560 (extensive leaf curling, brown tips, crackly), after flashing: pH = 6.0; EC = 1.2; ppm = 862 BL No.2: pH = 5.7; EC = 1.8mS; ppm = 1312 (no problem with this girl) BL No.3: pH = 6.3; EC = 6.5mS; ppm = 4540 (extensive leaf curling, brown tips, crackly), after flashing: pH = 6.3; EC = 1.0; ppm = 741 I hope this get the girls back to their correct path. I would hate to see them die, and it hurts me see them suffer 😥 And now back to my normal reporting, ML No.1 - the tallest girl in town, a model, all skinny and sexy has retained her height, and is staying put at nice 75cm. She is developing lovely buds filling the gaps between bud pops. I think I will end up with a few pop corns but that is OK. No problem there only a bit more work cleaning them. Ha. Otherwise, she looks healthy, is very low maintenance, I feed her with Bio Bloom at the lower recommended dose and she seems OK with that. She might be a bit on a paler side compared to the others but nothing drastic. ML No. 2 - as I wrote could have some salts in her soil that will have to get out. I will do that when I do the next watering. For now she seems OK, no major problems with her leaves, has great green colour, and is developing her buds nicely. The main one seems to be a decent one when this all ends. She is 35cm high. BL No.1 - she had some serious soil issues, and although she didn't show it immediately, she started to curl her leaves and browning their tips. She got a flash treatment yesterday and I hope she recovers well. She is 35cm high, nicely structured, and her buds (although not as full as ML No.2's) are growing nicely. BL No.2 - is also 35cm high. She looks healthy without any salt problems so I didn't treat her to a bath. I only watered her (with fertiliser included) and that was it. Her buds resemble that of her No.1 sister. BL No.3 - was the first one to show problems. She is the weakest of them all (reaching just over 30cm). Her buds look OK though. She got her water flash yesterday, and I hope that cures her ills. So that is it for now. If something develops during the week I will of course let you know, otherwise, I will talk to you next week.
