1st grow - Stone and CBD

SO, week 9 In the past few days I did a thorough measurement of all my plants pH, EC, and ppm levels. You may know previous week's log and saw that a few of my plants showed stress. I came up to a conclusion, that it was the salt build-up in my soil causing the problems. For that reason I did a fresh water flush on the most of my plants and reached acceptable levels of the water run-out. Most of my plants which showed problems are getting back to their normal state however, one plant, BL No.2 still showed stress signs. Eauderay made a comment that it might be due to light stress pointing out that the stress signs are concentrated to the top part of the plant. Although that is not completely true (there are some leaves yellowing/browning throughout the plant) I raised the lamp another 15 cm (from the highest plant) just to be on the safe side. Worryingly though, I have discovered a very low pH levels in its run-off water (pH=5.5). As is known that might lock out some essential nutrients so I used pH-up yesterday and did a double flush, using about 20 l of fresh water. Into went: 20l of water, pH=8.9, EC=0.3 (ppm=264), and out came: pH=5.7, EC=0.9 (ppm=654). Although pH was still low I decided to stop the flushing for two days, and then (if the reading still shows too low values) do it again. The readings for the rest of my babies were: In: pH=6.5, EC=0.7, ppm=506 Out: BL1 - pH=6.6, EC=1.2, ppm=882; BL2 - is described above; BL3 - pH=6.1, EC=1.9; ppm=1337; ML2 - pH=6.5, EC=2.4, ppm=1686; ML1 - pH=6.4, EC=1.5, ppm=1123 So, considering the numbers I still have some problems with BL3, and both MLs however neither is showing any serious problems so for now I will let them be. Hopefully with some slight adjustments I hope it will sort out slowly. Update I did some close check of my buds and happy news, there are some milky trichomes visible. I didn't do any magnified pics yet, but I will do them for my next week's diary. Yay, coming close now. Also, there are some colouring of my pistils.
