AfterCheese & Crystal M.E.T.H.

Scheme: VEG9-FLO7/8 12/12 - FLO7/8-FLO? 11/13 Watt: 70 Height AFS: 19cm or 7,5inch Height Crystal M.E.T.H.: 20cm or 7,9inch Watering them with app. 2l each, every fourth day. I use rainwater (PH ~6) without additives most of the time. Equisetum arvense was applied on day 25 after 12/12, last sunday. BioBizz CalMag was applied (1ml on 2.5l) on day 29 after 12/12, yesterday. Crystal M.E.T.H. looks pretty wild. AFS shows the same symptoms, but not so severe. Edit1: One leaf of AFS shows sign of nutrient burn. Few sporadic burned tips. It started this way with Crystal M.E.T.H.. They are both in the exact same substrate. Exact the same treatment their whole life so far. Crystal M.E.T.H. was very picky at the beginning of her life. Little mutant girl. AFS grows withouth any noticeable anomalies. I have reduced the wattage to 70W, and decreased circulating air for about 50%. I suspect PH-fluctuation due cold temps at night. Lets see how they develop the next week. My second theory is that the seramis i unfortunately put into the substrate, has lead to build up of salt. Ive read expanded clay accumulates them. 😖 Until then. Lets Grow! AFS: Started from two male Afghan/Spliff Seeds (Afghani Kush IBL). They pollinated a fem. Terminator/LSA (=AF). Out from these (AF) i planted two of the freshly developed seeds. One from them was a healthy male which had a very pleasant citrous scent. The other plant was a female. You can take a look at her in my Diary "Winter Withdrawal". This male pollinated a fem. Sweet Cheese/Sweet Seeds. They become AFS. This plant is the first i grow from these seeds.
