Mistery Auto #1 (caseeds) NORTHERN SPAIN

Everything seems to go smoothly. Plants are growing healthy but I suspect they are doing it slower than I'd wish. But given the climate and time of the year, I can't complain. It is a pity but it rained almost all week, just having intermittent clear moments and a whole day of direct sunlight. As I said the previous weeks, I don't want to overwater the plants, so I just sprayed some foliar with pH 6 on day 15. Soil is still wet when I put my finger in. As it didn't dry up enough as days went by, I started to worry because I hadn't even watered once. Neither fertilized-in theory it was enough with a good quality soil but...- Then I decided to pour in some root stimulator and a little bit of Nitrogen fertilizer to stimulate vegetative growth. *How to make root stimulator: put a cup of dry lentils and four cups of water inside a container. Keep away from any light for 8 hours, and then strain the lentils to keep them in the container again-covered from light-. Save the water. After a day, put the water in and strain again. Repeat for 3/4 days until all of the lentils have germinated and have a root around 1 cm long. Then pour the water in again, add some more and finallly triturate and strain again, having as a result what you can see in the picture I added. Use the liquid in a 1/10 ratio with the water. *How to make potato fertilizer (N): cut up six medium potatoes and put in a pot with 1L of water. Cook at medium heat for half an hour. The resultant water is ready to use -after pH correction- for one plant. I knew my plants didn't need water: soil wasn't dry and leaves were stiff. And given that they are small and autoflowering (need less food than normal), I just added 0.5 L of the potato 'tea' (I made it half concentration) with the corresponding root stimulator (I used a quarter of the recipe's ingredients) for each plant. Can't tell TDS yet, but I bought an electronic tester -for pH too- that is going to be delivered soon. This same day (number 18) I added more soil, up to the cotyledons. Which means I'll measure a cm less at the end of the week. In three days I can say that results were amazing. Plants are growing way faster. I consider that they are big enough to start bearing the cold at night, so I stop using the greenhouses as I did. Also, little green hairs start to come out of the internodes where I'd expect flowers to grow, and it makes me worry. What if they are already starting to flower! It is very soon yet!
