Blue Gelato 41 Grow - My 3rd

- week 2 of seedling stage, same nutrients as the first week - distilled water is being used for all feedings because EC is 0 - nutrient solution above was mixed and each portion of feeding was diluted with regular distilled water until the desired EC and PH was reached - initial nutrient solution was PH'd to 6.0-6.1 then would usually raise to 6.2-6.3 when diluted - feeding took place twice daily and EC was slowly raised (nutrient solution less diluted) at each feeding by approx EC 50 - EC was built up daily over the week until EC 1000 was reached - so for instance on day 8 seedling was fed 1x @ EC 450 then later @ EC 500 - the same through the days up until day 12-13 when the nutrient solution wasn't diluted at all and EC was at full strength for the solution above (approx EC 1000) - the seedling started showing signs of a Calcium deficiency (twisted leaves/discolouration) - a CalMag solution was made @ EC 800 and PH 6.2, placed in a spray bottle and gently misted onto the leaves - the deficiency seemed to clear up by day 14 or so *** A personal observation I witnessed was that the humidity was too low and the seedling seemed to be slowing in growth. This was because I removed the humidity dome due to the fact that the seedling was stretching too much and I wanted to get the light a few inches away. The humidity went do to between 50-60%. After a few days when the seedling stopped stretching I placed the humidity dome back and got the light down almost touching the top of it and the seedling EXPLODED in growth over the last several days of this week. It was a huge improvement and I learned that humidity is important to seedlings.
