Red Mimosa XL Auto indoor/outdoor

((I'm starting write in Day 57, 6° May.)) In 3th of April I put the seed directly in the jiffy at 19-23° and high humidity. She's born the 10/4. For this cultivation I'll use: LIGHT I'm in Sicily and summer is coming. I'll use both indoor and outdoor way. I have a grow box of 80x80cm and a poor lamp of 150w declared but not efficient PPFD. Given the exposure of my house, there is light on my balcony for about 7h. When the temp and the sunlight allow I put her on my balcony and then again in the box for a total of about 16-18h of light per day during all the phases. Now there is 8-17° outdoor and the plant is at her starting so the first two weeks I let her all day in growbox until the temp outdoor is ok. WATER & NUTRIENTS I always check the ph of water/solutions i give her, always between 6.25-6.7. For Nutrients I'll use for the first time minerals: the "top grow box" of Plagron with Terra Grow, Terra Bloom, Power Roots, Purezyme and Green Sensation. I'll give the according to the quantities adviced by Plagron Guide in base of the week of growing, 80-90% of the advised quantity. I have an EC-meter but I will not use it to check in & out ec-value of the solution, if I see problem on the plant I'll start check (now it's day 57 and all went fine). I gave the nutrients almost each time i gave water, 3-4 times during the growing phase I gave just water with ph ok. SOIL Light soil of Terra brand I added mycorrize
