Albertina I [Pineapple Express auto]

Through this week we haven't grown much( the whole week I'm trying to find the reason of the stunted growth. NO luck for now. The most probable reason is lack of nutrients since other requirements are all checked. so on the 11th day I fed her 5ml of 7-14-7 nutrient diluted to 200ppm. I also have balanced the pH to 6.0. There is a chance that stunted growth is due to a too intense lighting. First week it was around 350-400 pphd. When I dimmed the light down(150-200), the plant actively stretched her leaves towards the light . While the whole previous week they were rather neutral or were pointing down. day 13th. Looks like we're back on track! gettin green again!
