Critical AUTO shooting for 2Kg !lets see

PPM Week 2 = 520 150calMag - 150 NPK - 180 tap water PH: 5.8 ------ As all my grow seeds stretch too much. I decided to keep the plant at 5000 - 7000 Lux max in order to not burn. Previous grow I slightly burn the top. Adding some water every 3 days with10% runoff. ------ Day 12, lowering the light. Dimm to 400W each with a 400W bulbs ( i read that if you DIMM a 600W light you loose PAR ) better using the correct bulb. Lumens 10.000-12.000 Plants need support, will add wood sticks. ------
