Hi good people of RIU
need some help identifying a problem that started about 4-5 days ago.
Growing Barney's Farm LSD, in soil (a local grow shop recipe, should be similar to BioBizz Light-Mix). end of week 4 of veg, 5 plants are in 10L AirPots. feeding them in every watering (every ~5 days): all BioBizz: 2ml/l BioGrow, 2ml/l BioHeaven and 2ml/l Alg-A-Mic.
all 5 plants are under the exact same conditions, but 2 of them started showing signs of what looks to me like either N or Mg deficiency. bottom fan leaves are almost bleached, with purple marks on the stems. and it also appears like the new growth on these 2 plants is much lighter in color. so i cant quite understand what's going on... am i underfeeding them (or overfeeding, god forbid?). if this is Mg deficiency, is Alg-A-Mic enough, or do i need to add some CalMag, or Epsom Salt (not sure i can get CalMag where i live)
Water: PH: 6.8 PPM: 800
Run off water: PH: 6.7 PPM 430
attaching some pics...
PLEASE HELP!
thanks
