7 plants at preflower showed nutrient burn or deficincy and was caused by high ph . Gave them a good watering with 6.0 ph and the runoff from 7 droped to 6.4 . But also runoff watered had 300-400 ppm wich i think is low . Shouldi give them a bit nutrients now to absorb or wait until water dries ?I just think that now that i fixed ph with such a low ppm at this stage they will get worse due to lack of nutrients in soil . Also one of them that was the worst of them with pottadium deficiency due to ph high strectched like crazy gaining nearly 10 cm in less than a week and now is at its limit distance from lamp and its in flower about two weeks now and i am afraid it will burn top main bud. Cani do something for that because i cant raise the lamp higher (ts 1000 with 30 cm minimum distance from plant during flower and i am already at 31 distance and for sure it will grow more than 1 cm)
