Ok thanks for all your help. I hope you're right
I'll use a few drops of superthrive as well and see if that helps any. Just so i understand what i did wrong i need to ask a few more questions.
Ok so i was feeding them with a ph that was too high, meaning that the plant was unable to absorb the nutrients, is that right?
What exactly causes the nute burn?
With the feeding schedule i was provided with my nutes, i use 1/4 strength for weeks 1&2 and 1/2 strength for weeks 2&3, but often by week 3 they require watering twice in a week, should i then give them 1/2 strength solution twice in a week? Or is it better to give them the nutes at the beginning of the week and if they get thirsty top up with water?
Hope that makes sense
