Germanoanswered grow question 5 years ago hey my friend , you have couple of problems in the pictures
first with the yellow edges ,it means Light Burn or Light Stress ,cheak your temp in the room , and control your watering water temp. as well (It should always be about 5 degrees cooler than the garden temperature) try use more cool water for the watering ,cheak your light ,they may be too close to the ladies
the second pic, you will be needing CAL-MAG just add 2 mg to watering or you can spray on it , the problem with biobizz is they dont have enough cal-mag in them , you will be needing this always, and it helps the plant with dealing with heat stresss better ,hope this helped u
