Discoloration from top +burned edges ist normaly a sign for to bright or too Close Lights. But If you moved them perhaps your ph in Growmedium ist off.

what strain iz it ?

Feed her

Boa noite... Maminha opinião a cor roxa vem da genética da planta e também o aproximar do fim do ciclo da floração... A luz poderia estar mais afastadas mas isso também depende da luz que lhe estás a fornecer... Acho que não há grande motivo de preocupação

30cm* type-o

3cm is still very close for most grow lights.. insufficient info to be certain. The last answer i gave 12 days ago still mostly applies. the purple is either genetics, cool temps or a combination of the two working together. under fed and possibly the light to strong at the top. If you've emaintained a normal feeding process the last 2 weeks that would make the 'under fed' part more confident as it continued even after you raised the light a bit. Most lights should be 16-20" away ... more-distributed diodes can be closer, but even the well-spread out bar/strip-style framed lights usually need 16-18" at proper DLI output.
