lads this my first grow and i never thought ph was a big thing but my plants started looking weak and purple stems. Anyway flushed and sorted most of the problem. Keep seeing somethin fly by my face so i put up a sticky sheet and caught some of these. Thought i had thripe cause of light marks on leaves. Oh and my first 2 plants got catterpillars somehow but were fine. Anyone know what these sucky b***ards are?
