plants with issues NEEDING HELP PLEASE

[kar]

Hey there, these photos show the probs. That's a Arjans Haze 3. Started inside w 600 watt. started looking unwell- aphids. i'd moved 2 others out 3 weeks earlier and they'd improved so did same with the last two. Never had indoor or purchased seeds before. Also I've never had plants with these issues either, though I am in Australia and it's my 1st winter grow. I used a nicotine wash on the Haze3 and I only use an organic fert. Can you please advise me anyone? I am out of my depth here. Thanks heaps. and sorry those pics are shitty

Yeah, you can't tell but the brown leaves aren't crisp or dry at all. Kinda mushy. Our place has stacks of dew and rain too right now. P'raps i should bring to dry out? It started going pale a month ago. Outside it started getting brighter, but then even tiny bud leaves browned off. Could the nicotine wash hurt if some dripped in the soil? aS it did.
