First time growing/Need help in late flower
Over the last 9 days my plant has gone from happy and healthy to sugar leaves pointing straight up near the top of plant and drying and curling up on the lower levels. Is this from too much light or did I over feed late in flower? First grow/ no diary. Can I save or do I chop?

The last few days I had 3 plants start not looking so hot. The 3 pictures are the 3 plants when I got home today. I haven't really encountered deficiencies, if it's even that. I'm watering at 5.8 and last I checked the runoff a 2 days ago it was 6.8. Any ideas?

Ph Issue
I want a Ph of 6.5, but when I check the runoff Ph I get 5.9 or 6.0. I just Ph'd the feed water at 7.0 to get around 6.5 where I want, but the runoff stays around 6.0. Any idea what's causing the Ph not to go up to where I want it at 6.5?

Why leaves brown? (urgent)
Some leaves turn brown as in the photo. Leaves in the middle turn brown first, then bottom leaves. Now I try making larger lamp-to-plant distance and feeding less nutrients, but no good sign appears. Other conditions are stated in my diary. Why do you think it is?

Can this delay flowering of an auto?
What deficiency is this please? I suspect phosphorus deficiency and as such have reduced the PH from 6.4 back down to 5.8 It is not spreading and appeared spontaniously and at once a few days ago. Growth has been slow for almost 2 weeks and flowering has refused to initiate.

Brown patches on leaves, thought it was calcium deficiency symptoms.
Having problems with brown patches, (see last 3 pics week 10), a quick google and I went with adding more CalMag but it's got worse the further into flowering I go, the farthest behind plant has least, furthest ahead is worst, any ideas?, many thanks in advance :)
