mmm, looks like straight up starvation to me, I'm with BII, here,... I see N, P, Mg, S defc.'s for sure,... pH may be an issue, but I lean toward plain lack-of behind these symptoms,...
I hear you on the common dilution advise, and it's sound, BUT you first must consider the concentration of the nutes you use,.. mild nutes need little dilution if any, powerful ones with moderate to large NPK#'s need more proportionately,...
flushing should not have been done, sorry I didn't catch you in time! the last thing you want is to strip the nutes out even more,...and the last pour should contain a weak nute solution as well,.. Flush only as a last resort, when it's clear that the pH is FUBAR and/or nute salts as causing issues,...
..she's savable, but yield and quality are going to suffer,... up your feeds as BII suggested-
... mind HM about high RH during bud, mold is often lurking, trust me,...

Thanks Waira , ill feed tomorrow . At day 36 and loads of pistols shoud I be feeding bloom nutrients and if so maybe 2 ml per litre to start with ? Vertical growth has seemed to stop a few days ago coz ive not had to raise the light anymore .

 

[Waira]

yes on bloom nutes, but slip a little grow in there for the extra N, and adjust overall conc. of nutes accordingly,... ease into the increases!

thanks Waira , I had the feed done earlier before I read your post and I added just the 2 ml per litre of bloom , but I can add an extra ml of grow the next time , then I'm thinking next week of uping the bloom to 3 ml and see how that goes . should I still keep adding the ml of grow ? I just looked at them there a few minutes ago and already I'm seeing signs of improvement . is it ok to keep posting on this thread for a while and ill add pics to show how I'm getting on or should this be in a grow diary ? Thanks again for your help .

sure thing mate, and feed what she can take,.. watch the leaf tips for signs of yellowing,/browning, which is early nute burn,.. no point in pushing too hard at this late stage...

thanks again waira , ive been watering with 2ml bloom and 1 ml grow per litre for the last few days , the girls seem to be coming along alright as in budding but my leaves are still very yellow and with some brown spots , ive got some pics , I'm wondering do I need a cal mag supplement maybe ? should I expect my leaves to come back green again or have I the damage done ?

should I expect my leaves to come back green again or have I the damage done ?

I don't think yellowed leaves are going to "come back." You want the whole plant to come back, and should be most concerned about new growth.

Thanks bill , im feeding every 2 to 3 days with 2ml bloom and 1 ml grow per litre , is there anything else I could do to help my girls along ?

 

[Waira]

right! It's about holding back the worst of it, slowing the fan tapping down,... it's too late for greening-up on the N, and P demand is getting higher,.. 2ml, 1ml,.. haven't you started increasing this yet? Try 3ml, 2ml.. this is still mild, more considering it's not every day inputs,...

Thanks Waira , I've only started them on the bloom nutes after I started this thread which is about a week so I was planning on increasing the bloom today but didn't kno if I should also up the grow to 2ml per litre but I will now, I'm also finding it hard to keep my humidity below 60% unless I open the tent .
