Hi all, new to the forum and got a few questions.
first time to shine and got a little beauty on the go she's coming to and end now week 7 of flower after 3 month veg, she's in coco in 11ltr Airport and been fed bottled nutrients ( coco grow A+B/coco bloom A+B + MagCal+ ) from the start with me adding a bloom booster at the start of week 4 until the end of week 6, are her leaves suffering from burn ? Or just age ? and could anybody recommend harvest time ? Any other advice welcome 🙏

Hi Jakey, good start.
Are the CFLs your only lights or is there something else in there? I can't see CFLs burning the leaves like that unless they're almost touching.
Do you have a very strong non-oscillating fan? I've seen leaves under too strong a direct fan die like that. Could there have been a PH problem in veg? From the looks of things it's affecting the mid plant growth.
Have you been doing plain Ph'd waterings as well as nutes?

A closer pic of the trics would be more definitive but I'd say you've got at least 3 more weeks left. The trichomes in pic #3 still look clear to me, and in pic 4 you can see that you still have some white upright pistils. Once the trichomes go "plasticky" white then your harvest window is open and you start flushing your plant

I'd be tempted to snip off all the damaged leaves and water to run-off with plain Ph'd water (check the Ph of your runoff too). This will be a bit of reset for your plant and any damage you see thereafter might be easier to localize and identify the cause of.

It doesn't look like typical flowering leaf die off to me, that tends to show as yellowing droppy leaves on the lowest level of the plant.
 
Looking like the plant is using and wanting more N...what is your % off nutes you are supplying her...might want to up the dose..a bit. Make sure ph is at 6 with coco
 
I ran your plants symptoms through the plant doctor and closest pic was a potassium deficiency..........your symptoms look more severe though.....this is just a suggestion dude....don't discount others answers.....experience goes a looooong way in this game😁😁 happy growing😁😁
 
FOr sure potassium. Could even be a root problem impeding intake or ph out of range. Just by seeing all the thing you feed your plants I can assure you, you have a built up problem or at least EC way too high. If I were you I would flush and measure EC in and out
 
Thanks for the info Beach_Town, the growth through Veg was great and I water every other feed, will try a good flushing now iv stopped the added booster
 
The nutes are the plant magic coco range and Iv been giving her 75% of bottle recommendation every other feed between watering. Could the problem just be PH ?
 
Most definetly the deficiency is a symptom of a bigger issue. You are already feeding them so that's not it. Check the basics. Like green said ph is real important. Check your roots. Check the ppm or EC to know if you have a buildup of salts in the medium (you gotta research some more about this) even too much of certain nutrients can stop the intake of potassium. Your goal right now is to figure out the root of your problem
 
Not measured on this one, tried to see how she would do, after all this advice I will be measuring from the start of the next
 
Yes I have a 4 way CFL splitter under a Euro hood, 3 x 45W 1x 125W, they were 3x 6400k for veg and 3x 2700k for flower. Also got PC fans one blowing under canopy one blowing up and another blowing out

Fixed the problem ! It was light burn from the big 125W CFL being so close for so long, think I should of raised the lights a bit earlier, all buds now swelling nicely in final weeks :)
