Day 28 of Flower(lsd)! Necrotic Leaves, Should They Stay or Go? Pics!

What up people? Day 28 of flower(lsd&blue mystic). Overall I think they look killa IMHO! Having some sort of prob with the LSD and her bottom fan leaves. Is it nut burn or a deficiency? The top of the LSD looks killa and I have not seen any necrotic leaves up top. Only down at the base on the bigger fan leaves. I am In coco and using canna nutes. Fed them last night. Mixed 8L of ro water. Added 1tbs. Of Epsom salt. Ec was 1.04 after that. I then added 4ml of rhizotonic, coco a&b 20ml each, and 7ml of Atami Bloombastic. Ph'd to 5.8 and the final ec was 2.45. I use the canna calculator after mixing in the Epsom salt. Canna had the ec calculated at 2.3. For final mix. But that was with cannazyme and cannaboost. I didn't add the cannazyme this feed and don't use the cannaboost. Also have co2 in the mix controlled by an atmospheric controller so i know heat and rh are not the problem. Not noticing anything bad up top. Buds are forming and looking great! Nice and green up there also! Not sure what the prob down below is. Also I flushed with 6gl of ro water with a mild mix of nutes the last gallons. That was last week and yes the necrotic leaves were around before the flush. Still got about a month or so till I say Timberrrrrrrrrr! Anyone see any major problems? Nute burn? Deficiency? Should I trim these eye sores off or let them do their thing? Will it stress her too much to remove the crusty ass leaves? Thanks for any feedback! +rep fo sho!

The yelllowing of the bottom leaves is completely normal... but in the last pic it looks like your starting to get a mag def, see how the right side leaves are starting to spot?

Hey thanks for taking the time bro! I do see what your talking about in the last pic. I think that is the lighting and trichomes appearing. I have looked her over. Pretty good and did not see spots up top on those newer leaves. Gotta wait another 10 1/2 hrs till lights on to double check that. Thanks I'll look into it fo sho but I do believe it's lighting and trichomes! Good looking out! +rep bro!

good luck dude and those ladies look mighty nice....I just ordered some LSD beans, haven't grown them out yet tho. Keep us posted

looks like mag deficency .....

my 1st instinct tells me P deficient. dont remove any more leaves! there was till plenty of resource left on those leaves for the plant/buds to draw from! rather cut off the necrotic areas if u must.

also i would use a calmag type product over epsom, as the uptake of the nutrients is quicker & more efficient.

Yup, cant hurt to supplement even if that's not the problem.... So I have a question? Say there is ample amounts of calcium but lacking magnesium, would using calmag possibly interfere with other things because of too much calcium?

yes toxic levels could inhibit the uptake of K, mag, manganese, & iron. But I highly doubt using a calmag supplement properly would cause those high levels.

Hey thanks a lot for the feedback! I'm gonna make a run a get some sort of cal mag supplement. Thanks for the kind words about the LSD plant. She's looking great and I'm glad I topped her. First attempt at topping. I also topped my Blue Mystic which is a beast. She's not as photogenic as the LSD. Thanks again for the feedback!

awesome job of course on the overall plant, she's a beaut 4 sure!
