I got a few leaf issues in late flower

The first one here is from my Alaskan Purple Auto. She's 13 wks old. 8 weeks of flower so far. She's got 50/50 pistil color change but nugs are still swelling. I'm noticing strange leaf discoloration.

Online it seems close to either nute burn or potassium deficiency. Just watered her with the Alaskan Fish line of 5-1-1 and 0-10-10 Morbloom. I did 5ml the Nitrogen one and 5ml of the PK one. I also added 2ml Calmag per gallon.
Ppm was about 800 each feed once a week with ph water in between.

Also some leaf tips are breaking off. This just started around 2 weeks ago when i reduced the rH from 60 to 50%.

The humidity im keeping at 40 to 50% and day Temps are running 79 to 81F. Night tenps are 70F




I'm experiencing the broken yellowing leaves on 2 of my other plants as well.
I make sure the soil is drenched then let it dry for 3 or 4 days testing with a moisture meter and by picking the pots up. 7 gal easy to tell cause when they wet they're heavy as shit.

Some more leaf pics now these Purple Kush are ending week 10 of flower and are 18 weeks old.




The Dr Earth grow of PKush isn't showing as much on the top areas of dry brittle yellowing leaves. But the lower fan leaves always seem to be droopy and this leaf below came off her and it looks like Potassium deficiency.

What do you all think is going on?
Thanks

You're fine man. Don't trip. Looks real good.

Thanks. Yeah my first grow ever last September I lowered the RH to 35% when it was in peak flower and it nuked my 2 autos leaves made them yellow dry and also I had real bad calcium deficiency cause I forgot to put 1c dolomite lime in the fox farm soil. So I made my own organic soil this time and no brown spots in mid flower like the first grow.

I tried DWC on one this time and I got the hang of it so I'm going all DWC next grow.

I ordered seeds during the 420 sale buy 1 get 1 and 20% off and 10% off for new customer coupon. So I scored 24 seeds for 80 bucks. Northern Lights, Granddaddy Purple X Dosidos, Blue Dream and Gelato.

I'm interested in growing a Sativa and Blue Dream is supposed to not make you paranoid cause the Super Skunk I grew in September is dank and strong and I took 2 hits and it set me into an anxiety attack for 40min then it chilled. Issue is I quit smoking for 13 yrs and just started back up cause I though people were lacing the weed but I didn't know then that there's 2 different kinds and 1 kind is speed weed Sativas. So i tend to grow indicas only.

pretty sure it is the result of letting your soil get too dry. I have to water flowering plants in 7 gallons everyday and my RH is twice as high as yours.

The Blue Dream I've tried isn't racy at all. I think you'll like it.
Keep your watering regular like waterproof mentioned.
Your plants are too far along to have any substantial problems before they're done.

Thats interesting. I know you cant overwater fabric pots cause it drains out in the drain pan. I believe youre right as they are 3 on the moisture meter after 3 days. About 5-6 in deep then it slowly goes to moist then wet at the bottom. Ill try every 2 days and see if theres a difference. I usually water 1 gal every 3 days. I think 7 gal can take 1.5 gal so yeah im not watering enough then.

Cause my DWC Kush plant she drinks 1 gal every day in flower so far. In veg it was like 1/2 gal in mid to late veg. I was like why she drinks so much but the soil ones still wet the day after watering. Maybe its harder for roots to absorb water from dirt than just floating in oxygenated water all day.

Thanks for the info.

Your plants are no bigger than mine and I grow in 4gal/16L pots that I only need to water every 3rd or 4th day but I let them get a little too dry I think.

Your plants are getting pretty close to the end and the damage is so minimal I think it's just normal senescence kicking in as the plant is finishing up. I've had strains that yellow so bad you'd think they were starving but they were early finishers and that's just the way they rolled. Better than toxic salts buildup frying your plants.

I'm using ProMix HP with lots of organics like manures in it so barely feeding anything and they look like they are getting nute burn.

I've done mostly DWC since '01 but about 3 years ago started going more organic. Been a bit of a rough ride for me but I'm liking it and always grow a lot more than I can use so don't need huge yields. more into CBD, autos and breeding fem seeds. Just harvested some fem auto beans last night. Spraying STS on 3 plants tonight for their 3rd spray so hope to see balls pretty soon.
