Any Help Would B Greate

[tinderthumbs]

think its K def but I have changed nothing still the same soil and nute as before and never had plants in veg go funny thinking its bc they mother plant was lacking when I took the cuts so they where all ready on the edge of it does seem to be more mid/top of the plant not sure where to go from here even some of them the tops are tacoing and turning in to a black mush never seen that before

soil is promix 3g planters some 5g

That don't look like no k def to me. How fast did this come on? Looks almost like leaf septoria to me. Can you take a photo of the tops? That's usually cause by root issues or fusarium. Is she or the mother outside or greenhouse? What do you feed exactly. This degree of deficiency would be rare and slow to come on in veg.

Yeah wow that would be the latest k deficiency in veg to my eyes. Definitely looks like very late stage k def. I've never seen one go far enough to actually cause rot in new growth. When I'm looking at something ill go and grab my books and read and this definitely syncs up with late late k deficiency.

Your description definitely almost mimics this book here ill shoot it for you lol. This is your ed rosenthals growers handbook ask ed edition. None of these books are perfect but this one is consistently more correct than the other 4 i also have to compare it against. In 9 years I've never seen a k def that bad in veg and I've done it in purpose but never past 4 weeks.

Sorry i edit so much but check my last post here. Should have made a new. It's late here lol.

 

[tinderthumbs]

yep looks the like info in my book as well

don't know what to do really not sure if I should flush more or dump nute on them

 

[xenon730]

Well it could be caused by lockout. Did you flush and then feed? Whatkind of ppm are they getting?

Yeah i checked that book also. It's far more descriptive about it. I was gonna shoot that one for you too about the rot lol. I use my own test notes also but they never went necrotic in the same way as yours so it looked alien at first.

 

[tinderthumbs]

I don't know about ppm never had a reader kicking my self now
Im thinking a lock out as well I flushed then splash of nute on each plant

its for sure a good read

I Can tell you your ppm if you use popular products And list the amounts for me. What are you feeding and are you using promix hp?

 

[tinderthumbs]

this is what Im using

 

[xenon730]

this is what Im using

I haven't used earth juice very much but i have tons of experience with retail promix. That is promix hp with their organic fertilizer added. It depletes usually in about a month to 6 weeks of rapid growth and usually as stretch is ending when flowering. Youre basically growing in soilless now, peat and perlite. I would start feeding half strength grow regularly with a half strength shot of meta k just to get things rolling. You could just feed full strength bloom actually because the pro mix is full of n. The fertilizer they put in it is 20 8 8 so.

so no flush feed half strength and a booster of mera k

what should the ph be with a basically soilless mix? does that lean on the lower side like coco?

Yupp. 5.8-6.2. You could feed the bloom formula cause there's probably some n still in there. The fertilizer they add to it is 20 8 8. Do you use catalyst in veg? It's a kelp humic+ iirc and could be used once or twice a week. I would wait to use it but if you want to add a little more food.

well that might be it right there I was ph at 7 then thought was to high so dropped it to 6.5
I do not use the cata in veg
