Third week of flower Leaf issues

I agree with the above. Most likely something that was done a week or two ago and just seeing the results now. This helped me out

What do you guys think is causing this ?
My best bet now is I think I nute burned her

When’s the last time you calibrated your ph pen?

I stick it in the 7.0 liquid before every time to make sure it’s calibrated

Look above I have given that information

P deficiency IMO.

Problem with that is I read it starts on bottom leaves it seems to only be on top of plant

Well it certainly could be nute burn based on my earlier statement regarding light levels vs salt levels with autoflowers.

Ok guys I am giving it a flush today to try get this sorted properly. I have given it 4 gallons of sledgehammer 8 gallons of ph water and then 2 gallons of 1/2 feed and calmag does that sound good ? @Starless @MrPeat @Myfriendis410 @Watt-Sun

Fox Farms stated that if you flush with 1 gallon SH you need to then flush with 2 gallons. Then you are supposed to let the soil dry out completely.

I did a flush with 1/2 gallon SH and then added 1 gallon water.

Ok guys here is the update.
Flushed till 6.4 PH 276 ppm
Then I fed beastie blooms, big blooms and calmag at 7.0Ph 440ppm
My runoff from that final step was 6.5 PH and 363PpM

What are your guys thoughts ?
Thanks so much again
@Myfriendis410 @Starless @MrPeat @Watt-Sun


I think your runoff TDS is low: 650 to 750 ppm for autos and 900 to 1,000 in photoperiod. Plant could also stand to have a good defoliation done.

Yeah I know I didn’t want to over feed after the flush just wanted some nutrients back in the soil will give a good feeding after the soil dries

Weird question,but the fan leaves that are in the inner canopy covered by other leaves . Are they showing the same kind of damage as the ones directly exposed to the lights ?

It’s only the top of the plant showing damage under canopy isn’t

Your issues mimics something I had going on a few grows ago. I never figured it out. Tried everything. It happened on 2 straight grows. I switched my nutrient line from advanced nutrients to jacks and never saw this issue again. Wish I had a solution for you. I didn’t defoliate because the under growth was the only thing that didn’t fry and carried the plant to harvest

Yeah looks very similar! I think it’s some sort of immobile nutrient issue but I really have no idea lol I’m not going to be defoling any more for that exact reason. I am really hoping that flush and getting my ph to 6.5 will do wonders but I really have no idea haha

She’s gunna get ugly but as long as there’s green left you should be able to get her to harvest

I think she is looking a lot better fed her again for the first time since the flush.

What do you guys think?
