I checked ppfd it was in range but I will check again. I have been using this feed schedule but only Big Bloom, Tiger Bloom, Grow Big. Also open sesame, beasty blooms, cha ching. Have been using 1 tsp/gal cal mag. Feeding 2 times par week. No sledgehammer flush.Not sure of much other than a pic and a mention of a broad range of nutes.
If you are in soil and using FF 2 part and on this schedule let me know how long ago you did the flush with SledgHammer. We see this a lot with that nute choice, dunno why it's in the schedule.

If your grow is not that let us know all the stuff medium, lights with ppfd ( led got that) feed method amendments all the stuff.
as low as 5.5phView attachment 2466584
That leaf is either burnt by nutrients or the PH. You might be having excess and deficiencies at the same time in which case Im sure its the PH. In any case wait for more people to chime in because I might be wrong.
When you said you might have gone a little low with the PH, how low is that?
Like regularly or one time? If it was a mistake, did this start to happen after or before?as low as 5.5ph
Yes, I was gonna comment on that too. If they tell you to flush 2 times before the final flush, must be because they know you get salt accumulations. He is not using all the supplements but still, good point.So no sledge hammer. Multiple deficiencies and lowering pH.
Immo qualify this with I grow Organic and not chemical ferts. I do know I have seen this a lot with 2 major times being a pattern in that nute line. You covered one with amending with cal-mag. The second one is a buildup that fox farms Knows happens and at week 4 and 8 they recommend the flush be done to reduce the possibility of this happening.
Not sure if that's your big issue but I seen the pattern for a while.
Isnt fox farm organic? Sure they put stuff like phosphoric acid to facilitate the intake of nutrients but even fox farms soil comes with microorganisms by default and their liquids are designed to feed them. Also google confirmed my suspicion that sledgehammer is not only flushing agent but also a feeding agent for the microorganisms that come with the soil or that you might be supplementing.Ok you have refered to a biological microbial activity that takes place in an Organic grow, you have instant available chemical ferts in those bottles. After the flush and dry back the nutes you put in a ready available. They will not need conversion.
If you dont use a flushing agent like epsom salts or sledgehammer youre not gonna get rid of the salts. You should flush at 6,5 ph yes and after flushing you should reintroduce some nutrients.Wow lots of good info, THANKS! I did go 5.8 on ph several times, maybe the main issue. Should I flush with 6.5 ph water? I don't plan to get sledgehammer.
Only water when first 2'' are dryHow often have you been watering? Ocean Forest holds onto water pretty hard. When I see speedbumps and pronounced venules on the fan leaves, I wonder about over-watering.
