Im not totally sure tbh mate but they look underfed a bit but then again have brown dead leaf tips which usually is an opposite to underfeeding which then looks like lockout of somesort in other pictures maybe caused by overfeeding. But at 600ppm your hardly overdoing it and tbh im edging towards underfeeding simply because of all shit your putting in alongside A&B which all effect ppm so in that case then theirs hardly gonna be any AnB in your fert mix so maybe N def what with Hammerhead having P&K alongside AnB well theirs probably enough of those. It certainly doesn`t look like calcium or magnesium def and why you using epsom salts if using cal/mag epson salts its for magnesium def and pure magnesium sulphate and cal/mag is contains calcium and magnesium which covers both those, basically don`t use both those together and tbh i wouldn`t be using any running a low ppm unless you suffer with cal/mag problems and if you do then try a little higher ppm after flipping for 3 or 4 weeks when plants are hungry as fook gobbling it down, if plants can take it just so they dont start to look hungry, you could probably drop back down after 4 weeks
Myself i`d be dropping everything except AnB cus they looking light in N and run a ppm at 600 and they should come round in a week or two if it is what i think it is snd what ive said and when they start to green up you could maybe drop AnB a little and bring ppm back up with hammerhead.
Maybe check a bit of run off just to be sure salts aren`t building, take a bit from first lot coming outa pot bottoms will give a more true reading.
Small rockwiool cubes on their own may become soaked as well so can cause root problems which in turn may reflect on to your plant, i used to run a 50/50 mix with clayballs till i disacovered coco and overnight plants were bigger fuckers yielding more bud, hint hint lol
Cheers bud, I put some of the extra cal mag and Epsom in cus my water comes out at 120ppm an I thought I may have had a mag deficiency. I defoliated a few days ago and saw mottling on a few fan leafs up top, so thought I'd go low on cal mag and epsom to chuck a bit of sulfur in aswell.
I did flush them out saturday and ran a weak bloom, amino and epsom through it ( about 340ppm including base ppm ) then topped up with bloom to about 500ppm and a smidge of green sensation as it's all I've got for a pk boost at the moment. I've just bumped them up to 700ppm with some bloom nutes.
I never run more than 750ppm tops as I think my water is pretty good, but I also think this Ionic Bloom ( soft water ) is pretty light on cal, mag and other traces.
They're waking up shortly so I'll go check. The mid and lower growth is a nice deep green aswell and they're starting to purple.
I think the pollen I chucked was a cookies n cream x dosidos onto a platinum kush breath, but the terps are screaming old school bubble gum.
