i upped the floods to every 4 hours, floods for 5min and drains in 5min. my ph is at 5.8 now, i added lucas 5-10 lucas formula on friday which put the ppm at 760 and topped the res monday afternoon (with r.o water only) which put the ppm at 700. i think I'm definitely going to try lowering the ph though because when i put the notes in the res the ph came to like 5.4,5.5 but i added ph up to bring it to 5.8

Ya! Keep us posted on the outcome. Sounds like a good plan.

Yes, not enough. The medium is pH rising, causing CA Def, if you flood more often, and maybe lower pH a Lil more, the medium will get reset to proper pH more frequently.
I agree.
Ph 5.5 for hydro for the win. 5.9 works wonders in coir
Flood more often!
Problems will disappear
Im not a hydro guy i do coco but know that 5.5 is solid in hydro and keep them wet just like anything else hydro its a fine line between perfect and not

alright I'm lowering the ph now, hopefully it works out because this is just getting ridiculous now, these plants are 2 months old and look like what other peoples 2 week old plants look like

not white, like a tan/whiteish color but none of the fine white hairs you see on really healthy roots, theres no smell though and i can only see a few roots at the bottom of the pot on the bigger ak48 plant
In pot ph
In pot ph
Almost allways pot ph is off.
test last drips from pot tilted at 45 degs at 1 hr and 2 hr after flood.
Main causes are hard water the carbonates build up in the hydroton
Ive had to ph rez to 4.5 in a very hard water area high calcium carbonate.
Another cause is crap hydroton high ph from the maker i found 1 idiot company selling ph 9.0 not a fuking clue .
I realised that i needed RO water ) no carbonates ect
And to ph the hydroton prior to use ,you can still get probs depending on the the make ive seen one type take a whole crop with rez at 4.5 ph and pot run off at 5.5 swinging to 6.5 in 2 hours after flood,
Then when reused after drying and flushing with ro water and 1 initial ph soak in plastic dustbins
it was perfect ,250ltr rez ph 5.8 pot run off at 2 hrs drained last drips tested ph 6.0

Yeah even in coco I switched my Cal mag from a carbonate to a nitrate version. No more deposits of calcium.
