Hi can someone or a few of you guys n girls on here try n help me out ... been struggling for a while with this defficiency and i cant figure it out ...

its affecting plants in veg and flower
plants are all in coco , ph of feed/water is 5.9 - 6.0 , coco run off is 5.7- 6.0.
using hesi coco nutes , with some extra pk13/14 and canna boost for flowering plants.
iv tried adding epsom salts to feeds but so far this has done nothing , iv also tried playing with the PH and this has also done nothing ...
temps are around 70 - 72 Fahrenheit in darkness and 77 - 80 with lights on ...

Plants are growing strong but still all showing same symptoms .... heres some pics of the leaves.

I'm not a 100% sure, but to me it looks like cal/mag deficiency. What is Ur water source? If u are useing distilled or RO water u have To treat it with a cal/mag in the water cause it is stripped of everything

If u said its not the mag/cal, then water is next bet. Seems like ur doing everything right, but some where its not, do u test the ppm/ec b4 u use it?

Not true....I havn't let my tap water sit in over 5 months, and havn't seen any mal effects, my hydro plant might get effected a little bit, but the soil plants don't care at all.

He meant do you calibrate your meter before use?

Yep, the recommended dose for soil grows is half that of hydro .7-.9 ec. IDK what the threshold is for coco but there's always a limit, and if your water already has high ppms, that leaves less room for nutrients.

EVERY area's water is diffrent, some can use water straight from tap, and others better not or ur plant is fucked. The ONLY water I use is distilled. I am fixing to bugy th RO water system for the house though
