Hey guys, happy new year.. i been off for the past two days and came in to this with my think different girls, i think i might used cal-mag too much is that what i`m looking at here? these signs appear just two days after my last cal-mag application with the feeding, PH coming out is good actually i keep my feedings around 1.0-1.4EC (0.4 TAPWATER)

and im using additives aswell by need cal/mag + rhizotonic + cannazym

I add 4ml/l bio bloom and i get 0.8EC than i use canna boost and pk 13/14 or atami bloombastic untill i reach 1.0-1.4 ( i often raise and low the ec in these ranges )

Well you know more than me cuz I dont own any meters no more. Not even liquid ph meter. Only accurate 8 soil probe and ph perfect nutes. I also dont feed by the charts. I start with a little and up it every 4 or5 days till my tips get lil burnt then I leave it there.thats just how I do it and dont recommend anyone else tryin. Im also not advanced enough to give legit advice but if my plants looked like that only on tops and have red lines on main stem, and not blue or purple strain. Id up my phos. Just my 2cents

It looks like a calcium deficiency. How much are you giving them and how often? Also, how old are they?

That's not enough to treat a deficiency. They recommend 5-8 ml per 4 liters for normal use, so for 6 liters you should be giving at least 10-12 ml. Since you are showing a deficiency I would suggest upping it to 12 for normal feeds. I would give them at least two feedings at 16 ml, then drop back to 10-12 and give it with every feeding, not just twice a week. At 51 days your right at the time when we usually see cal/mag issues.
