I've been told numerous times on here not to worry about the "blemishes" on my plants as it's "normal" which may be true.. but when they noticibly are getting a lot worse I really do doubt it.. so here are some pics of my plants.. and a screen shot of calcium deficiencies off growweedeasu website.. who agrees with me that it's a calcium deficiency??

Hi Vinney,
Little stoned here but I'll at least bump your thread. You didn't provide much info...and it often isn't as easy as just matching your leaf to a known deficiency.

But that last shot shows clear cut interveinal chlorosis (just a fancy name for fading between the leaf veins. Did it start on lower leaves?

Are you supplementing MG? If not...then add some in. Epsom salts would be good at 1/2 to 1 tsp per gallon with each feeding.

PS If you want more detailed and possibly more accurate info...then provide more info on grow. You know the drill...medium, nutes. lights and all that.

Nope it's not on any lower leaves just the upper leaves that's getting the light..
I'm using coco coir as my medium, I was using biobizz nutes-bio grow and bio bloom, they're under a 400w dual spec, it only seemed to have started when I started adding the bio bloom..it says to start using bio bloom a week after the bio grow.. only been giving them half strength. I've now switched to canna coco nutes with TNC calmag.. started this yesterday and they havnt got any worse this morning..which is good considering they was noticibly getting worse day by day. But one other problem I have with just 1 plant is severe drooping like you can see in this picture.. it's been like it for days now..I've been feeding between every 2-3 days when the pots getting a little lighter.also the ph before watering is at 6.2 and the run off is 6.2 also.

Vinny, try to adjust your pH to 5.8. 6.2 is a little high for a coco grow. Give your TNC calmag a chance to work. Most likely you won't see improvement in the already damaged leaves. Keep an eye on your new growth, which will be your best measuring point. Keep in mind, when plants are re potted, introduced to new nutrients, watering schedule changes, etc., they tend to drink / feed less and look a little less than impressive until they become acclimated to their 'new' environment or food. Sometimes it's just in the span of a day, other times it takes a couple days. Plants, just like humans, appreciate consistency...they too prefer to be creatures of habit. Coco will react and show changes, good or bad, fairly quickly, so give it all a couple days or so, considering your changes. You'll be fine.

Vin,
There's a whole different set of rules for coco. Seems you're using it like soil almost. Lots of coco growers water daily or several times a day even...with no drying. But your runoff is OK. Maybe the nute change will do it.

I've just mixed my next lot of water/nutrients up, adjusted it to 5.8 like you, I've already noticed a difference though since changing nutes and adding calmag, they look more alive even the one that was really droopy is starting stand up better, I noticed for the past week or so the plants would droop really bad like 4 hours before lights go out and don't start looking normal again till the morning.. apart from the really droopy one that has constantly stayed droopy for the past week..tonight they was all standing up looking loads better right until lights out!

Yeah there is that but mainly cause I could see roots coming up through the soil, someone I'm here said to do it and thinking about it..it wouldn't do them too much good being exposed to the light. Plant are definatly getting better now

Glad to hear it Vin. On the root issue...yes light isn't good for roots, but the plants can manage that all by themselves. Roots can emerge from the bottom too. They just get air pruned naturally and it doesn't really hurt the plant.
