Novice in coco, needs a little advice..

**Leafy6890** · 18-11-17, 09:47 AM

Hi everyone..

This is my first time that I've grown in coco, been growing in soil for the last 5-6yrs with no problems but since the switch to coco I'm facing this problem, see pics...

Now, I've read quite alot over the last week or so, on the Internet, on here etc but in my mind I'm doing every right and I've gone over and over on things that I'm doing.. Ph, nutrients, light, watering etc.. But just can't for the life of me figure out what I'm doing wrong..im doing something wrong because you only have to look at the plants! Lmao!..here's my list of equipment and nutrients.. Any help would be appreciated.. Thx in advance..

STRAIN: Amnesia Kush (3 weeks veg)
LIGHTING: Mars hydro (x2 600w, 3ft above plants) 18hr on, 6 off.
Pot: 12l Airpots.
Medium: Coco coir. 30% perlite.
Temp: 75c-79c, humidity 52%. Nightime: 20c-22c.
Nutrients: GH floragro, micro and bloom. Using 1.5ml for every 10 litres of each at the moment. Should be alot higher but keeping to this because plants might be nute burnt???) ppm is 300..i use the hard water nute version.
Watering.. I only water when the pot feels light, so every 2 days with nutes. I don't use any calmag because of hard water, plus plants ain't showing no defects in that area.. I always water until a 20% run off is visible.
Ph: 5.8-6.0..(run off)...

Can't think of anything else.. Any help would be greatly appreciated.. Thx..

Looks like your over feeding them and they burning.

Hi joker, thx for reply..

Didn't think I was over feeding them tbh, on cf stick the current reading is 0.6 EC & 300 ppm and the background EC is unmeasurable, meaning it's not picking up anything.. I've just calibrated it and same reading.. Strange.. I've just ordered a blue lab truncheon to be on the safe side now, hopefully that will give 100% accuracy.. What advice would you give on feeding 3 weeks into veg.. EC, PPM, etc, etc.. Below is the feeding schedule I'm using at the moment.. Thx in advance..

Hi chew... Thx for reply..

Really?.. Oh.. You saying every 24hr with nutrients?..bit confused here, thought feeding them everyday would cause even more nute burn?.. Thx

Don't have to feed with every watering man.

How often you feed/water depends on nutrients you are using and if the plants are hungry buggers or finicky. Sounds like you have soft water and not hard if your pens picking up no base water EC. If this is so you will need the calimagic.

Hi Stirl 420

Thanks kbag.. The cf/ex stick that I've got doesn't register anything in plain tap water.. Just in case I've just purchased a blue lab stick to be on the safe side.. However, I did go onto our local board site and just now and I've uploaded a screen shot from water board.. There saying slightly hard.. Oh well, the new stick should be here on Tuesday, so hopefully that will tell me something different, if so, I shall make amendments.. Cheers mate..
