Hello farmers,This is my first grow. I got this seed from a batch of jungle cake about 3 months back. Strain is jungle cake, about 2 months old. Growing in grow chunks from Gordon. In veg
Tap water @0.6 E.C
Veg+bloom @4grams per gallon,
Life @0.4grams per gallon,
calmag @2.5ml per gallon,
Total E.C 1.8
I thought that was too high of a E.C so I deluded it to 1.6 E.C and PH@ 5.9. Now I think that was still too high. Some leafs have burnt edges,spots some curl up some curl down.
E.C in @1.6 PH@5.9
Any help will be appreciated thanks.

I spray them with push every 5 days or so. If the leafs are clawing does that mean too much nutrients?

@3balls I'll give u the recipe bro
from day 1 of bloom
Base 6g per gal
LIFE .2g per gal
3 ml cal mag per gal
Add SHINE at day 10 ,1g per gal
You should be around 1250 ppms
******
Day 35
BASE 3g per gal
SHINE 2g per gal
LIFE .2g per gal
CAL MAG 3 ml per gal
That's about 800 poms
*******
Day 42
SHINE 1g per gal
*******
Day 49
Water

That's an 8 week schedule.for 10 weekers I extend the 1-34 feed until day 48.
What to expect ? Alot of stretch the 1st 2 weeks,huge roots,and the need for almost daily feedings.The later flower thing would be how explosive that shine is when the base it cut.

Veg is...
BASE 4g per gallon
LIFE .2g per gallon
CAL MAG 2-3 ml per gallon
I've had great results with the Thunderfudge recipe. Keep in mind I'm in RO water so my minerals are stripped and need replenished with calmag. RO water is 0.0 EC and takes +/- 1.33 ml per gal to reach .03EC.

Push is calmg from what remember. Most likely water schedule.

CALI FARMER said:

Thanks a lot @3Balls with the RO water at 0.0 EC, Do you add calmag first to bring RO water to 0.3 EC? Then add 4 grams of base,.2 grams of life correct?What is your EC or ppm after you mix it together? I did almost the same dosage but with tap water @0.6 EC and my EC was 1.8. Maybe with RO my EC Would be at 1.2.

I "structure" the starting water to about .9 by adding 3ml per gal CM then let is mix about 10min. Then add base and Life. This formula is about 3 times the amount of CM as recommended but I don't use Push, I do add a little silica. Your plant doesn't look horrible, given your hard tap water, my suggestion would be following the Thunderfudge recipe but going 1.5ml per gal CM opposed to 3ml and stop using Push.

Keep in mind V&B has a higher EC/PPM than what you might read about as being typical. I wouldn't get too caught up in that. You might take a look at the thread Veg+Bloom Switch, What Should I Expect? and or Hydroponic Research Users Thread

If I had to hazard a guess I'd say the 0.6 coming out of your tap contains a lot of calcium and that's binding up with potassium and throwing your NPK out of whack.

Also, if you feed full strength balanced nutrients with RO you shouldn't need to use Cal mag at all, quality nutrients have enough of both already. I haven't used that stuff in over 15 years.

Dirtbag said:

Sorry I must have misread the first post, you were also adding calmag to that already hard water? I would totally stop doing that for good. Thats almost 100% your problem. Cal mag is really only for use with RO and only if you see a deficiency, but again that should be rare with a good nutrient.

Not sure if its feasible but If I were you I'd think about cutting your water 50/50 with store bought RO or rainwater so you can get more fertilizer in your nute mix. Ideally start with water that's 0.2ec or less. Pretty sure what you're getting is potassium lockout from too much calcium.

Thanks dirtbag, I’ll give that a try next feeding. 0 Calmag. I’m using v+b tap/hard it says for water between 0.3-0.7EC Would it be a problem to go down to 0.2 starting water?

Dirtbag said:

Hmm yeah if your using a hard water specific nute I wouldn't cut it too much or you will offset the balance. It would be nice to know exactly what is in your water though...
