Lucas formula, nitrogen defiency

[superbolan]

With coco the pots should never get lighter. I would be either feeding or watering at least every other day till you have at least a bit of run off, Remember even with the coco saturated there is a great deal of air.

Dgr: I think i just will go for full strength. I'll check them when i get home and depending on how they look I'll go with what you suggested. I'll let you know bro.

Suprbolan: point taken. thanks

can me anyone say how many ml i use
from the new GHE Stuff FloraDuo Bloom like the lucas formula?

many thx

what are you running?

coco / hydro ?


check out the nutrient section for somemore info, just type in the search flora duo, and floraduo.. I've posted some ratios that are close. also have alot more that I think are suited to hydro..

I also believe this nutrient is more suited to hydro then coco, and they need to up the Mg / Ca ratios.. who wants to keep adding cal/mag or epsoms...

when you let the pots get light before watering the nutrients that have not been taken up by the plant, concentrate, reforming bonds that were broken when they were in solution. Sometimes they recombine into things like salt and worse. When you water with nute solution next time, you increase the nute level even more and even more concentration will occur next time it dries too much, This will lower the pH in your coco and cause mag and cal deficiencies. the claw is more likely a calcium def than a N glut. Esp since it happens on top leaves and N overload only makes things darker green.
Your nutes are fine, just a little pH problem. Keep it 5.8 - 6.0 and it will work out. Though some strains might need a bit more than the rest of your plants..

I've heard different things, but what you're saying makes sense though. I'll water more frequently from now on, like eod. My last grow went well but since then two things have been changed, the nutes and the fact that this is the first time I'm growing in the summer.

However, fed them yesterday full strength. some tip burn but not that bad. Will do another feed tonight. any idea how long time it will take for em to green up?

foliar feeding is my preferred way of cranking up N while bringing overall nutrient levels up. it'd be your call as to what to use. personally, i grow lucas (0-8-16) and just foliar feed a 3/4 strength solution. it greens up quickly.

The Lucas formula is for Flora Micro and Bloom. I dont think you can use different nutrients and expect to use the same formula.

If you're feeding 6/9 you will need to supplement with either epsom salt or cal-mag+...

I'm feeding GH 10/15 (micro/bloom) in flower right now with no additives... no burn, no deficiencies whatsoever , plants are in perfect health... 2.0ec throughout flower
Ph 6.0-6.2 in straight pro-mix
Straight ph'ed water every 4th watering

In coco I'd keep the ph at 5.8-6.0

For veg I use floranova grow... 1.2-1.4 ec for the first couple weeks
around week 3 of veg I add start using the micro at 5ml/gallon.
1.6 ec for the rest of veg

I love GH... cheap, easy and works great.

I use 1k's and grow bigger plants which are 2ft tall when they go into flower...smaller plants or plants under less intense light don't eat as much.

i am using this same formula, 10/15 M/B, i was using the lucas 8/16 but noticed some yellowing and light colored leaves in my bubba kush, so i upped it to this formula with some cal-mag and my leaves returned to such a dark healthy green it was great.

yea this is why i try to hit my ladies with a nice nitrogen spray right before i flip them or after i flip them.......i used to underestimate foliar feeding, i see results real quick after a spray and now my ladies are nice dark green in flower when instead they would get bright green after about 4 weeks...


i use GH 2 part too but i supplement in soil with other things.....just started my first coco run with GH but adding calmag, humic acid, and sensizyme on the advice of several very good growers (cup winners)....so far at week 2 flower they look good....


i also dont measure by ML...i just add at 5/10 ratio until my PPMs hit the right mark, at week 4 id guess between 800-1000 but maybe im wrong...usually its under 5/10 per gallon possibly 2.5 and 5 instead.....i start light and bump them up weekly till i see burn...

Yeah I use headz recipe, sorry for the mix up. I got a slight tip burn the last time i fed and that was not even at full strength. I think I'll play by the book but I'll use 75% of full strength next feed. as for the coco, i don't let it dry out completely i just water when the pot feels light. Theyre yellowing from bottom tothe top so its def lack of n. Any suggestions?

Yeah...I'm running Headz recipe as well. For watering...I just use Blu-mats in my Coco. Get my reservoir above my plants. Add drip clean at about 0.3ml per gallon and 2 ml magi/cal per gallon as well.

As for the Micro/bloom...2.5 and 4 ml/gal respectively.

Ph to 5.8. Though I have to say I'm new with the recipe and the gravity drippers. I need to tweak it myself as I'm seeing some signs of slight N deficiency and slight Cal/Mag deficiency.

i was going to say something, but then HAZY said it first. he is spot on, listen to that man. dont listen to people telling you to add this or that, to change your feed dosage, etc. continue feeding the 6/9 at 5.8 to 6.0 and it will work itself out. you cannot over water coco, btw, coco is not soil. h3ad will tell you the same thing.

something else to consider...when going into flower, at a certain point youre going to WANT to cut back the nitrogen--too much green leaf at the end of harvest translates to green tasting weed--this is not what we want.

best of luck.
