Is this a Mg def?

LMFAO . . . . it's day 35 man . . . . . GH invented Lucas Formula?? Was it not Lucas?

My Strawberry Cough wouldn't stand a chance with an old idea like that, many of the new monster strains won't, it's evolution, our plants are getting more demanding through genetic mixing etc.

I suggest we all need to start to re-think old ideas like "the lucas . . whatever" for some of these newer strains available today, a different breed of plant today than when old Lucas was "the thing"!!

Wakey wakey, get an up to date feeding schedule for these up to date hybrids!!! imho

He wasn't stating that GH invented the Lucas Formula - he was pointing out that on the GH feeding schedule, week 9 and 10 were the same as the Lucas Formula. If you weren't such an asshole you may have been able to comprehend and understand his statement. The objective of the Lucas Formula is to provide more magnesium to the plant. Something they need in abundance during flowering. The weed may be more potent today than it was 15 years ago but it is still cannabis and their nutrient needs and plant physiology remains the same. Different people have different methods that work for them - just because it isn't your way is no reason to be rude and narrow-minded.

I'm not actually sure how to really work out NPK values but does this look right anyone???

thanks Mick. couldn't have said it better.
love assholes who think that feed charts on websites are the holy grail. it's not even cannabis specific.it's a general guide to anything grown hydroponically. and my response to the OP was that it is a Mg deficiency and it's a result of only using 1 part bloom and not 2 like Lucarse (he's pretty witty, huh?). Lucas is 1-2-2 btw.

Awwwwwwww man, where was I actually rude? I was only playing . . . . . . you'll very rarely see me swear either, only in jest, asshole??? was there any need?? "Fuck Lucas Formula . . . . lol " . . .do you see that as rude an aggressive, the wink and the LoL???? wtf????

I'm very aware of Lucas . . . and, just coz my way is very different to yours, I don't think there's really any reason to be hostile, is there . . . . . . ????

He has a Mg deficiency . . . .If you DO try the last two weeks of GH's schedule now OP, you'll screw it, guaranteed, it's too early for that, the proper combination of Flora Hard is designed for situations just like this.

GenHydro is NASA's choice for nutrition in space, why, coz it can be so perfectly tailored by adjusting ratios, . . . . .OP please, follow GenHydro's schedule and don't try to adjust it yourself by skipping entire bottles out of a three part . . . . .


and @MickFoster, come on man, I wasn't being rude, I was saying Fuck Lucas formula, like mates at a bar would chatting, that is how it should be here . .. .just busting banter! So . . . less of yr lip sonny . . . . (do note the wink, before you go all poooofey again!!!) lol

I hope its just an Mg...would 70%RH cause this? My veg area doesn't have a dehumidifier as I hear you can go higher in veg up to 70% even. But this is the worst my plants have looked in a while. And I STILL have red petioles...Which is what I was trying to get rid of by switching to 1-1-1.

It's only happening in my veg area. My flowering plants are fine thats the only reason I ask. The flowering plants are still on Heavy 16.

My understanding on NPK values you take the number multiply it by the parts you're using it in relation to other parts.

So if you did GBM all at a 1:1:1 you'd add up all the numbers. 7-6-11

LOL bet you've spent a $$$$'s on your Cannabis specific nutrients . . . .lmfao . . . . woooahhh ha hah aa aaaaaaa

yep, spent tons of money on GH micro and bloom. cannabis specific nutes.

The red potioles? Likme Red or more purple? If red? On top ? If purple? All over??

70% RH is pretty sound for young vegging imho . . . though you wouldn't want much more.

What sort of max and min temps are you getting???

No wait what ?????

It was a GenHydro Flora Chart . . . . . .wooooah ha ha ha haaaaaaaaaaaa

Cannabis specific or not bro???

Man I hate these forums...Cannot even get an honest discussion going without peoples feelings getting hurt and names being thrown around. Sides being drawn and taken.

I've been using 3ml/gal Micro and Bloom. The feed is dropping from 350ppm to 300ppm since I changed the res so i'll up the nutrients in the same 1:1 and throw in some more calmag and target close to 450-500ppm. I was just worried I was overfeeding. I have a plant week 6 in flower right now if I set ppm to 500 the remaining water come res change will be 1000ppm. Perhaps because its 85F in there and its drinking more water trying to stay hydrated?? Putting an AC in this week, these 90F days are killing the room.

Hurt . . .. lol . . .. me???? pffffff

Yeah ok at 85/90 and an obvious bit of Mg n praps Ca missing, the plants are finding it hard to deal with the slightly high temps, causing the ruffling . . . . lowering temps is the best way, hurry up AC, lol a Ca/Mg folia feed will help some . . . .

Yeah generally, I reckon you can afford a few more ppms dude

Temps don't fluctuate much since i'm running 24/7 lights. Its about 75-80F at canopy.

This is what I mean by red petioles...I took the group picture that was in the original post and numbered them for a better reference, they are all the same strain. The back right(unnumbered is a clone off a different strain. Seems unaffected and is at 550ppm(what I set everything to originally)



THESE ARE ALL SHOTS I JUST TOOK 10 MINUTES AGO:

#1 - Just starting to get that leaf margin cupping, not nearly as bad as #3


#2 - Looks healthiest, but this lower leaf has some weird mottled yellow between veins.


#3 - The worst off, more leaves have done that margin roll up.


#4 - Margins on new growth starting to yellow. New growth looks similar to #1.

Sorry for the confusion. I started talking about my flower room. No foliage issues. Plants are just going thru a ton of water 1gal a day and as a result my leftover nutrients doubles on the last day. Im battling this currently by feeding 400ppm.

The veg is 75-80F

Thanks...Look up the #

sorry to get your thread sideways OP. yes it is Mg defic. yes you could fix it without CalMg by using 2 parts Bloom and not one. Your NPK would be 1-2-2, not the 1-1-1 you are shooting for.

and @Semper Fi , i created a thread just for you in Advanced Marijuana Growing. Love to hear you explain the Lucarse formula. You're up first...wink

awwwwwww now some one is ruffled up enough to start a thread just for me??? pffffffffffffff, relax man, take a long draw on your bowl bro . . . .slow down, don't let me get to yah . . . it's all good . . . . . . .

You'll need some Ca min the mix too, the gnarly looking growing head (#1 especially), it's a good sign of the start of not enough Ca imho . . . ..

Thanks for the input guys

Going to add more nutes now. I cannot be burning at this low.

**EDIT**

All the plants besides for clone are at 450ppm and set pH to 5.9 as my pH has been dropping(possibly because too low feed). So Mg is available then it'll drop to 5.8 and then both Mg and Ca will be available.

Since I gave them 3ml/gal micro and bloom I did 2ml/gal extra of bloom and 2ml/gal to go with the 1ml/gal I already added originally of magical...So im 3ml/gal micro 5ml/gal bloom and 3ml/gal magical(has N in it so i'm sure my ratio is around 1-1-1 still.

3:5 micro to bloom ratio gives me 15-0-3 + 0-25-20 + 6-0-0 for magical = 21-25-23
