Name my Deficiency. . . .

[SensiMilla024]

PPM was at 1100 with ph of 5.9

The yellowing started occuring on the bottom fan leaves and has slowly

crept upwards.

I initially took out half of my 10gal rez......added 5 gals tap(at 40PPM)
Also added was 150ml of hydroguard and 10ml of superthrive.

I initially thought it was N def but didn't make to much sense being I"m

3-4 weeks flowering. I'm now leading towards mag def.

notice the sugar leafs clawing and curling under

its N def, but its ok, a plant this late into flowering should be alright since it doesnt look too severe, and dont worry about the sugar leaf curling because i have had that happen as a phenotypical trait as opposed to an over fert problem, if it was overfert all the leaves would be in "claw" mode.

rkrone....thanks man for your input. So, I guess I'll just continue on with

my normal routine.......weird that one plant in a 10 gal rez at 1100PPM would

encounter N def.......especially running GH lucas.........

I think It could've been too much P K blocking out the N???

looks pretty normal to me whilst in flower,dont look so bad ...

It's just a little too early to be suckin out nutes from fan leaves.


I wonder if me pollenating a branch had anything to do with more N usage??

 

[SensiMilla024]

So the General consensus is N deficient???

Looks like N to me too. Have you grown this strain before? Some strains' leaves start to yellow during flowering. Your buds look great.

 

[SensiMilla024]

it's the first time with this strain.

It's the Church by GHS

I don't think the curling is due to strain. I'm seeing this happen to 4 different strains in the same NFT table at week 2 of flower. This is not happening to the same strains in soil.

I'm also running lucas at 0-6-12 per gal and 8ml of CM+. pH never leaves 5.6-5.7. I was seeing signs of both calcium and mag defs before going to 8ml from 5ml of CM+.

My first guess is that this is a result of overfeeding. I noticed this happened to some of the smaller plants first when I upped ppm to 975 to keep the hungry strains happy.
