Sativa martian mean green lower yellow leaves

[beavergoods]

I currently have a martian mean green that is having a problem with yellowing on the lower fan leaves.

I'm using promix hp and the ph is at 6.4 out.

I've been using the same formula for all my plants but this is the only one showing this deficiency. I'm really confused.

Please help.

It looks like u may have a couple problems. To me from what i can see in the pis it looks like over feeding it looks like u may have the claw from to much N. Being that far in flower id stop the rizo i dont know much about the other nutes ur usein. R u using lucas formula? It may be a overdose of nutes lockin out. Also if u r using a high k solition it will cause a problem with the mag so u will have to up the mag most of tye time when u use bud boosters but if it was me i would back off the nutes alil u got some really dary green leaves for being thay far in flower u should start to let the N go def as u get closer to harvest. What week of flower r u?

I think you may be onto something with the extra mag i gave them a feeding of cal mag tho and it didnt help. its not too much N as I've been PK boosting i started removing the n a few weeks ago and last 2 nute feedings they got a high pk dose. I did push the monster bloom a little bit far... maybe thats it not too sure at this time.

They way tuey look it is kinda hard to tell in the pics but if i was to guess id say high salinity causeing lockout oreven looks like nutes may have spalshed on a couple leaves. That maybe it since its only one plant but it wouldnt hurt to drop ec a tad bit i did see a slight burn on a couple leaf tips. What is ur ppm in runoff.

Ill have to measure it later. All my other girls are gorgeous just this one havin problems and I'm assuming it has something to due with the fact she's a sativa.

R they all different strains? Why would it be cause shes a sativa unless the pthers r different strains. Im just curios but how far into flower r u? Btw i love that strain. It makes me happy :dance:
