Trying to Catch Problem Early - Help!!

[sun_blazer]

My 2 white widow plants each seem to have a different problem developing. I wanted to nip it in the bud before I make it worse! Please help!

Both are in week 3 of flowering. Last week I slowly switched over from Grow Big (N) to Tiger Bloom(P, K). I have also been feeding Big Bloom which is pretty weak.

Plant #1 ph has been about 6.5 - 7 while plant #2 has been 5.8 - 6.3.

They are in different soil mixes: plant #1 is 60% organic soil/40% FF Ocean Forest while plant #2 is 100% FF Ocean Forest.

Today, I fed #1 some Grow Big and Beastie Bloomz, and #2 just Beastie Bloomz.


Plant #1 looks to be a N deficiency: <--- This first 3 pics on the left
- leaves turning lighter green
- some stems purple color
- tips turning yellow

Plant #2 looks to be a Potassium deficiency: <--- The last 3 pics on the right
- leaves are a dark green
- tips turning a color but it is very hard to tell


Can someone please confirm and give advice on feeding?

Maybe a SLIGGGGHT nute burn on the first pic, but overall they look fine. I know it's hard not to want to baby every little thing...

Don't worry about the big fan leaves during flowering...

They look fine to me too...
