I'm thinking either Calcium def or early Potassium def. Any insight?

I think you have a little potassium overload, but you should be fine... 4 weeks into flower it's kind of normal to get some yellowing and burned tips... you need the extra K to get the BIG BUDS! If it was a deficiency you wouldn't see the scorching on the tips like that.

yep, looks like a slight over nute. you could flush.

Couple of questions. They have been in the same pots and soil since they started? and did you give them TB and GB at the same time for the first three weeks of flower? BC

 

[TheJuggalo87]

B.C. No, they have not been in the same pots, but they have been in the same Soil mixture.. Yes I gave them GB and TB in the same feeding..Never seemed to hurt before. I figured they would use the N for the stretch.

Got side-tracked, sorry!`

Got side-tracked, sorry!`

Howdy man, I thinks these other fellers are right, those are classic signs of nute burn. It prolly would be a good idea to flush em, and then at the very end, run some Big Bloom through the soil, say like a couple of tbls per gal. BB is nothing more than a mild tea that will help keep yer soil and *roots in good shape...... Although you would probably be fine jus not feeding for awhile, yer PH is at 6.5 which tells us there's not much salt build up, if there was, the PH would be lower and you would have to flush. So it's yer call on what ya wanna do there...

When a plant is in veg it doesn't use -near- the food it will in flower, so go easy. There's nothing wrong with using N a couple week into flower through the stretch, but we're jus looking for a healthy green color, if it's already there, not much is needed then.

About the time they set bud, 2-3 weeks in flower, they start going through a -lot- more water all of a sudden, there looking to up take more food at that point. They continue to do this untill they are about done, and suddenly they slow way back down again. The time to lean in to the TB and BB is in this window. Not all strains can stand the same amount, so watch for signs of too much, now that ya know what it looks like fersure. Workin with the same strain(s) fera while will help you dail all this in.

I also wanted to mention the rate that yuv been using the BB at, is low. I know it get's expensive, but you won't burn anything with it. More BB less TB might be somethin ya wanna think about. If you use a lot of TB I think it's wise to leave it out and once in a while and give em a big blast of BB to help condition the soil and keep the roots healthy....

Anyhoo, I hope some of this has helped ya. If ya have any questions hollar. Good luck! BC

Hey btw, my son is a Hatchet Head! lol... He jus went and saw em in Milwaukee, Wis this last weekend. Came home soaked in Orange Faygo! lol
