Is this a potassium deficiency ?
ShareBearstarted grow question 4 years ago
I believe that this plant is suffering a potassium deficiency, but can I get another opinion?
-The leaves aren't curling up so I don't think it's light burn.
-I have been really light with the nutrients out of fear of nute burn, but have been increasing them recently.

Hey friend, I think you have nutrients lock out(some yellowish colour leaves)and nitrogen toxicity(some clawing leaves).Normally plants don’t use much nitrogen in the flowering stage. Improper pH level and excess use of vegetative nutrient can cause nutrients lock out and toxicity. For me, I would flush with pHed water which is three times of your pot size and wait for her respond.Then slowly start with low strength blooming nutes.Happy growing... ✌️

I had the same problem and eventually noticed that it was only happening on one side of my plant. Turned out to be the side that the fan was on. It was too direct. I moved the fan up, problem solved. The tips never changed back, but the spread stopped.

Give ya my best here lets see...
At that PH target any downward variance, and these pens can vary .3 easy, you are in trouble with Phos and CA which can cause problems at the top of the plant looking like light burn in ways. CA and Phos have a REAL close relationship in flower.
If she were mine I would up the PH to center of the range, 6.5, so if it varies a little things are still cool.
In particular important on soil where you wont add anything to change the PH for days.
Good luck

Hey. Next watering check your runoff ph and ec and find out whats out of whack. When going into flower, nutes should be lowered. Start low increase as neccessary. Live by less is best. A little higher in mid flower, then back off again for late flower.. it almost looks like a zinc deficiency starting, but the culprit is probably cuz your ph is out of whack somewhere. Cheers friend

Low PH runoff, dealing with deficiency due to low soil PH. Added lime and PH went from 5.4 to 5.0 after watering. How to raise it safely and quickly?I have been dealing with a nutrient deficiency so added nutrients.It looked ok but then got a bit worse and I took some runoff readings which were 5.4 and then 5.0 the next week after adding lime to raise soil PH. How can I best raise the soil Ph being that I added lime already.

Whats going on?So.. 6th week into it. My leaves have various brown spots and yellowing spots in no particular spot. There is some browning on leaf edges. Also tips are up. I am thinking cal mag and to much heat. But not sure. I lifted light up and so far nothing. Also started adding cal mag .

Not sure about deficiency, thought was Calcium or Magnesium but not sure anymore.The nutrient deficiency is back so I gave it another double dose of CalMag to see if that can stop it in its tracks but I am not positive if that is the specific problem. Added micronutrients mix as well to see if maybe that helps. Any suggestions would be appreciated.

Add CalMag or Manganese? Still slightly discolored and veiny leaves on week 6Calcium or Manganese deficiency? Last week had what I thought was early calcium deficiency. Gave it a dose of CalMag but now not sure if it’s still Calcium or possibly Manganese.
I do mean manganese but I realize it could be a CalMag or Manganese deficiency as well.

Possible pH issue.(15th photo) I've a few leaves which are not looking the best. Does this look like a pH problem or does anybody have other info? I have dropped a bit of lemon into this plant which is the only one with this issue which has not touched the other 2 plants under the same regime. Tx
