It means a slight excess of p and k, nothing much tow worry about, just don't up the flower nutes quite yet and make sure you use just plain water every now n then🌱👍

What is this deficiency?
They started off with some brown spots and progressed. Is this phosphorus? I have been feeding with .5-1ml of dyna grow bloom and 2ml of cal mag per gallon watering at about 6.3-4 ph. But i recalibrated my ph pen and did one water since.

Polkadot plant
Just spotted two yellow/orange spots on Vera, my young GelAuto. The bigger one is visible in the pic, the second is smaller and on another leaf. What is she trying to tell me?

Too Much Light?
Top looks yellowish, more so IRL than in the pic and the new growth is kinda taco-ing. Just under 24" from the light, 78F and using Photone the DLI was at ~30. I don't really trust that app but if it's even sorta accurate, 30 might be high with no CO2? says their charts anyways.

Leaf tips yellowing. Overwatering? Or nute burn?
I recently flushed my soil with water that was PH 7 (my soil was a bit too acidic). My question is: are the yellow tips and browning due to the overwatering from the flush? As well as stripping the soil of its calcium? Thinking of giving them 3-4 days before watering with calmag

Losing vigor and yellowing
Sorry I don’t have a diary for this grow. I did collect some runoff on one of my girls so hopefully this can help for giving assistance. This is only my 3rd grow and the first 2 went very well but this one isn’t, all plants have lost vigor, are growing slowly and are yellowing.

New leaves have yellow and/or curled tips (-> nutrient burn?), and many leaves have their edges curled up (-> root problem?). The pot that I'm using is fairly small and only has a small hole for drainage. Can this develop into a serious problem?

Brown spots on lower leaves - ph fluctuations?
I have discovered some brown spots on the lower leaves. I suspect it might be down to ph fluctuations - first time growing DWC so probably my bad! Does anyone agree? I should also add - I did a nutrient change a few days ago and for the first time added calmag & silicon

Yellow Burned Bud Leaves. Purple Calyxes. Red Stigmas. Stunted?
As u go from top of canopy to bottom, the leaves get darker green and less burn. Lamp is at top of 3ft tent, 10 inch above canopy. Feed is at 1.3EC/6.1ph. Runoff EC climbs, then I FloraKleen flush about once a week. So is it just light burn? What you see? Is she stunted? Thx.

Yellow spots on leaves
Are the yellowing spots signs of Leaf Septoria? I'm assuming it's more of a nutrients issue but have never experienced LS and wanted to get some second opinions.

Purple leaves getting worse!?
So I started getting light purple/yellowing last week, after my last grow question, I landed on potassium deficiency. I gave a healthy dose (2 tbsp in a half gallon of spring water) of Fox farms big bloom (0-.05-.07), within the last 48 hrs and the purple looks worse? Any ideas?

Plant issues... How long to harvest?
Could someone please look at my (only) diary and give me an estimate on when harvest might be? I have microscope pictures up . I think I see cloudy trichomes with the possibility of a few amber. Maybe ready now? Not sure but hope to harvest before plant gets much worse. Thanks!

Excess or Defiancy?
Some leaves from the top of my biggest plant, Frisian Dew, turn yellow and brown. The others don't show this behavior. The plant is in week 22 and still needs approx. 4-6 weeks until harvest. The plant pot is fully rooted up to the surface.
