answered grow question 5y ago
If it is late bloom then it is relatively normal for leaves to start yellowing. You could put in some cal mag if you wanted to but if you are nearing harvest or flushing then I wouldn't worry man., just leave it and continue as normal.

Rust-colored margins and dots. I would like to go back to fertilizing but I am afraid that it is an excess of potassium
Outdoor in the vegetative phase, southern climate. Soil is Biobizz light mix. So far I have only fertilized 2 times with the tripack ph perfect Advanced Nutrients. These rust-colored burns are present on almost all older leaves. Enlighten me please π

Brown dying leaves
What is going on with my leaves? Even the sugar leaves are starting to die. Sprayed with optic foliar switch to prevent male flowers popping up a few weeks ago so could be that.

Growth looks like it's stopped, is it time to flush?
2 of my plants look like they've stopped growing now and the calcium deficiency looks worse and worse.. should I just flush then with water for a couple of week and be done with them? The late bloomer looks like it's got ages still, definitely not what I'd hoped for being autos

Sugar leaves affected- 6th week of flowering
If you have a look at the 7.5lt one, the sugar leaves affected by a deficiency, I was thinking of CAL... Considering I'm pretty close to the harvest time, shall I simply flush and switch to plain water to be on the safe side?

Maintaining the soil pH
I give pH'ed water, never more than 800ppm and I still always end up with lockouts. I used to not give water untill runoff but now I do. What to do after testing the runoff? It's currently at 6.0 even after a flush with 7.2. Ask many questions I need to know what I'm doing wrong.

Calmag and Nutes next watering
So I checked runoff on watering today and PPM is between 100-150 on each plant. Should I give more nutes on next watering including calmag? Was thinking of going to 1ml per l now?

Discoloration on leaves. Why?
I was looking at a closeup view of an overhead pic I took yesterday and noticed some slight tan/bron color along the sides of the 2 bigger leaves. I'm wondering why. Nutrient burn? Sulphur deficiency? Something else? Any thoughts?

Continuing calmag deficiency
What I think is a calmag deficiency started about 10 days ago. At first I thought it was too low PH (6.0 - 6.1), so I corrected that, but no luck. Then I started adding biobizz calmag, still no luck. It seems that the deficiencies are picking up speed again. Any ideas appreciated

Ongoing pH issues
Watered at 6.5 pH and runoff was at 5.5. I am going to start watering at a higher pH today and continue measuring runoff. Should I stop feeding at this time? I have been feeding 1/2 dosage of Fox farms trio with every watering last 2 weeks. Is there likely soil build up to flush?

Will she be ok
Should I worry or should she be ok, watered with plain pH 6 water 81ppm runoff 221ppm no further burn but will this slow her down and as I'm sure it was bloom nute that caused the burn should I even bother with p/k in next few weeks if she can't handle bloom and buddy?
