Calcium deficiency?
GreenCosmos
started grow question 3y ago
Saw this little brown/yellow parts today. She is in BioBizz LightMix Soil and gets 0.3ml/L BioBizz CalMag 3x per week. pH is above 6.5 . Today I gave her 1ml/L CalMag. Was this the right choice? Is this a calcium deficiency?

This is calcium deficiency and likely due to ph getting too high. Likely need to increase feed amounts

I'm not sure if it's calcium because it forms from the edges and makes lines, which seems more like PHFluctuations

Is this really a potassium defiency? Any suggestions how to deal with it?
Hey Guys, need your help please. It's FD 28 and the leaves of my three White Widows show some signs of a nutrient deficiency (at least my assumption).I'm growing in living soil w/o any additional fertilizer and watering with a 7:3 mix of osmose/tap water and 0,5 ml/l CalMag.

More rusty spots
See this now on more and more leaves. Only upper fan leaves that get good light exposure seem to be affected from this and also the clawing. Have backed off the nutes completely for now and will add ground egg shells to the water in the hope its a Ca deficiency.

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.

Calcium deficiency, cal-mag now in hand, water now, or wait for normal scheduled water? Last water yesterday.
Plants are suffering from an early stage of calcium deficiency, received a bottle of cal-mag today. Watered last night cause I didn't want to wait any longer. Should I wait for my next water (2 more days) or give a single dose of Cal-mag now, to get some calcium to the plant?

Deficiency?? Excess? Neither?
Grown this strain before and had the same issue.. not sure if its a CalMag deficiency entirely. pH has remained at 6.0-6.5 or so in soil and didnt show signs until recently, seemed to have worsened after just two days of only CalMag and Ro water so I bumped up the bloom nutes.

Are those nutrient defficiencies? Which ones?
A plant had interveinal chlorosis on new leaves and then proceeded to show brown patches between veins on middle leaves. Another has coppery brown spots on leaf edges on the middle of the plant. Both were rootbound in living soil (peat/perlite/hummus + ammendments).
