I am gonna lean on a ph out of line in substrate due to plant is absorbing lots of potassium and phosphorus. Raising ph as it eats. Now causing first signs of lock out for both those nutrients. I don't feel it's cal mag all in your case.

It is not cal/mag, but burning from feeding too much or too often, or both.......as evidenced by the super green foliage in general.

Kinda hard to see in the pics. Can you get a close up shot of one leaf? Calmag def shows as rust colored spots normally.

Seedling advice Hi, my light was at 60cm with an average humidity of 70 degrees Celsius. There’s slight dryness around the tips, yellowing, crispness. Remedy thus far: I moved the light up to about 75 cm, it’s a 100W led. Humidity also dropped to about 60 degrees. Any advice to remedy?

Leaves yellowing These leaves are stressing me out. I’m not sure if I’m having a lockout or if I’m not feeding enough phosphorous. Either way, I’ve been using 3 ml/gal of tiger bloom, 3 ml/gal formulex, 3 ml/gal big bud & 1tbsp of molasses for feeding. What do I do ?

Leaves turning yellow Old leaves die,mig-age turn light green,new stay green.Is this normal for just week 4 of flowering on my auto? Do you think it might be ready sooner than week 11? Or is it just a problem? "feeding/watering every 4 days,never used cal/mag supply,medium=soil light" Thanks growers

Yellow parts on very young leaves She's only 2 weeks old and some leaves started yellowing. Should I be concerned or it's a normal thing? Watered her a few times with distilled water (no nutes). Also, there is about 30-40cm distance between the plant and the light (SF1000, put on ~50 power)

Leaf discolouration. Nutrient deficiency?Leaves are discoloured and clawed. Started about a week ago with yellowing of tips and clawing at top of the plants. Now lots of leaves are slowly changing colour. Thought it was nitrogen toxicity but my runoff is 330ppm. Are they deficient in nutrients?

Lime green leafs I noticed the top leaves are turning more lime (see pictures of day 74). I used the same nute ratio for weeks. Should i do something, or is it simply the plant reaching the end of its life?
