Advanced nutrients perfect ph and humboldts calmag
About four weeks into flower
I use ro water

most recent feeding watering was about half gallon per dirs with extra liter of calmag

I’m not stressed coz she is smokable but
Hate to see her so

I am thinking salt buildup?

Hey man, ahoy! What's your pot size? I have a question, what is "dirs", I used advanced nutrients pH perfect in the past, and the measurement I used was the one on the bottle 1ml/L at first and then adding half a milliliter each week untill I reached 3.5ml/L, although in the bottle says 4ml/l. A liter of calmag sounds like a lot. How many liters or gallons was your feeding mix?

3gal. To clarify, 2 ml of calmag in a liter of water in addition to approx 3/4 gal of water and AN per the dirs of 4mg per liter each. I did lighten up the nitrogen that last feeding tho to 3ml per liter since the calmag adds some
Could be...?
When addressing the calmag deficiency, it overloaded N? Humboldts calmag is 2-0-0.
In addition to the regular feeding during this flower stage, maybe too much N?

You can totally cut the nitrogen at this point.
 
Sometimes if you let the soil dry out too much, the sudden inrush of nutrients can potentially burn the plants. Dont quote me on that, though, but something to look deeper into, perhaps. Probably too stoned for this. Cheers all, happy holidaze.

Looks like nute burn, to much nitrogen not enough phosphorus? What ppm you feeding them?

i don't have a ph/tds/ppm/ec reader. just trusting RO water and perfect ph system from AN.



thanks for the feedback everyone. I've decided to cut the affected leaves, and i've watered to run off with 50% diluted 2-4-4 with a shot of cal mag thrown in. will monitor remaining leaves.
 
Unfortunately, AN Micro grow bloom + humboldts calmag doesn't permit me to just eliminate nitrogen...can only reduce it by skipping micro.
P & K have 1-x-x of N. And cal mag has 2-0-0

will take fertilizer recommendations to avoid this problem in the future, if anyone has. sensei? others?
