Never had this problem before..

This is probably a common problem, but I haven't come across it and I can't see the images in the stickied post. +rep for helpView attachment 1073989View attachment 1073990View attachment 1073991


edit: the images are rather blurred (thanks to my flash) but its dying off in small circles.

Reading up it looks like a calcium deficiency. That sound right to you folks?

Looks to me like P toxicity.

P toxicity and calc def go hand in hand.

Nailed it.

I'm currently working on the opposite problem right now in coco. Calcium toxicity with Phosphate deficiency (damned hard water). These nutrients play off each other and need to be in balance for certain. You've got the reverse issue right now, probably from a bloom booster.

You're sure it's not spider mites, right?

but saying its P toxicity will tell him to lower the P fertilizer rather than adding more cal fertilizer, which is what I would start with.

Ya I checked them pretty well, no bugs or webs; plus my PK isn't showing similar symptoms. I am using Tiger Bloom though so the problem makes pretty good sense. I water tomorrow so I'll be fixing it then.


Thanks everybody!

Are you using hard water ? pr RO water ? What i would do .. Ro water add cal mag to 75 ppm or 100 ppm.. then give it to the plants the problem will slove in 3 days ..

if your in soil its easier and cheaper to have your water analyzed by a lab, then take measures to get the correct ph and ppm, than it is to run a RO system.....

If its calcium they need I'm just gunna water them with some milk






In reality I'll probably give them a flush with a little dolomite lime and stick to molasses for the rest of the grow, they have barely over 2 weeks left at this point.
