This one looks like it didnβt like the level of nutrients you gave the other girls. I would give her just phβed water the next time you feed the others and see if she perks up for you.

To my outdoor growing gurus.. How do I schedule a regular nute feed????
doing an outdoor grow and dealing with a consistent rain schedule every couple of days. Can i supplement a feed and give more water (think that's a bad idea), or do I wait until the girls are thirsty again to give nutes? Possible too much rain stunting growth?

3rd week since 12/12 and chlorosis is getting worse !!! Will my crop be crappy ?
Brought EC to 1.6, added 21ml of calmag, had to add 2L of osmosis water because the EC was 1.78. I changed the bad Ph probe and I let it fluctuate between 5.75 and 6. Should I remove the aluminium foil on the pot to let them breathe ? Not sure they are overwatered, I'm desperate

If my ppm intake is about the same as my ppm runoff but my pH runoff is way lower than intake should I be worried? Or what should I do?
If my ppm intake(705) is right about the same as my ppm runoff(790) but my pH intake(6.7) is off from my pH runoff(5.9) should I be worried or be trying to correct something or should it be fine? Humboldts Secret nutes, Glueberry Og Auto, rh48 temp74-76, advice appreciated.

Rusty Leaves
3 upper fan leaves have "rusty" brown spots on the upper side. Hard to spot, hard to capture on camera. I also have slight "clawing" on many of the upper leaves. Mg/Ca lockout because of nitrogen toxicity possible? DoesnΒ΄t seem to be fungi, as there are no spores to rub off.

Magnesium deficiency? How to cure it?
Is this a sign of magnesium deficiency (my other plant has similar spots)? If so, I've read online (on the Canna nutes website) that I should spray the leaves with Epsom Salt (2% solution): is this correct? Any other suggestions? Thanks in advance
