Yellow spots on leaves

you very much for the advice, today I also saw the same yellow spot on another plant, since yesterday I am giving it water with a pH of 6.5 that the normal one at home is at 8.2, I hope they will recover soon, last question, you advise me to cut the leaves or do I leave them for now so as not to stress the plant too much?ty

It's the start of a calcium deficiency - and just because you aren't seeing it crop up in your other plants doesn't mean it's not there (and will likely affect your other plants soon). The reason for this is the amount of nitrogen you're giving her since your pH is spot on... this has caused a minor lockout of calcium which can be taken care of by simply watering her with plain pH'd water for about a week... and then when you DO give her nutes again, you've got to cut way back - like in half!- on your grow nutes (the alga grow as this contains the most nitrogen). You should also be cutting it back in your other plants right now - all of them are in flower and plants in flower need SOME nitrogen but not a lot... so decrease the alga grow and you can pump up the alga bloom now. I would also recommend 1tsp calmag per gallon given only once a week... It's good you caught this early because if it had continued, you would have been forced to flush the plant and that sets things back quite a bit... Good luck!

Hi there How it is now I wouldn’t worry… i would wait to see if anymore pops up anyway else, but she does look rich on nitrogen though i would check the dose in that booster your using and maybe cut it down abit if it’s high and nitrogen Best of luck 🌱

from that shine i would say you overdose nitrogen from droopiness of leaves i would question your watering habbit those rusty spots are either : mechanical damage from leaf rubbing leaf ( MY PERSONAL VOTE, after looking to your diary, nothing to worry, unless ..) first signs of ph issue calcium deficiency, could be caused by excess of nitrogen blocking absorbtion of it or too intense light and need as supplement to cope heat and light intensity . From all my mistakes, i would do such short list and would find mistake . Hope it helps ! Happy Growing !!!
