Help me

My question will be, my masters, I regularly calibrate my adwa ad12 pH meter and give a pH of 6.4 for each irrigation, but when I measure the drainage water, I measure it at around 7.8 pH, could it prevent salting at the root and getting nutrients? Would empty watering be appropriate if I gave fulvic acid?

I use biobizz fertilizer. I'm moving forward by rising step by step per pot and doing 2 full 1 empty watering, I'm doing 3.5lt irrigation, my latest fertilizer table grow 3ml/L bloom 3ml/L top max 1ml/L alga a mic 3ml/L cal mag 1ml/L Ph6.4, but the problem seems to me like calciu

Less is more. Flushing is damage control. It will not restored injured leaves. Calcium moves up as plant sucks in water from root to new leaves. At this stage, feeding calcium to root is too late. Magnesium is okay thought. For cal mag during flowering, I seperate the two. I feed epsum salt via root. And calcium boron by leave spray.

It looks like pretty bad calmag def. Organic calmag takes longer to show results. Your plant won’t get better, it will only stop getting worse.

Come ti hanno già detto è carenza di azoto e di forsforo. attento che il fosforo viene assorbito a un pH minore di 7 perciò prima di aggiungerne assicurati che il ph del terreno sia intorno al 6.5

It is hungry, in the beginning of flowering it needs more fertilizers! And that's it. Yellow leaves - nitrogen deficiency, brown patches - phosphorus.

Roots constantly too wet or excessive humidity are the cause.

Nitrogen.... first two grows same thing happened to me... I stopped feeding nitrogen as soon as I flipped... now I read should continue for 2 more weeks into flower

wash/flush is only useful if some concentration is too high or trying to adjust ph etc... minor issues usually just take a change to formula and maybe some extra runoff for a few irrigations. need info for these sorts of questios... low on plant? how did it progress? these things help diagnose. those leave are not enough on their own.

controlla la frequenza di irrigazione e riducila.. dovresti provare ad abbassare sotto le piante il misuratore di umidita' e vedere in basso se hai un umidita' piu elevata... controlla anche che ci sia aria che circola anche se le temperature sono un po' basse..
