    That was my guess. Which sucks because they made it sound like all were needed for the best results.

    I'e uses the trip in the past and have had decent results. This is the first time using everything.

    Local hydro shops always push EVERYTHING . Actually the plants need very little, we try to force feed way to often and over water a lot.

    at ph 6.5 your plant may not be getting enough phosphorus and or magnesium. try bringing your ph closer to 7

    Do you have a ppm meter? It would help with flushing, takes some of the guess work out of flushing. Don’t keep flushing, that’s called over watering. Flush once really good and come back on the last pouring of water with an all purpose nute and cal/mag. Make sure your pot is draining

    People, and this includes myself, have spent A LOT of time identifying deficiencies, like it's the most important thing to know what exactly the deficiency is. IT IS NOT.

    Why? Because in almost all cases, be it some type of def (or toxicity), regardless what it is, the solution is the same:

    You will flush your plants with pHed water with the correct pH (soil: 6.5, hydro 5.5-6.0), and then give nutrients in the appropriate dosage. What *exact* deficiency it is/was is not even that important. (The other issue is, many deficiencies come in a combo, so the symptoms can include signs of all sorts of deficiencies and are not always that clear, even for me as an "experienced" grower.)

    Most deficiencies/toxicities come from incorrect pH anyway. (Eg. watering with non pH-ed water, or overfeeding which accumulates salts in the soil so that the pH is off after some time, leading to deficiencies).

    Flush --> (to correct your soil's pH) ---> water/feed with correct pH ---> 99% of all problems are solved.
