Deficiency or overload?

[GoAuto6]

8 hrs outdoors 12 in under ho t5 and 2 300 watt Chinese led panels temps inside 28 celcies and rh 37 percent pH of my tap water is 8

8 do you buffer it down to 6.5? I'd say pH is the culprit. Do you have a good soil probe like the accurate 8?

Just use pH down in my water. My pH meter might b dicky tap water is reading 8. Did drop it to low to 5.6 started to see the burn and yellowing so flushed a bit today with the tapwater. Then ph'd a bucket to 6.2 and added some more organic fert chook shit and such

-- mate, what soil is this? If you have burning, and haven't added nutes yet, then the soil is suspect,... do NOT add more fuel to the fire with that product! .... I'd say she looks pale all over, unless it's the Sun and camera doing it,... that puts in-pot pH suspect as well,... you need a soil pH probe to test this properly, otherwise it's the dubious run-off test,... tell more about the soil, and if you amended it,...
Do you calibrate your pH meter? Store it in the proper solution? Don't do that, and the accuracy will go to shit, fast,....

Iv used a two different compost soils one had a slow release feet in it. Both from bunnings. No calabration or storage solution. Am thinking of re potting not ideal I know but its getting worse. Greened up a little but heaps of burn

Plain pH water to run off of at least 10%. Structure looks healthy though so that's good.

well, time to flush then,.. don't repot, the trauma will not be worth it..... flushing is the only way to deal with potential off pH in the pot, and excess nutes,... usually you pour 2-3x the pot volume through using good water, not overly hard,... yours isn't that bad so maybe 1-1.5 x will be enough,... is there any perlite in this mix? Straight unamended composts can be pretty heavy,...

Straight compost and this is them after a flush 2-3× volume.

OK, when dry enough to water next, start your nutes again, a mild dose at first, including Ca-Mg,.... hopefully the flush has purged the excess and got the pH OK, so she can start taking up nutes again,....
