The soil is the best I can get here in Australia unless someone knows better(?)
I added some cal magic yesterday with some fresh water. I donāt have any Eason salts but Iāll grab some ASAP.
So best option is to just water it out until the epson salts?
Iāll turn down the heater and clean up the floor.
Foliar spray? Not sure what that is.
I hadnāt added any nutrients until about week 3 then I added 1 cap full of the seasol and 1 teaspoon of the thrive all purpose fertilizer.
Thatās it. As for the ph my reader says ph6 at the top of the bucket and 4.5 at the bottomā¦ maybe my reader for ph is no good even though itās new.
Not sure if I missed anything?
I appreciate your help.
Thanks legends!

Iām in Australia, you can get quality cannabis friendly soil at any hydroponic shop. I use canna professional and their coco nute range.
A good PH pen is essential, i recommend blue labs but budget electronic ones work too but need more calibrating. EBay and Amazon both have specials when buying both ppm pen and PH.
Try to keep temps under 28Ā°
Being new myself I researched so much on here and found thereās sooo much more to growing than just good seeds.

Just looked at the canna range. Itās in WA so Iāll see if I can find anything near me in Sydney. Just purchased a proper PH pen so will see how that goes when it arrives.
Thanks for the tips

Update. Lowered temp. Changed water and added cal magic.
Also no Iām not just testing them with the tester in the soil. 
There are not drooping now 
Still require the Epsom salts you reckon?
Just found some canna soil on eBay. Appreciate the heads up. Was just getting the best stuff from flower power but this stuff looks way better.

Iād also recommend a clean grow space, uninvited guests love places to hide and once they come itās war of a different kind 
When I had similar problems it was because my PH was way off. ( because Iād make a batch of nutes and use half one day half the next feed ) ā¦ didnāt think the second half of my mixture would creep up in PH over 2 days 
My only solution to my problem was to flush with PH 6.0 water ā¦ they bounced back 3 days later and yellow leaves started to go back to green.
Trying to amend soil or nutes is useless if you have ālockoutā they canāt absorb the nutes needed because the soil is to high or to low.

@Shanewise23 Foliar spraying is simply taking a spray bottle and putting water in it and adding in the cal-mag. You do this right before lights out, and ONLY before the lights are going off NEVER do this when they will have the lights on for any extended period as the water droplets act like magnifying glasses and will burn your leaves.
Here is a link, non-cannabis or competitor related, to a good understanding of the difference and why foliar spraying can work sometimes better than a top fed through the soil means. Not to say donāt do soil watering but this can help with serious calcium and magnesium deficiencies.

Epsom salt at 1 tsp per gal. Watering to 20% runoff is the preferred amount during any waterings. No need to flush the soil quite yet either if that was what you were implying.
They look like they are bouncing back rather quickly which is a good sign. The brown necrotic spots and leaves will never go back to green and the tips may stay that yellowish because they look like the tips were pretty far along, but the light coloring between the veins will start darkening back up.
Yeah I donāt feel like the soil PH probes can necessarily workā¦ there is too much solid material and the probes can only read liquids. That being said, I used to work for a water restoration company years ago and their moisture sensors they stuck into drywall seemed to work rather well. So maybe if the soil PH meter were something like a really high end piece of equipment, our moisture meters cost over $500 where I worked, then maybe there is something to it. General consensus here is theyāre too inaccurate.
I would suggest that, until you get your PH/TDS meter, using as little nutrients other than cal-mag as possible. Keeping the temps lower and trying to increase your humidity a little should help slow down your watering schedule.
Your light height. I am not familiar with the light maybe someone else is but I would think that 3 feet is a considerable height even in veg. There should be a manufacturer recommendation though. I would wait until you have things dialed in on the watering aspect though if you find a suggestion for anything lower. Too many changes at once can result in something changing for the worse and you not knowing what caused it.
