Upper leaves and new growth drooping, bottom half of plant looks healthy

Its been a while since I've been on here, but my plants are doing weird drooping on the upper half of the plant the bottom leaves are health and standing up ..your help is needed! Thx in advance!!

4th week of veg
Soil:happy frog
Light:600 watt mh
Pots: was in 2 gal fabric pots/now transplanted to 3 gallon fabric pots
Ph: of soil run off 6.5
Water: tap water 20ppms
Roomtemp: 70lights out/ 75to78 lights on
Rh: 30to50
Bugs:none

So my plants have been getting straight water for 3 weeks since happy frog have plenty of food ,and 5ml calmag every other watering, I water every 3 to 4 days pots are dry & light. So its definitely not over or under watering. The plants are about 4 weeks old at week 3 I gave them a light feed 300ppm floranova grow 180ppm calmag =tottal480ppm plants looked fine, 4 days later I watered straight water with ph 6.5 a couple days later the upper half of one plant is drooping bad! But only where the lights are hitting the plant. The bottom half of the plant looks health. Now all 6 plants are starting to get the upper drooping I've done days of reading and searching forums every thing says overwatering but its definitely not that. There no brown spots burning or nothing on the plants just upper leaves and new growth drooping.....any help is needed....

*Ive raised the light 2 feet waited 2 or 3 days/ didnt do nothing
*so then i transplanted from 2 gallon to 3 gallon pots with fresh happy frog soil 2 days ago/still drooping

I'll post more pics in a couple hours

runoff EC ?
if you use tap water you dont need this calmag i see everybody use it here it brings more problem than help imo
excepted when used by pros that know it
i never used it and never had problem

maybe there is a salt accumulation in your soil

Ec run off is 1700 ppm @.5 its fresh happy frog soil so that's the nutes in the soil. Before I transplanted a couple days ago the run off ec was 1000ppm,every time I tested fresh happy frog soil ppms are always 1700 to 2000ppms
The only reason I started using calmag every other water is because my tap water ppms out the faucet is in between 0 and 20 ppms thats pretty soft. My water ppm use to be 200 ppms out the faucet but about a year ago it changed ‍ to low ppms so I been putting calmag back in ,But I'm gonna cut the calmag out and just give plain 6.5 ph water

& they've only had that one feeding at week 3 other than that it's just been the nutes in the soil they been using

Heres a few more pics

ah yeah your tap is very soft .. ok for the calmag
your runoff is very high .. more than 3.0ms
probably why your plants looks so sick..
i would only give water with a lil bi of calmag for a few waterings

Thanks for your reply! your help means alot. I'm gonna give them straight water with low cal
Mag every other water for 2 weeks and see what happens. Quick question?? Some one said they looked hungry, if they were hungry wouldn't they yellow from the bottom up?? The bottom leaves are green

Bottom up yellowing is only if they are hungry for Nitrogen. And Nitrogen is only one of many nutrients.

Personally I think you use calmag too often. I would leave it away for a while.

imo the soil became too hot meaning excessive salts dried and accumulated inside it
the excess of some element will block the assimilation of the others
like the nature things must be in balance

see the mulder chart

the deficiency is on the new leaves meaning the deficient element is an immobile element
Iron is blocked imo, probably by calcium or phosphate
Nitrogen is a mobile nutrient, yellowing start on older leaves (bottom)

Makes sence, that's good info , sounds like your saying the extra calmag is locking out iron, So no more cal mag for a while , I just transplanted to 3 gal pots with fresh happy frog soil wich has nutes in it so I'll just give them plain ph'ed water for 2 weeks

if your soil is already charged in nutrient yeah plain water .. but i would put a bit of calmag inside, but no excess.. if you put just tap they will be deficient of calcium magnesium. i would just add calmag til 0.1 or 0.2 ms and water with it. then when they will need regular feed just give em 1.2 ms total at each watering. 0.2ms being calmag

1.2ms ???? Is that suppose to be1.2 ec

yes

Hit the soil with some lime

Cal mag is not needed if using tap water. Tap water already contains these minerals, are you letting the tap water sit for 24 hours before using it so the chlorine can evaporate out of it?

you assume tap water is the same everywhere, which is not true

Yeah assuming, but im pretty sure cal and mag are both naturally occurring minerals in tap water.

his tap is soft it dont contains minerals
