Follow up grow information

Please check my past posting for what stated this whole mess. The other photos will tell a better story. Iâ??m sending all the information I can think ofâ?¦..

Plants have been veging for about a month and a half. I use a 10 gal resivor Fill & Drain system
Grown in 4 in rockwool cube. I use the Ph drops to read my Ph. I try to keep it in the yellow 6.0.
I use stor bought water They are fed 6 times a day for 5 min. each time a day. Iâ??ve woundered if my watering cycle is a problem, but being rockwool I canâ??t over water. Or can I???
I use Technaflora products, BC Boost, Grow, etc... Because of my past exper. I do not follow the total amout to use. I've been told always use less cause ya never know.....
My 1000 w light is on 24 hrs. during the veg cycle. See the photos I donâ??t think my lights are too close. Does anyone else?

So this is where my little adventer picks up. As I stated earlier, I flushed with store water only, untill the PPMâ??s stopped rising in the resivor. Back under the light and started with ¼ strength nutrients this gave me a starting PPM of 400, A few days later increased to around 560PPM. As you can see, some how my nutrients are fucked up again!!!!!! Christ, Iâ??ve tried doing things so carefull, I guess itâ??s time to flush again. I really need some help Did I not flush properly? Anyway, help from someone who really knows will be greatly appreciated

Sorry, in your other thread I failed to notice you are hydro, that rockwool cube is small, and from what I know maybe cut waterings to 3 or 4 and up the time they get it from 5min to 10min, 6 times a day seems like a lot to me. BTW your plants don't look bad at all; some minor crispiness and yellowing happens in hydro too (can happen) but they don't look like they're suffering.

I think your PH is a little high for hydro, optimum ph is 5.5-5.8

and I believe your plants are experiencing a calcium def. possibly look into your nutes and change brands

you can test this by treating with foliar feeding with one teaspoon of dolomite lime or Garden lime per quart of water, Or Any Chemical/Organic nutrients that have Calcium in them will fix a Calcium deficiency. (Only mixing at ½ strength when using chemical nutrients or it will cause nutrient burn)

it wont repair the damaged leaves ofcourse but it should stop the issue

here is an example of calcium just starting
