Hey guys im growing 3 autoflowers in a Aeroponics system (GH rainforest), now the ph was off i got that fixed, my sprayer motor apparently turns so some roots got tangled, untangled them and installed the mid pipe so the motor doesnt spin and catch on roots( dumb move on my part) my plants seem to be growing fine but some leaves are irregular and some spotting, i am not sure what the proplem is i upped the nutrient dose to the full 1/4 strength ( general hydroponics flora), added about 40ml calmag to the 50L base, i will upload some pics i really dont need this to get worse i cant figure out why some leaves are like that, i do not have a ppm meter still waiting on it, i do have a ph meter reading 6.12 atm . Thia was done less than 24hrs ago. Thanks guys

pH is the source of almost all problems in hydro, just not light or temp.. But it never hurts to have a good foliar spray to balance it all out. When you get a pH problem, spray them with some Optic Foliar while you correct the problem. That supplies a temporary source of nutes directly to the leaves while you sort out the water availability.
There is no telling how accurate that reading is. You will know better when the new meter gets there. But 6.2 is where trouble starts on the high end. and 5.4 is where trouble starts on the low end.
chemically speaking you want to be as close to 5.8 as possible. the forms of each nutrient shift depending on pH, and some are not in a plant available form outside of those boundaries. Here is the chart:

Good stuff from the Good Rev. I like to see my pH swing from 5.7/ 5.8 to 6/0/6.1; had some recent cal-mag problems that pushed me closer to 6.0/6.1 and other than the cal-mag deficiencies going away I didn't see any real difference. If you've stayed at 6.1 or lower you should not have any problems with that.
But a few questions - what is your water source? City? Softened? Well? RO?
And you say you went to the "...full 1/4 strength"; what does that mean? In exact mL dosages per Grow, Micro, Bloom; any additives?
You added "...about 40ml calmag to the 50L base," does that mean your reservoir is 50liters? And if you're RO, you will want to increase the cal-mag to 1mL per liter / 4mL / gallon if you measure that way.
