New grower needs your help please

These plants are 3 weeks old. They were going beautifully till 3 days ago when i started noticing signs of what is displayed in the pics.
This is a bubbler unit.
growing medium: rockwool cubes and hy Droton fired clay pellets.
nutrients : hydrotech Zeta 2 part liquid nutes
lights: 2x coiled cool natural light flor. 6500k 1600 lum.
2x 24" plant and aquariium flor. 5000k 1275 lum.
2x 24" "sunlight" 6000k 785 lum.
the dome between the two is a fan
oh about the same time i moved the plants from the ebb/flow (this last sat the 21st) to the bubbler i sprayed them with dr fausts fulvic acid 1:200 dilution. then made the mistake of spraying them again the next day.was only supposed to use as a foliar spray once or twice a month. If someone could please tell me what is wrong i would greatly appreciate it thnx:thumbsup:

it's a calcium deficiency. get some cal/mag, 5ml per gallon, and it will fix them right up ;)

love, lestie

Thanks for the rapid reply!! will be going to grab some cal/mag today. the hydrotech zeta line does not include trace minerals just learned that this morning. should i also get a booster to add all trace elements as well?:thumbsup:

you need a formula with micro, i highly recommend gh 3 part, great stuff.

my line up is:

gh 3 part (micro, grow, bloom)
cal/mag
AN hammerhead (omg, this stuff is fantastic!!!)
superthrive
ph up/down

that's all you need for an outstanding hydro grow ;)

love, lestie

i actually got convinced to stay in the hydrotek line. i grabbed the bee one for the calcium and the booster pak for the trace elements. added to my nutes. how long before i notice an improvement? and will the disolored leaves turn green again or should i just get used to the discolored leaves? thanks again.
here is my complete line
hydrotek zeta "grow" parts a and b
hydrotek bee one
hydrotek booster pack
dr fausts falvik acid.

man i hope this works :D
