This is my first aeroponic grow...not sure if this is a deficiency or over fert? but a few leaves are turning brown...It has progressively getting worse...plants are about 3 weeks into veg. Oh and one plant is doing weird things with the leave...looks bubbly...thanks! Thanks for any input!

I have started nutes...I can't believe it would be over fert...if anything a deficiency...I actually started super low on the nutes. I'm only using a week 1 feeding schedule, because my last grow when i followed the directions, i over fertilized everyone...so this time I'm cutting everything in half!

Way too much nitrogen. Depending on the strain, you may need to go half strenth on nutes,
check ph, and cloro and cloromene can be nutralized with some vitamin c tabs.just an 1/8 of a pill in a gallon will make the water healthier for vegg.
Looks like a hydro in hydroton? Are u on a water cycle?

I'm already at half...I'm only on week 1 schedule and the babies are 3 weeks vegging! I'm using botanicare stuff...Could it be PH flucuations? Mg def?

They are in rockwool filled with hydroton....I would have preferred if they would have been without the rockwool, but that's the way the girls come. They are in a aeroponic spraying system on a 6 on 30 off cycle.

went to the hydro store today...they thought it was a chlorine issue instead of a overfert. I wasn't using RO so, i got some RO water and magiCal...I'm going to flush with RO water and then add nutes to fresh water...hopefully everyone will be looking better in a few days!
