That sounds right to me. How much of each per gallon?

Okay, had to zoom in.Posted pic of my feed sched in op in ml/gal.
If it were mag deficiency it would have red petioles, that's why I said calcium because they look similar.Hi Dave,
I see your nutrient schedule with the GH Flora Trio Series, which is the exact same thing I'm using for my plants right now. I'm right at about the same week your in also. However, I did not jump to week 3 yet; I kept the same feed from week 2 extended into week 3, 4, and 5 and am now gradually bringing it up to what week 3 is. What you're using is kind of an aggressive feeding schedule that's probably causing a nutrient burn and nutrient lock-out. What I would recommend you do is to flush with RO water for 24 to 48 hours, and then jump back into the feed schedule for week 3 and keep it there for a little while longer. Then begin to gradually increase to the amount for week 4. It does look like a magnesium deficiency, and the nutrient lock-out is probably hindering it from feeding.
You should definitely get a TDS/EC meter as soon as you can. I only use the feeding schedule as a reference for what to feed, but I've kept my TDS around 375 ppm for awhile and am now just getting it up over 400 ppm for this week. IMO, it's easier to underfeed it and give more of whatever it needs than to overfeed. Good luck to you bro. Keep us posted.
Thanks for the info. I'm going to get a TDS/EC meter and do like you said and flush with RO for the next couple days. Do you have a feed schedule you can share with me or have a link to one with PPM? There's so much info out there I'm getting lost in the weeds as it were lolHi Dave,

You're right. It probably is a calcium deficiency. The lock-out plus the drop in the amount of CalMag .If it were mag deficiency it would have red petioles, that's why I said calcium because they look similar.
I really don't know of a PPM schedule, the feed schedule I reference is pretty much the same as yours. But, like I said I only use it as a reference for the ratios of the different parts of the Trio. I know it's counter intuitive for a hydro grower, but I just keep an eye on the plant(s) and let it determine if what I'm doing is good for it by the ways it's growing. And all increases I make are gradual. I base that on the size of the plant. They're all able to take within a certain range and these feed schedules are more of the maximums for the ranges. I'll keep looking for one, because I would like to have a reference for PPMs as well.Do you have a feed schedule you can share with me or have a link to one with PPM?
I guess I was in week 3 since it's the exact same as week 2, though.However, I did not jump to week 3 yet
Just keep increases of your nutrients in gradual doses. Yesterday, I added 1 tsp of each (GH Trio and CalMag) into 18 gallons and added another tsp of each today, so it only increases the amount by 50 PPMs each day until it's to the recommended levels. This morning I noticed a small brown spot on one of the leaves which indicated a deficiency in calcium, ergo I've fed it another tsp of CalMag. Again, for me it's easier to correct underfeeding than to correct overfeeding.So after a couple days of just ro water I'll go back to week 1 feed.
I would stick with RO water while the plant is still rather young. When the plant is bigger and can tolerate higher PPMs, then you can use tap water. The amount of PPMs in tap water won't impact the total PPMs at higher concentrations. However, I recommend letting the tap water sit for at least a day before using to allow for some of the chlorine to evaporate out. But, RO water provides a "blank canvas" that allows you to control exactly what the TDS contain at lower concentration levels.Wonder if I should start using tap water instead of ro water?
I have a Rainsoft water softener that my Rainsoft RO system gets the water from. Do you think the the water could still harmful because it came from the water softener even though its going through the RO system?Just keep increases of your nutrients in gradual doses.

As long as it's PH is adjusted correctly and you add back in the the calcium and magnesium you should be fine.Do you think the the water could still harmful because it came from the water softener even though its going through the RO system?
