Man i had several strains in there and some ate heavy and some didnt, so its hard to say. My cookies could have handled 1.5-1.6ec throughout the grow no problem, but that would give other strains issues. With hydro if the plants look good and ec in the block is stable youre probably good. If its too high you'll see the EC in the block spike overnight and see signs of overfeeding within a day or two. I think youre likely in the sweet spot if the ec doesnt drift much. But be aware you might need to dial it back slightly when you flip to 12/12. The reduced length of light caused mine to spike the ec after a few days, I had to shave a few points off for a week or so but it eventually ramped back up.
If i decide to go rockwool again next round which im leaning towards, im going to monocrop my best strain to keep things consistent.
Oh nice that's def good to hear. Thanks for the tip you're reminding me I used to do a flush right before flip for this reason. Definitely would've forgotten that if you didn't mention it. I hope you do another RW one for sure, definitely a fun one to follow. Yea I did monocrop for this one too just to minimize future headaches lol, not that skillful yet to go wild with a bunch of strains. Thanks for the peace of mind
