Your older grows didn't show this kind of leaf damage but recent ones have, so the thing to do is figure out what changed between the two. Different or reused soil, different nutes, changes in RH and temps, location in your room, different lights...whatever it is these leaves look exactly like the some of the ones from the Seedsman grow last year (was it the Northern Lights?):
Can't be a coincidence.

If you want to confirm the last results start with new soil.The soil that I made the test in last night is still sitting here nothing wrong with it I don't think you got the lids on it still slurry do you think I can use it again today I want to retest?
I'd start with .5 Tbs/gallon of soil.I just don't know how much lime to give to those three plants. Navy three more tablespoons? 6 who knows..
I would start by taking a solo cup of the soil you're going to use, water it to runoff, wait 4 days, and then slurry test it. That way at least you'll know the pH going in. I find the FFHF I use is in the high 5s rather then the 6.3-6.8 they say it's going to be.I would love to grow one all the way out 100% with no complications
I meant to keep the cal mag bottle since there may be a time it will come in handy.Tell us what bottle? I meant toss
