Kinda looks like overwatering, and lack of proper nutes, with an upcoming ph lockout.

I always go half-strength with the Big Bloom, for both veg and flower. And the Tiger bloom is necessary, lol. The Big Bloom is a catalyst (their words) which doesn't have the micronutes in it. Basically, it's a worm casting and guano tea. The same stuff that's in the Happy Frog. (hmmm...)

Would definatelly try and determine why it's got a 5.2 runoff. That's way too low. Perhaps if adjusting a tad too low, and watering too often, the ph down is wreaking havoc.

Remember, nutes will generally lower your ph. I adjust water to about 6.8ish before nutes. After nutes, it's generally about 6.4ish.

Soilless means without soil...but it's still a peat-based medium. (potting soil) Proper ph range in this medium is 6.3 to 6.8.

Yellowing and Brown Spotting First off thank you to everyone who contributes to the massive amount of knowledge here - it truly is an amazing resource, i've learned so much in the last 2 years. I've got a plant thats 20 some odd days from harvest and she's yellowing w/ some brown spots in certain areas. I've narrowed it down from reading on here to a few things. Can anyone help me out here? I don't think i've spilled anything on the leaves but thats not completely out of the question as i do have to water from above Rating: 5
