Looks like toxicity. Bring your TDS ppms down to about 1000. Also looks like you have gone too hard on some of the bloom nutes. Other than that, I would discontinue anything that has a good amount of N in it. You're good though, fix this and they will be butes.

And yes, calmag is an absolute necessity.

Help Identifying Ailment! BlackBerry Auto on week 6! Nutrient deficiency? Cant find anything online similar.This is my second grow since switching to hydro. Growth has slowed a lot. Leaves are getting brown spots and almost look like they're being eaten but no pests can be found. No root rot, I dont think I'm over watering them. Since I started hydro it's been a real challenge.

Leaves have some spots My auto flower has started presenting some spots, it's on week 3. But I've seen these marks since the beginning of week 2, been measuring my ph and everything looks fine. Maybe the super soil is a bit too strong, and it has to get used to it? The lamp is 27 inches away.

Taken a few pics of one of the affected leaves. Thinking potassium deficiency but not 100% sure Was away for best part of a week & had someone else watering them, just plain water (may of spilt on leaves?) Leaves seem crisp to touch as well as the yellow/brown colouring.

I found a few holes that looked like a Caterpillar was eating my plant but I haven't found any pests. Perhaps a fungus??? Anyone know what this is due to? I sprayed bubba with neem oil just in case...haven't found anything since.

Hi there, does anyone have any idea what the slight mottling is on the leaves of two of my plants. There are close-up pictures under Day 27 in Week 4. The discolouration is present across multiple leaves, but seems to only be happening to two plants out of 8. Thanks!
