Hi Guys, Just wanted to comment that many 12v pumps (rv type) are "demand" pumps with a high pressure shut-off switch. This would complicate their use in hydroponics. So if you go with a DC pump...make sure it's not a demand pump. JD

Your post made me believe that you felt they were connected...but not sure how. So I just supplied the missing information. "Like" and "reply" are below lower right corner of posts and I believe they are only visible or active when you're signed in. JD

Interestingly...too much light can promote nutrient burn by increasing transpiration. as the plant draws new nutrient solution up to those top leaves...the nutrients get concentrated. Oila Nutrient burn from too much light. Maybe that's what happened. JD

I think maybe feeding too much. Since it's coco with no inherent nutrients...you have to feed early. But really low like 200-250ppm. JD

Not a downer Tange...being human means we experience loss. It's just part of the program...so you're not alone in your loss. And certainly not alone being a gardener. Good thoughts your way... JD

I did that once with a "helmet head" seedling. Once I got the seed shell off...I watched it about a half hour. I swear I could see the leaves unfolding...but then I was high like usual... JD

Good morning StMH, I am not naturally an aggressive person...in fact pretty mellow. But I've been growing for 50 years...so perhaps there's a correlation. Another thing growing did for me at my current location. I keep my grow space clean and organized. But one day I realized that all my...

Leave them for now. Later, once other upper leaves grow...then defol. under...they are the plants energy source. JD

Nope...when you count up 3 nodes...don't count the cotyledons unless there are fan leaves there too. So I'd go above that node that you are under. Up one node. JD

I was thinking the same thing. Early...but worth treating. !/4 tsp/gal ES. JD

Yes...tall enough. I see 3 nodes above the cotyledon. First topping is above the 3rd node. Careful with the new growing shoots... JD

We used to back in the 60s and 70s. If it's good weed...the leaves will get you plenty high. I prefer making cannabutter with them. JD

I use movers too. I like that they hit leaves from different angles as they move. Easy way to mount lights too. Hey...with the 315 you'll be at 56 watts/sf which is a little high. I'd just go with the 600. JD

yup...looks like Mg deficiency, but not enough info to call it. JD

I remember seeing a sativa bud shot that looked just like that. I described it as a punk hairdo. That a sat? JD

Whoa botman...don't add anything else till you know what's going on. My personal reaction is that you are using too much stuff. Soil has nutrients plus castings and 700 ppm feedings. You have multiple deficiencies and burnt leaves. Just use water...maybe a little superthrive...and get it on...

Dt...looks ok to me. What water are you using? JD

For good help...it's best to just start a thread with pictures and details. But as I implied in my post that you quoted...it's all about the water. So if you're giving it crappy hard water...that would cause that. JD

Not impossible...low yields and long flower times is about all Ace seeds sells. Landrace sativas. So I thought you were trolling him trying to convince him to buy pure sativas. Which are super hard to grow. I thought you were being mean. So call me a dick, that's ok...I can deal with it. 8) JD

Seems to be available...but Jordan of the Islands doesn't list it. I thought it was their strain. JD
