no, that's likely a deficiency or root problems. Bud rot is impossible to miss, or to confuse with anything else, it looks like a huge mass of moldy rotten garbage

and your cycle? i'm asking because more light = more problems... if the factors aren't right. A plant can be very happy at 200 PPFD for 18 hours and start going crazy if you change her to 400 PPFD

How much light is she getting?

she looks stressed honestly... i think there's a problem in the root zone, coco is sometimes dirty or salty. Did you prewash the coco? Why not coco/perlite? Coco by itself has never been a good solution for me. But with 30/40% perlite its bomb also pure coco stays so wet that is a magnet for...

Everything is relative. Mostly i see people just fill up as much space as they have and improve as they go. The standard right now seems to be Gavita DE (or equivalent) or Strip Leds if you wanna be long term and efficient. Tasks involve all of those you mentioned, and usually 2 people can take...

only defoliation i've ever done is getting rid of: leaves on top of each other leaves shading bud sites leaves getting almost/no light leaves blocking airflow .. combined with SCROG and LST has propelled me to 1.7 gpw (LED) without CO2. But i've no idea if the defoliation has got anything to...

funny post

I'm wondering, what kind of problems did you experience due to the summer high temps? Nice to see what a grower with so much experience has to say about current LED tech!

reduce nitrogen content lower medium humidity (aka STOP OVER WATERING, but the other 2 are also growth factors for algae) avoid light reaching medium

If you're still messing with that board i'm willing to help. Honestly, i don't think you'll get MUCH output from the red diodes, but they will definitely help. And you can definitelly try to just run the whites, and it will for sure grow bud

i wish i actually used half of the seeds i store :( maybe one day

looks neat, my first reaction was: nice! i can see that a lot of work has been done on that wall... Looks clean for someone that can see the kind of automation you're doing especially for a DIY or if you're in humboltd... but its definitely a very bad shock and fire hazard... I know some of...

I always wait until they are well established and kinda (visibly) hungry before feeding them... The way i grow is "less is more"

Your 40% humidity is working in your favor... As long as there's enough airflow and water for the roots you should be fine even if you hit the low 90's for a couple hours... But regarding your question, i advice you against using the CFL's at all, they suck pretty bad... You're better off...

looking good now, godspeed

My 2 cents: 30C is still OK =] Make sure you don't reach 35C(95F), that's the trouble zone. As long as you get your airflow dialed in, and keep your humidity levels below 60% (which is actually a little high for flowering) you should be good.

how old is your plant? 600ppm seems like quite a lot of nutes for a plant that small it may be getting nutrient lock'd

I've used them a lot, and i think its your water... I get 7.0 water with less than 150ppm, i know for sure i can use a teaspoon of Maxi per gallon and the PH will be perfect every time... Something you could try is buffering the water BEFORE adding the maxi, PH UP after nutrients tends to...

second this with passion.

i know this is a somewhat old post, but if you wanna maximize spread and even-ness then you gotta distribute the lights opposite to what's going on in that picture. (focus on the edges, instead of the center) Light naturally gathers in the center of the light and drops as you reach the edges...
