1st Photoperiod, Sour Diesel by IlGM

From about week 6 onwards.

Slight nutrient burn on the tips, otherwise it looks fine. Yellowing is caused by lack of Nitrogen. It is an easy fix and can be fixed in one feeding. The brown spots could be very early signs of Manganese, however if it isn't fixed by your cal-mag then flush and re water with 6-6.2 ph water. All things considered, the plant still looks good.

I trim my big fan leafs if they are covering up to much of the plant. At week 9 you defiantly can defoliate your extra leafs. I Lollipop right before I start flower. I remove anything under my canopy that will not get adequate light to produce. This will enable the plant to focus its energy on the bud sites that matter. Don’t worry, sometimes it may look like you took a ton off but I promise that it will be ok.

They spent millions on R&D..........they would not recommend something that is going to disappoint its' customers. They have their guidelines for a reason. Remember............ it is very easy to fix a slightly underfed plant, but very, very hard to rescue a burned and damaged over fed plant!

Okay. So, you're in pre flower stage. So max ppfd isn't needed. Nor should u lower your light that close as its still a growth stage. Once pre flower is over you can then even out ur canopy by HST'in / supercropping. Also, to slow nodes that are growing more than others. Take a few of their bigge fan leafs off. This will slow tat nodes growth. (But becareful as ur in a stage where any major Defoliations shouldn't be done) but 2 sets of fan leafs off nodes won't cause too much stress it'll slow that nodes upward growth. Really its not a major thing to worry about. DLI, good feeds methods, air flow, temp and no light stress. These things will suit u more in getting a successful grow. After pre flower that's when light intensity comes much more into play. Good

Magnesium. Symptoms show in the leaves 2-3 weeks after the problem starts in the root zone. Remedy will take 2-3 weeks to show in the leaves once cal/mag is increased. Cal/mag weekly is probably where you are at.

Too much nitrogen in feed. Possibly a salt build up from not getting proper irrigation when adding feed.

Week 6-8 is a good "average" but it will still be largely based off strain and conditions. Overdrive is a finishing product that's intended to increase your terps/essential oils, Advanced Nutrients bulking enhancer is a product called "Big Bud". I've never used Advanced Nutrients so I can't say how effective it is. I do use a similar product from General Hydroponics called KoolBloom and I like the results. Two weeks is a bit much for your flush in my opinion. I do 1 week in soil, 4 days in coco or 24 hours in hydro. You don't wanna start it too early or you could miss out on some bulking.
