Yeah that’s what I did but I think I waited to long to put 1st in

 

[Jsimp342]

Ended up moving some branches around under more net for the last time, they seem pretty even now. Look healthy as can be so far!

Also I am curious what you guys think…. I know I don’t have enough light in tent (300 watts LED total for 4x4 tent) will it alter the quality of the buds or just quantity not having proper wattage?

Looks great!

No reason not to get quality buds. Try optimizing your canopy to your LEDs footprint as best you can.

Day 20 into flower, no smell yet but buds are starting to size

 

[Jsimp342]

First sign of trouble I have seen so far, any thoughts? Only saw on one or two leaves. Just watered again we’ll see how they come out of it

 

[jguit]

Is it effecting only leaves closest to your lights? Maybe back the lights off a touch.

I raised them a few inches maybe I can try a bit higher, can’t imagine it’s heat stress plants are only an inch or two closer to light because I still have been LST to keep them even. Worth a try though

Doesnt look like heat stress but if you push your plants too hard with light they can show deficiencies such a calcium.

So your thinking more of a deficiency than over nute problem? I haven’t pushed nutes that’s for sure. Biggest feed this week I’m planning so far

Looks like the usual Ca/Mg deficiency IMO .

I haven’t flushed plants often. Would my tap well water be considered a flush? Ppm around 250 and ec around 400

 

[jguit]

It resembles a slight Ca issue as @steamroller mentioned. This can be brought on by pushing with too much light, or simply needing more calcium.

Do you have a quantum sensor to measure your ppfd?

No just a ph and ppm/ec reader

I'm not a soil grower but i don't think a flush is necessary or helpful.

Ok I was just reading if you don’t flush enough salts can build up and lockout nutes. I think my water is pretty darn good (drilled well) and using fox farm nutes I don’t think I’ll have trouble

 

[jguit]

I know that is true for hydro/soilless but again, i'm not a soil grower. That said, flushing soil doesn't seem like a good idea.

Thanks for advise I’ll keep an eye on them, raised lights and did a good water today

I didn’t realize this strain of diesel is a 10 week flower lol I got 7 weeks to go! Hope I can keep them healthy that long

I grow in FFOF and coast of Maine Stonongton 50/50 mix .
I use tap water that is 7.6[ real ph after water has gassed to equilibrium ,not just ph'd out of tap which is just so wrong in many ways ].
I have never in 2 indoor grows I documented here done 1 little thing to my water to adjust ph .
I add Ca/Mg 2 times a month .Not just a little either IMO.
My understanding which is limited [ I am a noob here] is that it is pretty hard to over dose Ca/Mg ?
With that thought in my head I dose like I need to without concern for overdose .
My tap is 350 +_TDS ph 7.6 kh2-3 ,gh 9.
There are mineral springs in my area and my plants still need more added to water .
