Green Gelato vs Sour Zkittlez

You can remove it now if your room humidity isnt extremely low

Hello. Don’t worry about that right now. It’s a great thing you care - but if you find yourself obsessing over scanning every leaf and identifying any imperfection you will drive yourself nuts and likely over correct for a non issue. Just relax, know that cannabis is an imperfect plant and sometimes there are weird things with the leaves that have nothing to do with nutes, environment, etc. That said - don’t be afraid of asking questions here when you have one. If you see other forms of leaf damage throughout the grow post them here. Some pest issues arise and affects leaves. Those you’ll want to jump on asap, but I don’t believe that to be the case here. Good luck

Aim for a ph around 6 this way if it drop it will dropbin acceotable range. Ph tends to swing if temps swings but not this much. Also check your ph after your mix your fert. Fertiliser wil drop ph. So if the water is at 5.5 and you add fertilizer it will drop a 0.8 to 1 easily.. i suggest putting ph buffer instead of changing everything. This low ph will eventually kill the plant du to nutrient intake problemes.

As much as I hate to say it, I would suggest removing the worst leaves, like in picture 3, to stop any potential issues with mould or fungus, especially the damaged leaves closest to the irrigation hosing. Hope this helps,.... Organoman.

I think the pH is too high for your plant to absorb calcium causing these spots to occur, I just cured a calcium deficient plant cause I was feeding with too low of a pH using coco. 6.2 and under is perfect of calcium absorption but since your doing hydroponics id say stay between 5.8 - 6.0 ph

It should be more then safe to cut away the lower 3rd. You have a good canopy going and will provide more circulation. Happy growing and good luck 🌲🌲🌲👊

17 will probably stunt your buds and overall growth. In veg this wouldn't be a problem, but in flower I would highly recommend finding a way to get the temp up just a few degrees. Some strains won't be affected as much, but for many strains, it will hurt the final result a lot. Look up strain info on Google to find their temperature tolerance.

Your root zone looks really healthy. The white stuff you see are actually new roots coming in because I am guessing your clay pellets are covered. The exact thing happens to my grows.. when I take the covers I have off there are roots growing exactly like yours are. Good work.. Smell your clay pellets.. It should smell Earthy.. if it smells earthy your in fine shape. Looks like you good amounts of drainage and a really robust and healthy root structure. What happens down below.. Helps up top :).
