GR0WERstarted grow question a year ago

So, it is my problem. Few leaves on the top of the central plant. Idk, what kind of pathology is it and how to kure it. I guessing overheat, but temperature sensor shows 25°c max, lamp to plant distance is about 30cm. Also, they aren't smelly no more. Please, help

lil tip bun, but the curling up on tips and the serated tips around leaf looks environmental. RH is as important as temps. assuming that'snot too low? you get below 40% or near it and "tacoing" can happen. as far as previous comment on light.. the watts are still high but the plants look fine.. still could be contributing to any spike in heat directly under the light. i still think you should wait and see, unless something stands out in your mind about what youve recently done and maybe a temp measurement at canopy level where you see the tacoing occurring. it may be higher than 25c. Slow progression of a problem is a good thing. it takes a small adjustment. rather be certain of the adjustment before compounding the problem with a potentially new one.

What is she telling me?Anyone know what she’s going through? Four weeks old, using tap water with hydroguard and GH FloraTrio nutrients. PH seems to go up from around 5.6 to 6.1 in a matter of hours. Ppm=635 EC=1.2 right now. Been going very easy on nutes, about half strength still. Could that be it?

Surplus or deficiency?Can't tell if there's a surplus of nutrients or a shortage of potassium? One plant looks like nitrogen burn and the other two look like theyre maybe a little k deficient. Was thinking of chilling out on the feed on the burnt one and just feeding micro to the other two. Thoughts?

Looks like light stress I assume with the canoe and curl. Moved light from 100% to 75% Stil at 35in from canopy. Should that do the trick? Also should I have already had it at 75% and moved it to 100% during flower? Or how do you guys do your light power

Day 20 Flower. Leaves curling Leaves curled over 12 hour light cycle. Ph 6.0. Ppm 950. I have been battling ph drop for a week. Lowered Ppm to 900 from 1100. Seems to have stabilized the ph and now the leaves are doing this. I’m looking to do the day 21 strip of most leaves tomorrow. Should I be concerned?

Yellow and fragile leaves 2 week Couple leaves yellowing and bit curved up. I suggest there can be the options: 1) magnesium deficiency; 2) nitrogen deficiency; 3) Light burn. For case it is magnesium deficiency I sprayed the leaves with magnesium sulfate (solution - 1g per 1 liter), but it won't help.

Magnesium Deficiency ? How can I fix it ?got a little deficiency (maybe burned? but I think not). I'm pretty sure it's magnesium's deficiency, it happens after a flushing. I added 2 times the last 2 weeks a little bit of CalMag (BioBizz, but ive bought it 2 years ago, maybe it doesn't work well idk).

Yellow leaves near the harvest This would be my last week of fertilizer watering. And the plant has the leaves turned to the side and with yellow spots. Sign of lack of zinc? I would start making the flush from Friday, is it recommended to start now? In about 2 weeks I will harvest (I tried to water today)
