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

no pics so tough to say.. but could be light-related. depending on where your thermometer is, the temperature more directly under light could be higher, in which case heat can be a potential cause too. 3x2 tent? roughly? 300 watts is a lot of light, especially at 17" from canopy. unless your pushing co2, that's probably a good bit more than you need. so a little more distance wouldn't hurt. plants look healthy, otherwise in the diary pictures, so just a matter of observing.

Week 2: One of the plants still doesn't look good + other beginner questions :)Second week and one of the plants has weird spots + leaves curled. Not sure what to do. Do I overwater? Is it some kind of disease or deficiency? No idea. Also, when should I start feeding the plants? And how much water do I need at this point? 😥

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?

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?
