White spots on new grown leaves

I can agree that fuck neem oil and flushes for a starting grower, but @DissNoof I would disagree too. I think it's mold, early signs of powdery mildew. But it's a guess from few bad resolution photos ...

sorry but i have to disagree with my growmies here. You're absolutely right it really is spidermites and this you can see from the bite marks on the leafs. Many people have some kinds of remedies, but the truth is neem oil doesnt work and chemical insecticides will not work. One of the things that i find works great is Bacilus Thuriengiensis. this will take time to take full effect but the good news is it will control the outbreak very well. If you dont like this method (BT) then try neem or chemical insecticides, but always check the label to make sure it's safe for "food" before you use it on the plant. Hope this helps ! 🚀

yeah may be very early sign of a calcium deficiency https://loudclouds.co/wp-content/uploads/2016/07/marijuana-deficiency-chart-jorge-cervantes.jpg but nothing alarming to worry about at this point imho.

with the krinkly cracked leaf, I would assume your ph is out of balance.

My first inclination is to say this might be the start of some mold issue - or powdery mildew - especially if you're not seeing any critters flying around. Half a gallon of water every 24 hours spells a LOT of moisture that is not going to do your grow much good. Keep an eye on this to see if it a) gets larger or more pronounced or b) starts to spread. This is an especially good article on preventing and getting rid of powdery mildew... but mind you, I'm not completely convinced this is what is happening here! https://www.thehealingcanna.com/growroom-problems%20powdery%20mildew Cut back on your watering - wait until the pot is TERRIBLY light before giving them another drink or feed... The quickest way to kill a grow is to overwater... Good Luck!
