First grow

That might be nutrient burn on the tips of your plants. Try balancing the PH to 6.7, and feed plain water with no nutrients for a week. That will fix the nutrient imbalance.

Yep, young trichomes developing. Nothing undesireable about them.

Those are trichomes, trichomes come in many shapes and size's, those would just be less desirable since it's on a leaf. You could always take a magnifying lens and take a look. If you don't have one, mind aswell invest for harvest time

Feed with half the nutrients before flush then creep back up it will tell you what to do

Ahhhh the clawwwww hahaha I remember that film Liar lol the other growers are correct though i feel both of them have not mentioned the other half of this problem which is overwatering :) Take it easy on the watering can my friend only water when the medium is dry :) Its all good advice though :)

Agreed. excess nitrogen. Since you used only water its most likely you have a salt buildup in your soil from either to much food or not watering enough between feedings. So when you watered it released the nutrients. Dont try to wash them out as it will most likely mess up your soil. Stick to water for the next little bit. And like couplethatgrows420 said if you have a PPM meter check the runoff to see how much it increases to get an idea of how long to keep watering before your next feed. Happy Growing
