Hi this is my first grow just need some help. I am growing Ice wreck on the left and Sour Diesel on the right. Germinated 15 days ago, planted in medium 2 days later they grew fine cotyledons and first actual leafs grew green but since the last 5 days or so leaves are turning yellow and dead at the tips seem to be more yellow in the grooves of the leaf.
Enviroment:
top fed ------------ 12.5 L of water 2 air stones in 5 Gallon tub
im using general hydroponic flora series nutrients. I put nutrients in when i saw the first leaves, im using just about a teaspoon of each of the 3 nute bottles: they recommend 33ml per 100L for seedlings so basically 33% of 12.5L = 4.125 ml, teaspoon is 5ml so im using just under a teaspoon , and 2 days ago i flushed out the water and put in about 3/5 of a teaspoon thinking i put in too much the first time but doesent seem to be making a difference.
Ligts are 380W LED had them about 16 inches from plants about 2 days ago moved them to about 2 feet
temp was 28celcius now 21-22c after i moved the lights up 2 days ago i also put in a exhaust fan 2 days ago thinking this may all help.
water was also high PH originally as i had no ph meter, when i flushed 2 days ago i put in ph water and ph'd again after nutes to 5.6
Any help is appreciated thanks.
2 days ago before i moved light up and adjusted water they still look the same:
5 days ago they were green with a bit of yellow
