sage n sour burnt leaves and warlock sick! please help newbie grow!

Heya guys, im new to this site and new to growing, as i was given some sage n sour and warlock seeds to try out. i'm not sure what im doing wrong here, as i have been looking and searching for plants similar to my problem, but i can really differentiate well! sorry for the noob me, please help!!!

1) PICTURE OF PLANT *** VERY IMPORTANT ***
2) Growing indoor or outdoors : INDOOR CLOSET GROW
3) Watering schedule : SPRAY FOLIAGE / WHEN SOIL IS DRY 2 INCH DEEP
4) Growing Medium : PERLITE + VERMICULITE + COMPOST
5) What stage of growth : 20 DAYS FROM SEEDS

1st two picture is from Sage N Sour Feminised, with the 2nd picture showing growth on the bottom.

3rd picture showing warlock feminised.

both planted at same time..




both i have given them 1/4 strength diluted tomorite.

You should really start by getting some quality fertilizer and a soil Ph tester if you don't already have one.

yeah, i just got some new all in one nutrient fertilizer. now lacks ph tester. been meaning to get one, but never sure which ones to get.

any idea whats wrong with it from the looks of it? or more details is needed?

It has a major deficiency, probably all three macronutrients to some degree. Those brown crispy leaf edges are probably from Phosphorus deficiency. Bone Meal or Guano teas will help them and some Maxicrop, Kelp Meal or other K-containing fertilizer should be added as well.

thank you very much!

i was very worried thinking that the burns were either light or nute burn thats why i didnt dare to give it more nutes!

try just water till they r 4 weeks old then light dose.

Correct! The cotyledon leaves (little round first set) are actually food for the plant unit it establishes a working root structure. Very important NOT to feed before you start seeing signs of these leaves drying up or turning yellow. Feeding before that happens causes allot of confusion with feeding.

the signs actually showed up before i fed them... one of them, the problem starts before the cotyledon leaves started to yellow, whilst the other started after the cotyledon yellows out.

so what do i do? feed them or just water them? because the symptons seems to be progressing to the top with the top leaves curling down starting to blacken/brown.

You can differentiate between nutrient burn and other problems by checking the lowest leaves, usually the first single- or three-bladed leaves the plant ever grew. Too much fertilizer being absorbed by the roots will hit those leaves first and burn their tips.

Nutrient burn also doesn't focus on the leaf edges like your problem is. It starts at the leaf tip or the entire leaf. Yellowing then browning usually moves down the leaf, middle, edges and all.

^^^^ yeah tive had that problem whatch it
