i have 2 plants that are 3 1/2 week old they are nirvana snow white strain sprouted in pro-mix all purpose potting soil. the last time i'd checked soil ph level it showed someplace between 6.0 to 6.5 (ph liquid tester) with cfl x2 23 w x2 26 w cool white i might have over watered on the 1st and a half week so i stopped watering them until the next 5 days or so. i started watering them again with water soluble nute of 2.5ml 30-15-15 in 3.5 liter water. as you see in the pics i cut off some of the tips on the leaves due to yellowing eventually to browning. please help with what the cause might be. is it overwatering? wrong ph level? nute deficency or burn? any input would be appreciated thanks in advance!
Don't cut off pieces of leaf. That makes it even harder for the plant to keep whats left of the leaf alive. Your plants are way to big for their containers and won't stay healthy for much longer in them. Seedlings should be transplanted into larger containers of nutritious soil when the 3-bladed leaves first start growing in. The light green color of all the leaves looks like the pH is too acidic.
