Burn Holes?? Or something else?? Help!

I have 18 plants in my grow room at the mo. A few of which have browny yellow patches, crispy edges are they looking burnt? Or are they lacking in something? Or am I just paranoid?? I would appreciate any help..

They stop growing? Did you check the PH?

Nah they still growing like crazy. Nah not the ph of the soil, but the water is always 6.5 - 7 ph.

are they clones?
are you vegging or flowering?
what lights?
what you feeding and watering?
what light sced?
do you have a fan?

they are clones arnt they?.
have they rooted yet?.
if you are vegging you could remove the lower leaves.

Nah they were grown from seeds,
Im doing a veg at the moment. Its been like a week veg (3 weeks all up but they were seedlings).
Light schedule 18/6.
I have only fed them 1/2 strength canna rhizotonic and phd water.
Yes I have an extractor fan with carbon filter, intake fan and small oscillating fan inside...

Check my grow

just cuz the water is doesn't mean it won't change at sometime when you feed your plants

theres ur problem. nute burn. dont give ur seedling any feed for at least 3 weeks.

just water for a week or so, or until new growth starts, then try feeding

well I call nute lock, just cause you tested the water dose not mean your soil PH isn't totally out of wack.... Look around and find a soil tester there are some cheep ones out there sound like ya got everything else taken care of...I bet if you test your soil its at like 5.5 or 5.8 thats about where the brown dead spots and leaf tip curling start showing themselfs...also could be low soil temps...bet it's the soils PH if it keeps getting worse ACE hardware has soil testers and soil test kits, good looking little plants other that that.....I like my soil to be 6.2-6.5 tops, no higher,no lower but thats just me
