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..
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...
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
