Canoodle

<span class="link_user">@GreenAutoConsumo</span>, merci

<span class="link_user">@Canoodle</span>, Rust? or molds on leafs? Cannabis loves high humidity so leafs well prepared for molds normally.... I have been messing about with my plants with those leds or HPS and the more I push them they burn the stomata on leafs making those burn pattern that looks like plant measles, tips also are fragile being thinner.... Good luck too to you! :smiley::sparkling_heart::pray:

<span class="link_user">@Canoodle</span>, Yes sometimes it is rust but this is not! The rest of plant is healthy only tips of leafs becoming yellow and photons damage on leafs.... those brown spots on leafs can also be stomatas that died from too much light. Humidity is only a problem when buds are big and started to mature. You Definitely need to address high humidity environment then! Good luck!:wink::sparkling_heart:

<span class="link_user">@Eauderay</span>, yes i think it was some mold or fungi in the roots or something with the roots. Bad ph or something is also possible but i know it is not the lights. I blast the 450w version on my other plants (look my other grow) and they do not show burning or any of these signs. You can put the tsw2000 on 20-30 cm no problem.
