Autoflower tent

@Eauderay, yeah maybe the lights are a bit too low i put them higher today. Also because one plant is growing extremely tall. Double as tall as the other do si dos. Im asking myself if this is good or bad.. The original hanging system on these light are so long i already cant go higher but i have shorter steel wire to fix this i hope they designed them at least shorter on their new lights. (I bought these second hand) The brown spots that formed on the leaves look like rust and learned this is a mold. This is not the lights because it is also developing on the bottom leaves on random places. It has stopped developing but begin this week i ordered a dehumidifier to tackle the problem.. (too humid) one with a compressor to replace my cheap peltier system one and i expect it tomorrow or next week. It is really needed because i have many plants and it is a humid place where i live. 70-80 % will give me huge mold isseus im affraid. I have ventilation going outside etc but it is so humid outside now i cant bring it down with ventilation alone. I also go for drinking wather instead of rainwater now to be safe for spores etc. Im still learning as this is one of my first grows so i didnt expect the humidity problem.

@Canoodle, 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!😉💖

@Canoodle, 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! 😃💖🙏

@Eauderay, 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.

Wow! you could use those leds at 20cm from canopy without any problems? Great strain and lights you have there! Mine just turns yellow and bleached bad if i do that! 🙂💖
