buy a humidifier! i'll post a pic of mine so u know what were talking about!
I dunno....I pretty much trust Jorge Cervantes on grow tips...thats right out of his newest grow book "Marijuana Horticulture the Indoor/Outdoor Medical Growers Bible." vegging plants require more humidity than flowering one's 50 is ideal for flowering...my buddies and I have dialed in on these #'s and having great success. I do agree though...70% might be pushing it....aim for 60-65%.im pretty sure its 40-60%...youd prolly be safe in somwhere in that range ..like 50% or so..
This is part of your problem....there isnt enough humidity in the air when lights come on...plants begin to transpire (because of heat) faster than they can take up water. This is "burning your plants." Get a humidifier! 30 percent humidity is way too low, especially if the day temps are close to 80f...and your night temps near 55f. This is exactlty what this guy is talking about..and it makes perfect sence. So yeah, raise night temps (be aware that heat lowers humidity)...and get a humidifier....should solve the problem....."The present temperature difference between day and night may cause some difficulties. At day temperature may go up to 30 degrees centigrade, while temperature at night may be only 17 degrees centigrade.
Through this, plants have to evaporate too much moisture in too little time when facing day temperature. This may cause so called burning tops. Leafs will show dry brown edges (or they get all brown) and they curl.
New tops will grow, but it will slow down the growing process enormously. It probably takes you several weeks more before you can harvest.
The maximum difference between day and night temperature must only be about 5 degrees centigrade. So it is advised to heaten up a little at night."
this is from another thread and the guys problem looks very similar to mine. with the droopy and purple spots on leaves, ive also noticed very stunted growth...
