Has anyone ever grown Mendo Purps?

After the previous run I assumed the many mistakes I had made was why my yeild was less than adequate. Now i'm not so sure. My current run I have 2 OG Kush, 1 Lasqueti haze and after much thought decided to do just one Purps. The entire grow for the purps has been problematic while the rest are rock n'.(all on same regimine) What i'm now trying to decifer is wether this purple is a very hungry type that can be pushed or better leaned out. Since my dude started it from seed and gave me clones from it, not sure if she's just a weak plant. I don't really have a marker to go by cause he has less than adequate conditions and all his seemed to have the same prob. My conditions are not perfect either but way better than his. I have trouble keeping the solution temps below 70 if the room temps go above 70. So that is what I keep the ambient at to avoid root rot. I can easily use frozen water bottles but my buckets only hold 2 gal and I would have to put in and remove many times in the 12hrs the light is on because the sol temp plumets in a matter of mins. I realize growth slows when temps stay cooler so that ads another element to the question. If anyone has exp with this finiky bitch, some input would be awesome
