RQS Royal Dwarf- 1st time budget grow.

So this is day 24 in soil for both plants and look at the difference ! It’s amazing how tow seeds from the same batch, germinated and grown in the same conditions can be so different. Plant 1 is starting to give off a slight pine-citrus smell which is pleasant. It’s about 12cm tall and around 19cm wide. This week was the start of the low stress training to get some light to the lower leaves. He’s loving this and no problems or stress. Watering has gone up to 500ml per day and the ph reducer arrived so it’s getting some fine 6.3 in its system. Plant 2 is being a bit annoying and never looks happy. 10 cm across and about 9 cm tall. Last week we started with some yellowing of the bottom leaf tips. I gave them some coffee for added nitrogen and things cleared up. This week I’m looking at more yellow tips and some slight browning. One of the days the tent did hit 33c due to an issue with my fan. This could be the reason or could it be nutrient burn ? I went with RQS easy grow which is a pellet mix that’s added to the soil once and then that feeds the plan for the duration of the grow. I suppose if there was a clump and the roots find it ,it could cause issues. Unlikely, but I don’t know what else it could be. Any suggestions welcome. The digital temp and humidity readout is great so I’m please I finally have that. Keeping the temp down to under 29 is a challenge as the lights put out quite a bit of heat. I need to move more air so playing around with different fans. So that’s it. Another week. One big boy and one yellow tipped gimp.
