Back in the Congo

Alright, here we are at week 4 of flower and trichomes are now starting to appear and the smell is starting to develop. The stretch is pretty much over now, which is great because I'm essentially out of vertical growing space. Any taller and I will probably need to start tying some of the taller branches down or maybe some HST would do the job. I think I might grow a nice compact indica next, just for a break from managing these tall buggers. Ambient temps and humidity have been high this week again and a dehumidifer has been ordered. I'm having trouble deciding if the top of the plants are showing signs of heat/light stress or nutrient deficiency. The new leaf tips are still slightly light green and ever so slightly crispy in places which makes me think nutrient burn. However, feed has only been 1ml/l bloom this week and some of the top leaves have started developing light green patches (pictured) which makes me lean towards light stress. Maybe it's a bit of mix of both. No trimming of leaves this week, but I am now considering having a fairly aggressive trim of foliage above the screen to improve airflow, reduce humidity (fewer leaves, less transpiration) and improve light penetration to all the bud sites. There are some areas of the screen which have many colas all bunched up, blocking each other from the light and creating a high humidity micro-climate which I am a bit concerned about, but apparently Congo does have high resistance against mildew etcs so fingers crossed. Overall, things are looking good.
