This is my first grow and I'm having a lot of trouble. These are from seed, and at around 2 ½ weeks since sprouting, my oldest set of leaves started to yellow at the tips, then it started on to the newer leaves once it had far progressed on the older ones. This can be seen in the first pic taken 1 week ago at 3 weeks old. Since then, those 2 sets of leaves in the first pic are fully yellowed and pretty much done for. Now it seems every time a new set of leaves grows out they start to yellow as well. This can be seen in the pic taken today (the plant is 4 weeks old now).
Here is a full breakdown of my setup and routine:
-Both plants are Feminized Hindu Kush (100% indica)
-Water every 48 hours (they show signs of extreme thirst around 72 hours)
-Water pH is usually around ~6.5 (using spring water, left out overnight to get rid of any possibly chloride)
-temp is maintained at 77F
- relative humidity has been kept around 60
-Using 150W HPS, plant tops have been ~9-10 inches from bulb
-There is a fan breezing them 24/7
-Light cycle is 23/1
-Soil mix is :
-3/6 promix potting+seedling soil (75-80% sphagnum peat moss, and the rest is perlite, limestone, and wetting agent)
-1/6 vermiculite
-1/6 worm castings (1-0-0)
-1/6 manure with organic humus (0.05-0.05-0.05) (it might be of importance to note that this big bag has been out in the yard for probably 5-6 years through many winters, and there are various small holes in it....)
I had only fed it nutes once, at a 1/8 dose of 9-9-6 bulb food just 1 day ago since the most recent pic was taken. It didn't seem to help stop the yellowing, and it seems now it made things worse as there are tiny dark spots appearing on the top leaves (as can sort of be seen in the pic). Would you say my initial problem here with the yellowing is actually nute burn from a strong soil? Maybe that manure is bad? I have no ideas now. What do you guys think and suggest I do to fix this issue? I really do not want to have to start over. Any and ALL insight is greatly appreciated. Please help me save my baby! Thanks!
