Setup:
I am currently growing Sensi Seeds Femenized Big Bud in a GL80 (2.5'X2.5'X6') tent with a 400w air cooled HPS light system. I am using LC's soiless mix #2 with the full botanicare line along with calmag and silica added at the appropriate times. They are waterd with distilled water and nuted every 3rd watering, or as needed with half or less doses as listed on botanicare bottles.
Problem:
The plants are now 2 weeks into flower after a 27 day veg period under floros. About a week ago i noticed that the top sets of leaves, closest to the light, were starting to curl upwards, and in from the sides, almost like praying hands. I posted in the Infirmery but got mixed answers as to what was wrong. I was told too much water, under water, too much heat, and salt build up. The over water and underwatering didnt make to much sense to me because i watered them whenever they were competly dry. I was mainly convinced it was the temps, becasue as of last week, the hood was not air cooled and temps were reaching 86-88 degrees. Now that the hood is cool the room does not go over 76, and is around 69 when the light is off.
Problem is, they plants have gotten worse. They are now all showing severe curing, and not just at the tops, but at lower leaves as well.
Now it seems that the salt build up could be the problem, as the temps have been addressed. Someone told me to flush the soil with water to get rid of the salt build up, but i was under the impression you cannot flush the salts from a fully organic medium with just water. Heres some pics to show u what they are looking like. They were waterd on saturday until plenty of run off came out...
If anyone has any ideas of whats happening it would be greatly appreciated.
