I know this is only my second post and already asking for help. My apologies in advance.
Anyways, I am using rockwool cubes, my temps never go above 79 degrees nor below 65, I am controlling my tempatures and humidity via humidifier in tent and portable A/C outside of tent. I also have a carbon filter with a large fan and my 600 watt MH and a fan cooled hood. The humidity fluctuates between 35-55 RH (it is very dry around here). I feel they are too young for nutes so I havn't fed them yet. I am sure they will let me know when they are ready for some good GH nutes as I do have the whole lineup. The hydroton has been cleaned. I check the ph/ppm's twice a day and keep the PH level at 5.6-5.8 and the ppm's don't exceed 200. I am using city water (recommended use by a well known local grower here) I let it sit 24 hours before feeding. The temperature of the water ranges from 68-70F. I have the light 28 inches from the top of the plants. I clean out the system every 4-7 days, the light schedule is 18/6.
So most of the things I read on these problems would be due to nute burn/ heat stress/ overwatering/ incorrect PH etc.. I am using bluelab pens for both PH and PPM's and they are calibrated a minimum of once a week. The system I am using is a top feeder by GH called waterfarm.
What I can show you is how it started on previous plants, how it ended, and how it's starting again on new plants.
The strains are Pineapple chunk, tangerine dream, aurora-b, dutch passion blueberry, bubblegummer, jack herer, brainstorm, and super skunk.
The first 2 is a new plant showing same symptoms, third is how it started on last grow, 4th is how it ended on last grow.
Thanks for the help it is much appreciated!
