Hello there;
I am a first time grower and have noticed that the stems of my plants are purple, I have done some research and found that it could proberly be nitrogeon deficiencies,i started with 6 cloans, 1 didn't do anything so I removed it,1 is not doing very well its very small and the others are going very well 6 x the size when I put them in. not showing any yellowing of the leaves, I was told the strain is pineapple ime growing in a tent,, veg state,600w light,4" fan with carbon filter,4" fan intake,temp 24/28 cent.40ltr hydroponics tank,ph 6.0 and are being fed constantly on the 16 hour cycle,coco feed, with a reading 10/12 cf, can anyone tell me if ime doing anything wrong and will the stems being purple be nitrogeon deficiencies,will it harm my plants, and how I can correct it,ive been told that the nitrogeon comes from my nutrient feed is this right ? if I increase the feed will it solve my problem,, I would welcome any advice,,,,,thanks for your time,,
