Short but one is healthy. Believe its cal-mag deficiency. Any comments could help. Took of 3 of lower fan leaves on one plant. Will post a close ups of the plant and leaves at question. Watered each about quarter of a gallon every day and half or as needed. One handled the little bit of nutrients i gave last week and the other did not. Not really tall enough to lst so I have just been tucking leaves twice a day to make sure new growth at top and future bud sights is getting good light. Ro water ph to 6.5 to 6.6 is all she will get this week. Diary day 28 and day 25 veg.
