I usually can tell by how heavy or light they are if they are light and easy to pic up then they need water if they are heavy then they dont need water. like I said usually 2-3 days until I water again. They are very dark green now so I dont need to give any nutes yet but I think by day 14 I will give them 1/8 strength DM grow A, B, and DM silica. I already mixed the nutes up in 1 gallon jug of distilled water, I dont ph my water so I use distilled water that usually has a nuetral ph. I put 1ml of each thing in and that is what first feeding will be of then next feeding will be day 20 and I will feed 2ml grow A, 2ml grow B, 2ml Silica, then day 26 I will feed 4ml grow A, 2ml grow B, 2ml Silica and induce flower 12/12 on day 27. I will feed again on day 32(day 5 of 12/12) and I will give them 1 more round of veg nutes to increase bud sites before it shows sex probably like 6ml grow A, 2ml grow B, and 2ml Silica. The bottle says to use the same amount of silica through whole grow but I started the first mix light. After the last veg feeding I will flush on day 8-9 of 12/12 and give bloom nutrients, and DM Silica. The reason I am using Silica for flower is because Silica is for keeping a plant strong and disease, pest, and heat resistant, also to make it grow faster and stress free. Also take note that in between each feeding of nutes I will water thouroughly to clean any salt build-up from the nutrients also to just give them plain good clean water. I use more of the DM Grow A for increasing budsites because the Grow A is higher in nitrogen and lower in phosphorous the DM Grow B is lower in nitro gen and higher in phosphorous so the grow B would have probably been used for Bloom nutes but I ordered some Fox Farms Tiger Bloom, and Big Bloom.
