Hi guys...
I was growing in a closet (20 lt nft and under 250w hps) for a few years using cana 2 part nutes and having quite nice grows. My water is very hard with ph around 7.5 - 7.9 and I am using phosphoric acid to bring it down. So till now it was piece of cake. Tap water with acid for ph around 5.8, nutes from A, nutes from B (following the directions from the bottles and reaching full strength at 2nd week of flowering), shake well and in the tank . I added only water with fixed ph when water level drops and change the mix every 10 days. Never use EC meter. PH was allways around 5.5 - 6.0 no mater how many liters of nutes was in the tank... Happy grows!
I stop the growing for a few years an last year I started it again. Although my nutes was way over their expiration day I made again 2 nice grows...
Then a friend gave me a growing tent with 600w hps and i immediately move my 3rd grow (4 x mohan ram) that was in the 2nd week of growing from the closet to the tent. He also gave me the GH flora 3 part nutes. I move my girls to their new house flush them from the cana grow nutes and put the GH following the GH table for dosage (full strenght), using the same amount of acid to my water (now ph 5.5 with nutes) and started the flowering.
Things can only get better i thought! HA! Silly grower!
The first 3 weeks was perfect! The girls have exactly the same looks as before - only much bigger :) - and that look was... perfect for me! But... since the end of the 2nd week i noticed that my girls was quite bigger than before and drink a lot of nutes... i filled up with water as usual... at the end of 3rd week they drink even more and 2 consequent days i find my tank at its lowest with the ph at that level at a very low 4.7! The next day I saw the first spots on a few fan leaves at lower branches.
Since it was scheduled to change the nutes I made the change with fresh ones but with less acid (ph 5.9) so if the water level drops again to have higher ph than the 4.7. For the next 3 days things were stable. No new spots and the ph around 5.7. But the next day... disappointment!
I immediately remove the nutes put water with ph 5.8 and start reading this forum! today is the 2nd day with plain water.. and I am very confused!
I really cant understand whats the problem! is it nute burn or some deficiency? I have to mention that the inner and lower leaves, those between the plants that dont have direct light on them are all good. no spots no problems at all.
Can someone help me please! I need advice on how to fix this if its possible, and then some more advice on feeding plans (lucas or useless?) and if its possible to use them without an ec meter.
Thanks guys for reading all this!!!
