Just a nutrient note - I‘ve been gradually increasing the EC - now at 1.8 (905 ppm) with the following (all per gallon, in order):
1.8 ml Calimagic
0.75g Epsom salt (I’ve noted an apparent increased need for Mg, but not Ca)
6g MegaCrop v1
3 ml ProteKt (0-0-3)
1.5 ml 7.5% battery acid
This provides:
164 ppm N
37 P
212 K
132 Ca
58 Mg
74 S
1.84 Fe
68 Si
I’m starting to see shorter internodes, with the “weaving stems” that signal to me that straight veg is soon coming to an end, and the plants are preparing to transition to flowering. Soon, I’m going to start cutting back on the N and the silica, and start introducing more P. The planned mix will be:
2 ml Calimagic
0.75g Epsom salt
4g MegaCrop v1
1g Greenway 4-18-38 (a tomato dry fertilizer)
1 ml ProteKt (0-0-3)
1 ml 7.5% battery acid
This will provide:
122 N
45 P
217 K
100 Ca
49 Mg
80 S
2.8 Fe
23 Si
