Day 53/10

Things are going pretty well at the moment. The new growth is greening up nicely with no signs of mag def. I will start reducing the amount of epsom salts from now on. At some point I think I will switch over to cal-mag again, they might need a bit more calcium once they really start to flower. I've seen pistils on all four plants by now and they're still stretching a lot. I'm trying to spread the tops out evenly but it's a bit like building a puzzle where the pieces are constantly changing . The plants are completely interleaved now so it will be interesting to figure out which bud belongs to which plant come harvest time.

It's been pretty hot lately but running 12/12 it's still possible to keep the tent at a reasonable temperature. However, it's also been quite humid, up to 60-65%, so I ordered a 9400 BTU "portable" AC that can also be run in dehumidifier mode without cooling. I should be all set for flower now.

You really are putting together a PERFECT scrog....I love seeing a perfectly uniform square of bud sites.

Can't wait to see the skyline once the buds start rising like skyscrapers. All getting the same perfect light.

Thanks Trapper, I really appreciate that! The goal would be to have a carpet of bud from wall to wall :smoke:. I still have a bit of work to do to even out the canopy but it's looking pretty good.

It looks damn good to me budster. And I'm glad you've sorted that mg problem.

 

[Grim Reefer]

Looking lovely now dirty budster. Really nice scrog you got going on.

Thanks revert! I'm really glad too I'm also glad I'm running photos this time so I could let them run a bit longer in veg to recover.

Looking lovely now dirty budster. Really nice scrog you got going on.

Thanks Grim! It's turning out pretty well. It definitely has potential to be my best grow yet.

Day 56/13

I thought the stretch was over but after yesterdays feeding they've been stretching a bit again. It's definitely slowing down though so I think it's time to let them go. I still have some fine-tuning to do on the position of the tops and then I should be all set for full flower. Some of them I trained a bit too far so I pulled them back again.
The leaves are a quite dark shade of green and I think I saw a wee bit of clawing on a leaf or two so I backed off the nutes a bit. Yesterdays feed consisted of 2/5 bloom nutes and a full dose of cal-mag. I watered at pH6.5 in and the run-off was 6.5 for all 4 plants. I was surprised to see the pH so close between all four plants, it varied between 6.47 and 6.52.

Thanks Tony!

Day 59/16

It seems the stretch was not quite over. After the last feeding they've stretched another 6 cm in 3 days. They're now about 18 cm above the screen. When they reach 28cm they will be 40cm away from the light, which is probably as close as I would like to go. I managed to rearrange the tops a bit to spread them more evenly across the screen. I tried to leave a bit more space for the main colas as they tend to get bigger.

I cant believe it, is it possible that LED can make so big problems with Mag ?? I'm still using HPS but i would like to start using LED in the future.
Btw, your grow looks great, cant wait to see final result.

 

[dirty budster]

Thanks man! I think the Mg def is a combination of things. There is something in my setup that makes Mg less available, perhaps too much calcium. The LED has a tendency to exaggerate that. I also saw a bit of Mg def when growing under CFL but not nearly as bad and it would resolve once I started feeding them base nutes. I didn't use cal-mag at that time.
