Been a long while since posting here so I figure Il post a few pics from the grow this year. Always open to peoples input and more than happy to answer any questions. This year decided to give ILGM a go to see what they'e all about. Received 15 feminized seeds,14 germinated and came out with 13 healthy seedlings Anyways here are some pics and specs on whats going on so far.

here are a few pictures from this year so far. Apologies from the yellowing unfortunately still fighting off a bit of lockout from a week or so ago.

Here are a few early ones

Here are a few more recent. Later on I’ll add a few more showing what strain is what. So far PHaze is the only really showing some color. Hopefully I can turn these around I really put really put them through hell trying to bump up the last feeding.
Week 2/3 of flower for most

Correct me if i should redirect this question but if anyone has any input i would greatly appreciate it. So i ran dyna gro through the entire veg and didnt have any issues but as soon as i switched to the bloom formula i know for a fact i over fed and gave them a bit of nute lockout. I ended up flushing with ph'd water and they seemed to be doing a little better. Let them dry out and came back with 1/2 teaspoon of dyna gro bloom per gallon as well as nftg liquid calcium. At the same time i started using 1/4 tsp per gallon of liquid cool bloom per gallon. I ended up going out of town for a couple days and when i come home it almost seems like they have gotten even worse. Now im really curious if the liquid koolbloom is too potent and ive overfed them again or under fed ive never really had this issue. All plants that are yellowing like crazy are around week 4 of flower.

I’ve already removed quit a few leaves this morning but here are jus a few of them

As far as bud and trichome formation goes everything seems ok it is just the fan leaves and lower branches that are kinda of stretched but any input is appreciated
