Got a Problem!

So i got 2 plants... one green o matic and the other is a UFO dinafem or something like that. One of the plants has pretty obvious deficiency with very yellow leafs, but new growth looks nice and green. I had to bump up the nutes faster than i thought, but my other plant is nice and green but has woody dry spots on the tips. i was suppose to bump up the nutes between transition to bloom and when its flowering. so my question is about how long is the transition to bloom so i can know when to bump up to flowering nutes?? right now both plants have a lot of hairs on the top and the nodes, and they have some new growth. And should i worry about the previous deficiency.?

I'am using GH flora bloom

ill post pics in a little for better detail

pics would help but you might not need to bump up nutrients as less is usually better. if you are growing an automatic i would assume you have the light on 18/6 and if this is the case the ufo dinafem will not bloom unless it is an auto too. transition from grow to bloom depends on the genetics. good luck and post some pics if you have some

ask your plants. if it ain't broke...don't try to fix it! Healthy new growth is good...what more do you want? Don't fall into the trap of "more is better" as far as "bloom boosters" go....oh yeah and post some pics

What Powder Kutz said! Good advice man.

Here are the pics.. im actually doing hempy's, this is my first attempt. i keep the ph around 6.5 - 6.7 and like i said im using GH flora bloom. i give them straight non ph'd water once a week and temps are around 75-80. Just looking for any help or advice.

Your plants were Nitrogen starved during vegetation, thus the yellowing, You've obviously started feeding them as the new growth looks much better (darker), but remember to increase their feedings gradually so you don't shock or burn them. Also, don't feed them with every watering. If you notice the tips of the leaves are curling and turning brown, you've given them too many nutrients.
During the first couple weeks of flowering, the plants will grow rapidly. Most strains will stretch like crazy and need a lot of Nitrogen during this phase to build foliage and budding sites. After this initial stretch, slowly ween the plants off the Nitrogen and begin feeding with nutrients high in Potassium. I use organic nutrients with NPK values of 2-2-8 for young plants, 8-2-2 for vegetating mature plants and 2-8-2 for flowering. Works like a charm.
If I were you, I would switch these young ladies back into vegetation (18/6) and allow them to recuperate before flowering them. If they're auto-strains, I guess you just hope for the best.
