A week and a half flowering problems. +rep to any help!!

The strain is a GWS it is in some high temperatures about 85 or so. I think it is a PH problem but we test the PH every time we water with a digital PH meter. But it looks like a lot of deficiencies. You guys take a look and let me know thanks.

Think about lowering your temps a bit like closer to 80, as for your problem its kind of hard to identify from the pictures as your condition isn't all that bad so I will refer you to this chart that I often use when diagnosing deficiencies.
Deficiency Chart

you didnt say what method of growing your using. where is your ph at? lower your temps. whats your feed schedule? how did it change when you switched to flower? why does your photo say 6/9/06? what nutients are you using as well as additives? really your looking pretty good except for leaf curling and some ugly leaves. old yellow leafs are acceptable throughout growth stages. you might need to leach salt as that will lock out nutes. otherwise more info please.

Ok as far as the date the camera isnt set. Well since I first posted on here I went and got some distilled water and completly flushed the GWS with 5 gallons of it. The Ph read out was at 5.2 with the first 2.5 gallons flushed. I am trying to lower temps with a fan but we are awaiting a portable AC unit on the way so that will be handled. I am using some bloom booster I got from Lowe's I check the Ph before I apply to the pot always. I understand the yellowing of the leaves is normal to a certain degree but the leaves feel like crispy paper at times. I am thinking Ph lockout because I have some copper looking circles on the leaves. This all started when I placed the GWS on to its flowering cycle. But when I Ph test my solution going into the plant it reads at 6.2-6.4. Thanks for all the help guys. Hell maybe it has something to do with the MG soil does the pine bark crap in it make the soil more acidic.

You want around 6.0-6.5 for a soilless mix, or 6.3-6.8 for soil.

calcium magnesium deficiency probably. ive had this a few times, the lower fan leaves would start to roll and collapse and get crispy. the necrotic spots also.i just hit it with some cal-mag and it cleared up. when i used the mgsoil (budget issues back in the day) it was usually pretty heavy on some things and lacking in a lot of others. i would pick up a bottle of some type of bloom enhancer thats low in nitrogen but has more phos and potassium in it. for instance the npk ratio might appear as 0-10-10 .if you dont have access to a hydro store,you might be able to find something like cactus juice /earth juice or a liquid bloom at your local market/nursery. the warmer temps might aggravate this condition but the plant can make it thru. ive flowered at 90 using similar strains with minimal damage but the stretch was a mofo.

Thx for all the help guys I think the flush will help a lot though.
